This Week’s Winners

On this edition of Fix of The Week: A Mazda with low fuel pressure, a misfiring GMC Sierra, and finally a Nissan Altima with no power steering.

2015 Mazda 3 – Canadian Tire Corp

Had a Mazda 3 with the code P0192- Fuel Pressure sensor low circuit. There was a Lack of power when the fuel tank was at half or less and the engine would die on the road when cruising. We tested the fuel pressure from the low-pressure pump and the current waveform of the pump while cruising. The Fuel pressure would drop from 70 psi down to 12 psi and the current would drop from 4 amps down to 1 amp. We fixed the issue with a new fuel pump.

2011 GMC Sierra 2500 HD – Kreider Repair

This Sierra’s Engine was misfiring and bucking intermittently during acceleration. It set code P122A-00 –  Injector 3 Control Circuit Shorted. I verified the Cylinder3 injector was shorting out and causing ECM to shut down the injector by watching misfire datastream on my scan tool.

Inspected injector and ECM connectors and they were ok. Removed cylinder 3 and 5 injectors and swapped locations. Short circuit followed injector 3 and showed short circuit on cylinder 5. This indicated that cylinder 3 injector was faulty. I Replaced faulty injector, installed it in cylinder 5 and programmed new injector flow rates as well as the cylinder 3 injector that was originally in the cylinder 5 location.

2015 Nissan Altima 2500 HD – Tracie Roesbery – Roesbery Car Care

An Altima came into the show with no power steering, a “PS” light on in IPC, and no scan tool communication with the EPS module. There we also U1000 codes in IPC and BCM and code U1001 in PCM.

I Monitored supply voltage at the EPS module 2-way connector and found excessive voltage drop on EPS ground “E61”, in the engine compartment on the right fender, rear of EPS module. I found and cleaned corrosion from the ground bolt at “E61”. Cleared codes. PS operation and communication were restored, and “PS” light was off.

This Week’s Winners

On this edition of Fix of The Week: We’ve got a Forester that refuses to idle and a GMC Sierra with fans that won’t turn off.

 

2010 Subaru Forester –  Danny Sosebee – Lindan Auto Mechanical & Body

This Forester rolled into the shop that would not idle but it ran fine otherwise. First I tried cleaning and resetting the Throttle Body but then found that the alternator was defective and making a whirring noise.  When I unplugged the alternator the issue went away, replaced that alternator and all was fixed.

2010 GMC Sierra 1500- Walt Thrower – HIS Garage

We had a Sierra with where right side engine cooling fan ran on high all the time. Even after the truck cut off and key removed from the switch, the fans would still run. I pulled high fan relay in under the hood fuse block and found it was burnt the on bottom side where a pin comes out. I installed a new fan relay and the issue was fixed.

This Week’s Winners

On this edition of Fix of The Week: We have a Chevy and a Kia both feeling a little underpowered. And we have weird noises coming from the engine of a Toyota Rav4.

 

2005 Chevrolet Colorado – Edward Koegler – Carteret County Public Works

A customer came in with a Chevy Colorado that had reduced power displayed on dash and was running very poorly.

The truck had codes P2101 and P1682 but P2101 was the only code that showed on the mini code reader. Only found the other when I used the Autel scanner. I Found fuse 20 was missing in the under the hood fuse block. Turns out, the customer was trying to diagnose no brake lights and left fuse 20 out of the ETC fuse under the hood. When I replace that everything worked properly again.

 

2012 Kia Soul – Dave’s Ultimate Automotive

Had a 2012 Soul that had loss of power, would occasionally stall and restart. It was able to move but only at slow speed. The Check Engine light would come on with code P0088, high fuel pressure.

I found that the bracket above shifter cable mount, the one that holds the wire harness, had cut its way into that harness and exposed several wires. I repaired the wires and the vehicle ran great, no codes returned, and the monitors all reset.

 

2009 Toyota RAV4 – Chuck’s Auto Repair

This Rav4 that came in had weird engine noise at startup for about a year. The noise had recently seemed to worsen after an oil change. The oil was full, the Check Engine light was not on, and there were no codes. A manual oil pressure test at VVT oil pressure switch test was good 60 psi hot.

When I replaced the oil filter housing and filter, I found that the center of the housing was missing. This caused the filter to collapse which stopped oil volume to the upper end of the engine. After I made the repairs there was no more noise. The center of the filter housing should always have a small diameter shaft that fits in the center of the filter.

This Week’s Winners

On this edition of Fix of The Week: We’re talking about sensor and wiring issues. By the way, if you are not already a customer, Direct-Hit offers three different sets of wiring diagrams for most vehicles including full-color. Learn more by clicking here.

 

2004 Honda Accord – Ed Dorflinger – Auto Shop Of Middlesex

A customer was complaining about low power and limited throttle with their Accord. I found P2138 stored in the computer and performed power and ground check at throttle position sensor, graphed sensor A and sensor B. I discovered that on a slow acceleration the sensor would drop out momentarily, causing the code to set.

One of the issues that causes this code to set is when any voltage at idle or full throttle drops below or above spec for more than .3 seconds. In this case, the sensor A spec at idle was .2  and while the car was accelerating the sensor dropped to zero. I checked the power grounds at throttle sensor to see if there were poor connections at ECM. I also checked the throttle position sensor graft for both A and B sensors for irregular readings and found sensor A was dropping out at the very beginning on a very slow acceleration. I replaced the throttle position sensor, cleaned throttle body, reset ECM/PCM, and performed an idle relearn. Problem solved

 

2015 GMC Canyon – Express Automotive

Had a 2015 Canyon come with codes P0090, P00c8, and a reduced engine power message. Scan tool showed maximum fuel pressure at idle. Found rodent damage to wiring at the high-pressure fuel pump located at the rear of left cylinder head.

Repaired wiring at the connector for the regulator. To get there I needed to move the front driveshaft and remove the oxygen sensor to gain access to the harness, then I was able to repair the wiring through the LF wheel well.

 

2004 GMC Envoy – Javier Rodriguez – R & R Cartech

Driver’s Window switch on this 2004 Envoy was Inoperational and windows and door lock did not work either. I checked the power to the window switch and the was no power at the orange wire at terminal B5 on the 24 terminal’s Gray connector.

The 10amp fuse in rear fuse box was good, however, so I removed the driver’s side floor cover to follow the orange wire and found it was cut in half. I repaired cut orange wire and the window worked again.

This Week’s Winners

On this edition of Fix of The Week: A Subaru that has quit drinking, an oddly hesitant Camry, and a Chevy that refuses to let the music die.

 

2013 Subaru Legacy – Ozzie Bucchi – O & J Car Repair Center

This Subaru wouldn’t take gas. If you attempted to fuel it up, the gas pump would shut off after a few seconds. The first thing I checked was the rubber filler hose that connects the filler neck to the fuel tank. Not visible from the outside, the layers of the hose were separated on the inside which clogged up the hose. I had to remove the whole thing to actually find this. I removed the hose and replaced the filler hose with new OE model – they had revised the design for this hose.

One thing to note, the removal procedure advised removing the fuel tank. Instead, I removed the driver’s rear wheel and inner fender liner and filler neck. This let me get the hose without needing to drop the fuel tank.

 

2007 Toyota Camry – Jones Tire Country

This Camry rolled into the stop and a problem of hesitation during acceleration but only if you were accelerating rapidly. I checked that m.a.f. readings to see if ti was all ok, and monitored the fuel pressures with a manual gauge. I also monitored o2 sensor data and everything was normal per Toyota specifications.

In the end, we found a bug, yes a real bug in one of the fuel lines causing just enough of a clog to have normal fuel pressures at idle and mild acceleration. Turns out the engine was replaced with a salvage engine that had wasps infesting the used parts. We cleaned the lines everything was ok after that.

 

2007 Chevrolet Silverado – In Motion Tire and Performance LLC

Battery light and radio stays on when the engine is shut off. Removing key and opening drivers door did nothing but cycling the windshield wipers to high speed would shut off both the radio and the battery light.

When I disconnect the wiper motor plug the battery light and radio shut off. When I re-connected wiper motor and issue returned. Then I tried Tapping on wiper motor and the battery light and radio shut off. Suspecting an internal short, I Replaced wiper motor back feeding battery voltage into ignition accessory circuit. I also replaced wiper motor and the issue was resolved.

This Week’s Winners

On this edition of Fix of The Week we have Chevy Tahoe with an airbag problem, a 2014 Camry with AC that seemingly has a mind of its own, and finally a Subaru Impreza that’s performance while cruising is anything but.

 

2013 Chevrolet Tahoe – Bruce Power Company.

A Chevy was recently brought in with an airbag code of B0079 – symptom 6. The warning indicated the left front seat position sensor was short to ground or open. I Also noticed that the seat belt sensor thought it was buckled when it wasn’t. Seat position sensor is a magnetic reference switch that reads the metal track for rear (contact) and forward (no contact) positions. It uses common wiring with the seat buckle switch –

I used a jumper wire at the switch plug to verify wiring or defective switch and unplugged the seat harness at the floor to test the wiring for continuity, I found none. Then I removed the seat and flipped over the seat, the buckle and position sensor share a common wire (pink) and the wiring was broken at the 2 to 1 connection. When I repaired wiring the issue was fixed.

 

2014 Toyota Camry – Dinosaur Tire & Road Service

A customer was concerned about their AC on their Camry. The motor speed would vary on the manual ac system, there were noticeable speed changes given away by the pitch of the sound from the vents. I used a scan tool to test the AC speed switch position and found that the desired speed and switch speed never changed. The power and ground were both present at the blower motor and the voltage did not change.

Finally, I used a lab scope to check AC amplifier pulse width request to the blower motor and found that only when on high speed would the pulse width drop out and return, likely causing speed change in the blower motor. I Replaced the AC amplifier and the blower motor operation resumed normal function.

 

2004 Subaru Impreza – In Motion Tire and Performance LLC

When this Subarau came into the shop, the customer said it had poor idling and it felt like it was cutting in and out when cruising. What I found was that the smoke intake tube by the turbo was ripped. I Replaced that ripped tube but it still had the same condition and codes! Come to find that these cars don’t set codes easy checked data found it running rich. I replaced the A/F sensor and everything came back fine.

This Week’s Winners

This week we’ve got three winners. First up is a 2007 Chevy with a loss of power, next is a 2001 Civic with no low beams, and finally, we close this week out with 2015 Nissan Leaf with some interesting break problems.

 

2007 Chevrolet C5500 Kodiak – Craig Marcom.

This Chevy had a loss of power, dead miss on cylinder #3. This car also previously had symptoms of air in its fuel system. The customer told me he had partially disassembled the fuel system several times looking for a hard start/air in fuel problem. Symptoms had improved but still ran rough. Since the car had no smoke from tailpipe at an idle I suspected an electrical problem. Checked injectors and found that #3 injector was dead.

Next, I Scanned for codes and found P0208, P0203, P2155 for injectors 3 and 8 and their control circuit. Inspected engine wiring harness and found injector 3 and 8 control circuit wires rubbed through and shorted to the thermostat to upper rad. hose tube. I repaired the wiring and that solved the issue.

 

2001 Honda Civic – Mike Bott, Torchio’s Auto Repair

Recently, a customer came into the shop with a Civic that had no low beams. When I checked the power of the white/red wire to headlight switch when low beams were activated, I found there was no power going through.

Checked power from multiplex control unit connector C, terminal 1 and found power when headlight switch was turned on. That meant we had a problem with the wire between the multiplex unit and headlight switch. I Traced problem back to poor connection a few inches down from headlight switch. Honda must have performed a repair as per service bulletin a long time ago and the splice did not hold up. Installed new wire from the multiplex unit to the headlight switch. Everything was good to go after that.

 

2015 Nissan Leaf – Bruno Leroux, Arleco Garage

This Nissan Leaf came in with ABS and red Brake indicators on and a brake pedal that goes to the floor. When I scanned it, I retrieved the codes u110d, u1510, and u1000. CAN error codes between Intelligent Brake Unit and ABS unit. Following Nissan diagnostic chart, I saw no visible damage on the connectors and the continuity perfect between the 2 units as well as the power/grounds. There was, however, intermittently lost communication when touching ABS connector by hand. When I replaced the ABS unit connector and erased codes everything worked perfectly.

Fix of the Week

This week we’ve got a 2014 Chevrolet Impala that decides to take a nap at every stop sign. A 2003 Honda Element with no AC. And a 2003 Ford Escape that refuses to go backward.

For a chance to have something you’ve worked on appear as a Fix of the Week, and win a cool little prize for your shop, all you have to do is post your unique fixes in Direct-Hit. Just look up the vehicle you’re working on, click on Post Fix at the top right, then tell us the problem and what you did to fix it.

2014 Chevrolet Impala – Shell’s Service

Recently, a customer brought in their car in and said it would die at stop signs but then start right back up. They said this had happened at least twice in the last two weeks. However, their Impala had no codes and we couldn’t replicate the problem.

Since we found no codes I suspected that it either had a vacuum leak or the MAF sensor was acting up. When I opened the hood to check the MAF connector I found that the air box tube had a crack in it along one of the ribbed portions. What was happening was when the car took off from the stop sign the motor raised just enough to open the crack, which caused it to die. I actually saw this happen with a lot of this with the Honda’s back in the day. I Replaced the air tube between the airbox and throttle body and everything was good.

2003 Honda Element – Hawley’s Tire & Maintenance

A customer came in complaining about no air conditioning in their Element. First, I Examined A/C Clutch and there was no clutch engaging/disengaging. I Monitored low and high side pressures and the ambient temperature and low side pressure were almost even. Next, I took a voltage measurement. Battery voltage was present when the A/C button was pressed and there was no voltage when switch is off. I also verified there was good ground on the body of the compressor. Finally nailed this to a faulty magnetic coil. I replaced the compressor, as well as the receiver and dryer. Installed correct amount of oil in system and charged. Verified the repair was complete and A/C was working on a test drive.

2003 Ford Escape – Scofield Automotive

The vehicle had no reverse but forward gear worked just fine. On top of that, the current gear indicator lights on the dash were showing that more than one gear was selected at the same time. I first checked the transmission fluid and the level was good, the fluid itself smelled fine, and looked normal.

I actually replaced the transmission, with a rebuilt unit and the vehicle still had no reverse so I had to keep digging.

When I unplugged transmission range sensor, all gear indicator lights on the dash went out. I compared the TR sensor voltages to the specifications with the sensor plugged in and the voltages were too low. Replaced Transmission Range Sensor and the car now had reverse while also showing only the correct gear on dash indicator.

Fix of the Week

This week we’ve got a 2006 Chevrolet Silverado that likes to randomly die and start back up. A dead 2011 Toyota Tundra. Then finally, a 2009 Ford Escape that won’t let go of the ignition key.

For a chance to have something you’ve worked on appear as a Fix of the Week, and win a cool little prize for your shop, all you have to do is post your unique fixes in Direct-Hit. Just look up the vehicle you’re working on, click on Post Fix at the top right, then tell us the problem and what you did to fix it.

 

2006 Chevrolet Silverado 2500 HD – Rod Swart

This vehicle would die And starts at random times. Then it would No Start With injectors working and no spark. I checked the ground G102 and found that someone had used an aftermarket connector. I replaced that connector with a new one and cleaned the block. The problem went away after that.

2011 Toyota Tundra – John Dewhurst

The Tundra was towed to the shop as a no start. I started by checking the basics and found no fuel pressure. Then I Tested at the pump for a signal from the Fuel Pump Control Module – I got nothing. Next, I Tested power and ground to the Fuel Pump Control Module – both were present. Replaced Fuel Pump Control Module and the vehicle started right up. The link count verification process in the guild is confirmed and helped to not mistime this engine. 48 between painted links at the cams, and 35 between left cam and crank.

2009 Ford Escape – Matt Griffin

The Customer’s ignition key would not come out of their truck. It started and ran fine, there were no codes, and the key felt like it was going all the way back to the off position. But we couldn’t get the key out. I removed both the ignition switch key part and no binding as well as lock cylinder housing. It all looked fine.

I finally cracked this when I accessed the shifter wiring. I Disconnected shifter harness, and in this vehicle, the ground side of the circuit comes from the shifter. When the shifter makes it into the park position the ground goes away and allows the solenoid in the ignition housing to release, enabling the key to be removed. It turned out the sunroof had failed and not closed all the way. The thought behind it was that Ford wanted to make sure the shifter was in Park and the sunroof closed before you could pull the key out.

This week we’ve got three winners. The first is about a rear stop light not working on a 2003 Chevrolet Avalanche 1500, next is 2015 Ford Explorer with compression getting into the coolant system, and finally then we have a 2010 Toyota Tundra with an engine that is running irregularly.

2003 Chevrolet Avalanche 1500 – Springboro Automotive.

The right rear stop light stopped working. I inspected the bulb and replaced it and it only worked for a moment as it went out while backing off the lift. Next, I checked for power to the bulb and found none.I traced the wiring to the junction block at the right rear of the vehicle. The block is located on the inner rear quarter panel and has four connectors going to it. I unplugged one and found that the terminal had pulled out of the junction block.

So, I put power to the blue wire that goes to the stop light bulb from the junction block and then the bulb was lit. I replaced the junction block at the right of the vehicle, sprayed the terminal contact cleaner and anti corrosion spray on connectors. I cleaned and packed connectors with di-electric grease. The stop lights are working fine now.

2015 Ford Explorer – Tech1690, Christian Brothers Automotive.

The Ford Explorer had compression getting into the coolant system. The hydrocarbon block test failed. During the re-installation, our main timing chain only had one link painted at the crank. After consulting several guides, I found that there should be two painted links at the crank. So I ordered a chain from Ford for verification.

The link count verification process in the guild is confirmed and helped to not miss time this engine. 48 between painted links at the cams, and 35 between left cam and crank.

2010 Toyota Tundra – Kevin Michalec, 2nd Opinion Automotive

A customer had complained of a rough running engine and the dash lights were on. There was engine misfiring on cylinder #4, which is the passenger side second from the front. I got p0304 and p0306 codes. I pulled the data up on a scan tool and looked at misfires live. The only cylinder misfiring was 4. So I checked for spark cylinder #4, which was ok. I then listened the injector with a stethoscope, which was clicking. I performed the compression test. It was zero compression. I added oil to cylinder 4 and did the compression test again. I still had zero psi.

The customer was ok to pull valve cover to further inspect. I found broken intake valve spring on one of the 2 intake valves and was holding intake valve open. I removed most cam main caps, slide out rocker arm, hold valve in up closed position, apply air pressure to cylinder (so valve does not drop into cylinder), and installed the new spring. I replaced the intake valve spring, valve cover gasket, and oil hole o rings.
