This Week’s Winners

On this edition of Fix of The Week: a sluggish Chevy pickup, low fuel pressure in a Honda and a hidden knock sensor on a Toyota.

 

2003 Chevy Kodiak – East Texas Fuel Injection

This truck was brought in for a low power concern. It wouldn’t go over 30-35 MPH max speed uphill or 2000 RPM. It could hit 45 MPH going downhill but as soon as the throttle was applied the transmission would downshift and the truck would slow down. If you applied WOT, the transmission downshifted but the truck would still not go past 35-45 MPH.

We checked both high-pressure fuel and low-pressure fuel systems. The vacuum in the low-pressure fuel did not drop below 3 in HG and the actual high-pressure fuel PSI matched the desired PSI. No codes were set. This truck was brought to us by another shop that had just replaced the engine and turbo with a GM long block and new turbo from the local auto parts store. Fuel injectors were replaced in January of 2018 and balance rates were within spec. All data stream PIDs look normal.

Eventually, we found a PTO switch on the center of the dash that was turned on. We flipped the switch off and the truck ran and drove normally. It appears that switch got bumped accidentally when the engine was replaced.

 

2003 Honda CRV– Juke Auto

The CRV had intermittent/no start when at operating temperature; if it did start, it had a really long crank.
We checked the fuel pressure and it only was at 34 PSI when idling. Normal pressure when idling is 48-55 PSI. The fuel pressure regulator controls the pressure and is integrated in the fuel pump assembly. We replaced the fuel pump and pressure returned to normal 48-55psi. The fuel pump is easy to access in the vehicle if you fold down the rear seats.

 

2016 Toyota RAV4 – Larry’s Auto Service

This customer’s ABS and traction control lights were on in the dash and the scanner gave a “service Stabilitrac” message. We found a code C0045 stored LR WSS, signal erratic. We raised the vehicle on the lift and found the tone ring corroded with a chunk missing from it (rusty snowbird car in Florida). We replaced the wheel bearing hub assembly and cleared the code, test drove the vehicle and confirmed the fix.

This Week’s Winners

On this edition of Fix of The Week: a flooded Infiniti, a touchy cruise control in a Mazda and a corroded wheel bearing hub on a Buick.

 

2010 Infiniti FX35 – Roger Jordan Garage Inc.

This vehicle would at times crank but not start, and alternatively when not cranking over would make a rapid clicking from the IPDM. The car had codes in various modules and had 19 BCM codes which would come back after clearing. We removed fuse 44 in the IPDM which goes to PCM/BCM and the clicking would stop.
We found that the carpet on the passenger side was wet and the sunroof drain tubes were stopped up. Water had soaked the bulkhead connected next to the BCM—we discovered the floorboard had been wet for 3 months. We dried out the water with a heat gun and cleaned the drains. The vehicle then cranked every time, and codes and clicking cleared up.

 

2010 Mazda 3 – Granite Auto Service

The vehicle’s cruise wouldn’t engage, or it would only do so intermittently. We charged the battery and re-checked the cruise operation. The car had low battery voltage when it started and canceled the cruise operation for that ignition cycle. We replaced the battery and cruise ran fine.

 

2011 Buick LaCrosse – Rick’s Auto Service

This customer’s ABS and traction control lights were on in the dash and the scanner gave a “service Stabilitrac” message. We found a code C0045 stored LR WSS, signal erratic. We raised the vehicle on the lift and found the tone ring corroded with a chunk missing from it (rusty snowbird car in Florida). We replaced the wheel bearing hub assembly and cleared the code, test drove the vehicle and confirmed the fix.

This Week’s Winners

On this edition of Fix of The Week: a surging Acura, a coolant spill in a Subaru and a blacked-out Prius.

 

2010 Acura MDX – Accurate Autoworks

This vehicle’s engine came in due to surging at idle. The check engine light also came on whenever the driver came to a stop after driving on the highway.

We verified malfunction and checked fault codes, which showed P2101 and P2176. We then Inspected the electronic throttle body and found the throttle plate stuck partially open. When pressed, the plate wouldn’t close. When we opened it slightly, it would close after release. We observed that the electronic throttle body was binding internally and contacted the dealer regarding sales history and part availability. The dealer said the part was commonly sold and in stock, so we replaced the electronic throttle body, cleared the fault codes and performed an idle learn which tested ok.

 

2008 Subaru Outback – SNR Auto Service

The Outback was experiencing random multiple misfires. After a hot soak, we found the coolant was low in the radiator and the recovery bottle was full. We filled the coolant and ran the vehicle and observed compression leaking into the coolant jacket through the cylinder head gaskets. We then pressure tested the cooling system, and found coolant leaking into #3 cylinder. Replaying the cylinder head gaskets solved the issue.

 

Toyota Prius – Brad’s Foreign & Domestic

After a road-side towing service replaced this vehicle’s 12-volt battery, it wouldn’t start again. The SES light came on in the dash, but all other parts of the dash and display were dark. We attempted communication with scan tool which was a bust, and there was no power to DLC. We then. checked the HV service connection at the HV battery.

The towing service had disconnected it to change the 12-volt battery but that test checked out; the tow service replaced it correctly. We checked fuses at the under-hood fuse block and found half of the fuses in the block did not have power. Inspection of the 120-amp main fuse revealed voltage through half of the block—the other half had no power. The main fuse has several points that supply power to the various circuits; we removed the clear plastic cover on the large 125-amp main fuse and inspected each leg of the circuits (if any of them are open, the system power will not activate the power relays). We replaced it with a 120-amp and the vehicle ran fine.

This Week’s Winners

On this edition of Fix of The Week: a Honda with a loose bearing, a Camry with malfunctioning heat registers and a LeSabre with a wet spliced wire.

 

2013 Honda Accord – Car Doc On The Island

The vehicle came in with an engine noise that sounded like a nut bouncing around in the cylinder head. The sound wasn’t constant but would change with acceleration. Further inspection showed no misfires nor codes. A quick search in ALLDATA and Google turned up zero results. We isolated the noise to correct cylinder bank and removed valve cover. One of the roller rocker assemblies roller was split and missing its bearing. This also ruined the camshaft lobe. We replaced the rocker assembly and camshaft for the affected bank.

 

2000 Toyota Camry – Commission Scolaire des Grandes-Seigneuries

The customer complained that the center register LH side was warm and RH side was cold. This problem happened infrequently but was now constant. We confirmed the symptom and installed a scanner which gave B1421 and B1424 – permanent codes. We diagnosed and replaced the solar sensor which had the same issue. With the scanner, we monitored the parameter for the LH and RH servo motor, both moved correctly per the shop manual: passenger side (LH) from 0-225, and the driver side (RH) from 255-0. Everything looked fine under the dash.

We removed the center console, the steering column, instrument panel and cluster, instrumental panel reinforcement assembly, drained the coolant and recovered R-134. We removed the evaporator and heater core housing, disconnected all screws, removed the evaporator and inspected all opening doors, which were fine. We replaced the RH air mix servo motor and installed all components. Upon testing the vehicle, the fix was the passenger air mix servo, which worked fine.

 

2002 Buick LeSabre – Maclane’s Automotive

All door, locks, and windows of this vehicle were inoperable except for the driver’s front side. We pulled a massive amount of body codes and the wiring diagram which revealed a splice s302. All problems looked like they ran through this splice. We pulled driver’s seat and found water under the carpet. We located the splice 302 which had corroded and replaced the plastic split device with solder and heat shrink.

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.
