This Week’s Winners

On this edition of Fix of The Week: a bad switch in a Silverado, a faulty remote start in an Equinox, and an overheating Subaru.

 

2003 Chevy Silverado – Rayzor Auto

This vehicle’s four-wheel drive would not actuate. The actuator on the front axle buzzed when put into four-wheel drive and the light wouldn’t turn out. Additionally, the blower motor only worked on high and the blower motor resistor had already been changed. 

We tested: 

  1. The actuator on the front differential which tested – good 
  2. Power on the black/white wire on the actuator connector—no power  
  3. The four-wheel drive fuse and 10-amp brake fuse 
  4. Power at all ignition 3 spots in the fuse box—all had 9.8V 
  5. Power at ignition 3 on ignition switch which had 9.8V, all other pins had 12.5V 

All this testing led us to suspect a bad switch, so we replaced the ignition switch. All issues related to the ignition 3 wire were fixed.

 

2016 Chevy Equinox – 309 Auto & Tire

The car came in with an inoperable remote keyless and you could still hear the key in ignition chime even when the key was out. We found no codes in any module and checked and confirmed the signal from both key fobs. We discovered the key flap on the ignition key cylinder was sticking open with the key out. The BCM thought the key was still in the ignition and was disabling RKE functions. We lubed the ignition cylinder to get the door to work and key fob lock operation and remote start functioned properly.

 

2012 Subaru Outback – Family Auto Service

After testing this vehicle for about 6 miles, we confirmed the customer’s complaint of overheating. We initially suspected the head gasket, but upon tear down found the timing belt had stretched to the point that it was slipping at the water pump. If you can spin the water pump by hand with the belt on, there’s your problem. We replaced the timing belt, pulleys and tensioner along with the water pump.

This Week’s Winners

Welcome back! It’s a brand new year and we have brand new stories and head-scratchers for another year of Fix of The Week. On the inaugural 2019 edition: a smelly Honda Fit, a buck Hyundai, and a Honda Civic that can’t stop won’t stop.

 

2013 Honda Fit – Import Minded Inc.

The customer came in with a complaint of smelling gas in the vehicle. We didn’t find any issues with the system, but a lot of forums suggested checking for loose spark plugs. We checked all 4 cylinders and found cylinder 2 with a fully carboned up coil and plug. The plug was loosened by hand. Three of four plugs were loose upon inspection. We replaced the spark plugs and gas smell was not present during the test drive.

 

2012 Hyundai Santa Fe – HIS Garage

The vehicle came into the shop bucking sharply—very bad at times. The customer had been out of state when the issue arose and had been driving for an extended amount of time. They sent in a picture of the speedometer at 70mph and tach at 0. The engine then completely cut off.  They took the vehicle to the dealer who confirmed no engine codes though abs codes were present. We had replaced both wheel bearings a couple months ago and the dealer thought the wheel bearing was causing the engine hiccup.
When it came into the shop we checked for codes—no pcm codes but abs codes present. We test drove 30 miles and the car bucked once; it felt like more than just 1 cylinder, like no spark then spark. The spark plug gaps looked good but the spark plugs had 100k on them, so we checked Direct-Hit and found another case where the poster had rear abs codes with bucking.
We replaced the crankshaft sensor based on Direct-Hit and replaced spark plugs as maintenance. Issue fixed!

 

2004 Honda Civic – US 12 Auto Repair

While driving down the road, this car’s engine kept accelerating. In neutral, the engine would rev until rev-limiter maxed. We found the rubber intake duct between airbox and throttle body deteriorated and a piece of rubber stuck between the throttle plate and housing. We removed debris and replaced rubber duct which fixed the issue.

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.
