Question about 2005 Pontiac Grand Prix

Open Question

05 gt grand prix Multiple Warning lights

3 times in 2 days, on start up, I would get 3 warnings. ABS failure, Traction controlfailure,and Variable effort Steering failure. Upon restart,it would be fine. The 4th time I could not "reset" it. The steering is noticably not working right, and the traction control and ABS are all non-functional.
If it was a fuse........the problem would not have "reset 3 times previous to failure.

Ruling out fuse.

Im thinking an encoder on one of the front wheels. An encoder there, I would think, would need to communicate with all 3 of those systems to function properly, resulting in all 3 failures being reported at the same time.

I would guess a "no signal" from the encoder, the computer will abort all systems downstream of that sensor.

Am I going down the right path here?

Thanks...Gary

    My ABS and traction control keeps saying it needs serviced as well. I had it looked at and was told the sensor on the wheel was dirty so they cleaned it but it is back at the shop again for same thing after only a month.Waiting to hear what the problem is this time. Ialso have a strong gas smell in mornings when i first start it so atleast now i know its not just my car w/ theses problems.

This light is usually caused by a problem in the ABS system. A problem in the ABS system will dissable the traction control system. you will need to have the computers scanned for trouble codes.

The traction control system is controlled through the Anti-lock brake system. The way it works is if one of your wheels starts spinning the ABS applys the brake to that wheel to transfer power to the oppsite wheel that is getting traction. If your ABS is bad then your Traction control won't work. To check it I would find a parking lot on a wet day. In an open space mash in the gas. if you hear the ABS system kick in and you don't squall the tires then your good. My guess is you won't. What I would be worried about is will my ABS work. When checking the traction control is a good time to check the ABS. Acclerate to around 15 mph, then mash the brake as your live depended on it. If you hear a motor run and feel a vibration or grind in the brake peddal, then it works.

Try seeing if any of the codes are set off. On your climate control section with the ignition on hold the off and warmer button and the display will cycle through the codes. Could be a wheel sensor I had a c1225 LF sensor. Could also be a problem with the Wheel speed sensor harness see TSB# 0005-25-003. When I called my dealer about this TSB they didn't know anything about it. If you shut off the car and disengage the traction control, in the glove box, do the codes go away?

Good luck

Hi, the wheel speed sensor and tone ring are built into the bearing/hub assembly. Make sure the new hub contains an ABS wheel sensor and the cable was properly connected. If it is properly connected, the new hub may be defective.

What does it mean when the "Reduced Engine Power", "Service Stability System" and "Traction Control" warning lights come on?


You may have to have the harness replaced. Be sure the connector innards stay dry.When they get wet the contacts will oxidize and start shorting to each other and also the oxide is an insulator causing connections to open. Good Luck, I had a water problem with a Ford Flex and even though covered under warranty since I was the second owner they would not honor it. It cost me about three grand so price things out before getting it fixed, the car may not be worth the investment.

Why does my 2005 pontiac grand prix say service variable effort steerin, traction control off, and service abs?


jack up the four points of the vehicle one at a time shake the tire up to down and left to right, you have bad hub assemblies which tells you your ABS IS BAD take it from there and see what lights disappear, keep me posted and we will go from there.

PRE-DIAGNOSTIC INSPECTIONBefore diagnosing ABS/TCS, perform a comprehensive visual inspection of system as follows.Check ABS/TCS wiring harness connectors for looseness. Check harness routing; pay particular attention to wheel speed sensor wiring harness routing. Check fuses No. 1D, 5B and 6B in instrument panel fuse block. Check fuses No. 1 and 2 in underhood fuse block. Check brake fluid level in master cylinder reservoir. Check brake fluid level in Pressure Modulator Valve (PMV) assembly reservoir. Ensure parking brake is fully released. Ensure parking brake switch is functioning properly. Always perform ABS/TCS system functional check before using DIAGNOSTIC CODE CHARTSThe EBCM/EBTCM has self-diagnostic capability, which can detect system failures. Fault codes stored by EBCM/EBTCM can be displayed using Tech 1 scan tester. There are no provisions for flash code diagnostics.Begin ABS/TCS diagnosis with PRE-DIAGNOSTIC INSPECTION procedure. If failures are found during pre-diagnostic inspection, perform necessary repairs, and proceed with ABS/TCS FUNCTIONAL CHECK. See Fig. 5 .If no failures are found during pre-diagnostic inspection, go to ABS/TCS FUNCTIONAL CHECK. See Fig. 5 . The ABS/TCS FUNCTIONAL CHECK will either indicate ABS/TCS is functioning properly or direct technician to various diagnostic procedures such as diagnostic charts, symptom diagnosis or BRAKE warning light diagnosis.CHART D - TRACTION OFF WARNING LIGHT ON CONTINUOUSLY & NO DTC SET (BUICK WITH UH8 OR U2A INSTRUMENT CLUSTER)Circuit DescriptionWhen ignition switch is first turned to RUN position, EBTCM goes through a self-test, which lasts 2-4 seconds. During self-test, EBTCM commands TRACTION OFF indicator warning light on. Powertrain Control Module (PCM) can also command EBTCM to set a Code 75 which will illuminate TRACTION OFF indicator.Traction control switch is located either on instrument panel center trim plate or driver's front door trim panel. Switch allows driver to select traction control mode (on/off). When traction control system is turned off, TRACTION OFF warning light comes on.EBTCM monitors transaxle temperature through

Have a 2004 Pontiac Grand Prix, Just got the front breaks fixed and I still have a Servise ABS System & a Service Traction System light come on. What may be the problem?


well pontiac have an abs sensor at each wheel and a traction sensor at each drive wheel aka 2 front wheels any one of those sensors could be faulty throwing the warning lights.

that being said your mechanic should be able to pinpoint what sensors are bad with code reader

also if the problem was corrected with repair you had done it could take up to 100 miles to shut the warning lights off

please if this helps you in any way please leave me good feedback thanks

You still have issues with the speed sensors. The wires that connect to the hubs are known for failure.
