1997 Pontiac Grand Am ABS And Check Engine Light

My husband has a 1997 Pontiac Grand Am and the oil, ABS and check engine light came on, there is oil in the car and we just had maintenance work done on it a few months ago, spark plugs, fuel injector, fuel filter changes the whole works. It sounds rough now. what could it be. He put injector fluid in and the ABS and check engine light are now off but the oil light is still on and the car still runs rough wondering what it could be?

Could be a multitude of problems. Bad sensor, wiring, computer, etc. Running rough means it’s misfiring. Could be a bad injector, spark plug or wire, etc. The oil light being on is probably just a bad oil pressure switch.

I was thinking sensor, but the bad oil pressure switch may be it. Would that be something easy to replace for the average Joe or Josephine?

It is a pretty easy replacement. The oil pressure switch is located in the block, a little upward and right of the oil filter area.

2003 Pontiac Grand Am Engine Light

3.4L engine. Check engine light on the dash. ABS BRAKES NOT WORKING, TRAC NOT WORKING.

Ok, first of all you would need to get the car scanned to see what codes are stored. The problem could be causing the ABS and TRAC problems as well, or that could be a whole other issue. Really need the codes to know for sure. If the vehicle is running poorly, that can set all the lights on due to misfires, etc. If your Pontiac is running fine, but the lights are still coming on, then you have a different issue, such as a faulty sensor reading, or possibly a wiring problem. Any of these would need to be checked out, but first as a starting point, get the Grand Am hooked up to a scanner so you can pull the trouble codes out.

1999 Pontic Grand Am Code P0404

Had advance and a auto repair shop check. both cane up w this code. i know it could be a dirty/bad egr valve. light stays on, however, car runs fine and is fine when in idle as well. do not have the money to buy a new egr valve and might have someone who can fix it. question is, the mechanic told me not to worry about it unless i smell fuel at a red light (which i do not) or if i have to go to emissions (which case i will clear code). car does run fine, is this worth even fixing right now?

The code P0404 on your Pontiac is for the EGR position. Something is going wrong internally with the pintle valve and where it should be as related to where the computer is commanding it to be. Usually this is easily fixed by replacing the EGR valve. If you don’t want to replace it right now, that’s up to you. If the pintle inside the EGR valve gets stuck, you will notice the car running very rough or stalling out. Simply clearing the code will NOT get you to pass an emissions test. If the car’s computer has not run and passed all related emission component tests, you will fail when they hook the car up and see that. Best bet is to just fix the car, plain and simple.

2002 Grand Am ABS Traction Lights

The ABS and traction control warning lights came on my 2002 Pontiac Grand Am while I was driving and then turned left. Are these two lights related to each other? A have read that on can cause the other problem. How to check for codes on my car? Also, the check engine light has come on and off at times but not usually when the ABS light is on. Any help would be great, thanks.

ANSWER: Yes, usually the ABS and traction light are one in the same. If there’s a problem with one, they both set the light on. You probably have a faulty wheel speed sensor or harness. You would need a proper scanner to correctly get the codes stored in your ABS system. The check engine light probably has nothing to do with the ABS problem, but if it’s come on, there is probably a code stored there too for the PCM. If you do end up needing a new wheel speed sensor, they are part of the hub bearing for that particular wheel.

Guest: Good advice. Checking the harnesses for the front speed sensors is very important. Have seen several times where a mechanic replaced the hub bearing only to find out the ABS light came back on. Sometimes a break in the wiring can be hard to find. The outer insulation needs to be carefully removed to inspect each of the 2 wires. If there is a problem, it can be seen as the wire stretches or has a green corrosion spot on it. You can either repair it or get a new harness from the Dealer.

Guest: Get the harness from the dealer. Just repairing the wires may only last a little while, then the light will come back on if you do not do a great job of soldering. Most people do not have the expertise to do a good quality repair for the sensor wires, so replacing the harness is best.
