I bought a 2000 Chevy S-10, 2.2 Liter engine and has 32000 mile about a month ago and have had multiple problems back to back. The truck was bought from the dealer and was listed as GMAC Certified. I'm trying to figure out just what that means because in my opinion it's not what I thought it meant because of the problems I'm having. First problem was that when I got the truck up to 75 mph, the abs light would come on. They checked and found that the PCM was bad and replaced it. The same day they replaced the PCM, the SES light came on after I had left the dealership and on the way home. I've scanned the codes and get the following codes: P0131 , 02 sensor circuit low volts (bank 1 sensor 1), P0134, 02 sensor circuit no activity (bank 1 sensor 1)and P0325(knock sensor 1 circuit malfunction bank 1 or sensor 1. I'm also getting the foul rotten egg smell from the exhaust and up around the engine compartment. I pulled the 02 sensor past the catalyst converter and checked it by plugging it back to the cable and turning on the ignition. It heats up so I think it's good. I felt the casing of the sensor mounted in the manifold and it felt as if it was heating up also. What could be the problem here?

If it's truly GM Certified, then you may still have some warranty left on it. You automatically get a 3 month/3,000 mile GMPP warranty with a GM Certified used vehicle if it's out of the factory warranty when you buy it.

If you give me your VIN, I can look and see if this is the case.

That's me. Does that mean that I can take it to any GM Dealer and have it repaired. We have a few here that will still try to charge you even though it's covered under warranty.

Absolutely. Just tell them it's a GM Certified and if they have any question, do a GMVIS and they'll see the same thing I saw.

I really appreciate your assistance. I'm going to take it to the dealer this evening.

Thanks

Took the S-10 to the dealer and the problem was a bad oxygen, and knock sensor.

Jamesat40 Armstrong, that is good to hear that your problem was fixed. Also good that GM tech was able to find that info for you.
Glad to hear it worked out.

Ok, the dealer has replaced the oxygen sensor, the knock sensor, a cracked manifold and nothing has changed. Although, I like the idea of having everything on the engine replaced, it's starting to get a bit frustrating. I had told the technician that the problem started after another dealership replaced the Powertrain Control Module last week. They changed the PCM because when I got the truck up to 70mph the ABS light would come on. Replacing that did fix the ABS light but induced the problem that I have now, the SES light came on 10 minutes after I left the dealership. What happens is after the codes are cleared from the computer, you can drive for hours with no light, but as soon as you turn the vehicle off and start it back up, the light will come on within minutes after the truck begins to move.

We don't see it often, but it's possible you could have a bad PCM. There's really no way to test it. The only way is to replace it and see if that corrects the problem. If it comes on after a restart, it should be easy to duplicate and see if replacing the PCM fixes it.

The only other thing I see in common on those two things is ground. So, making sure all the grounds are clean and tight would be my first step.
