Question about 2002 GMC Sierra

1 Answer

My engine light will not turn off, but the truck is running fine

I bought the truck new in 2002 and haven't had any problems with it. Before we took it to Florida at the beginning of this year, the light was on and I couldn't find a solution. Just before we took it to Florida, the light went off so I thought the problem resolved itself or whatever. Now the light is back on and has stayed on. I've noticed no change in the speedo, temp, rpm; anything. I hooked it up to a reader and it said something with the injectors? would could this be?

There probably is nothing wrong, other then resetting the computer. If you have an owners manual it will tell you how. This happened to me and a friend fixed it in a couple of minutes

2002 Subaru Forester misses/runs poorly with slow acceleration when hot with a/c on especially after running 50-60mph on interstate. Problem is intermittant. Runs fine with excellent acceleration...


I have the same problem. But my check engine light comes on when this occurs. The car runs fine otherwise. The problem manifests when it's hot out and I've been driving for a while with the A/C on. When I stop somewhere (like the supermarket), shop, and get back in my car. It starts fine but when I put it in gear to go, it's extremely sluggish for a few seconds and the check engine light comes on. Then is runs fine but the check engine light remains on. The next day when I start it, the check engine light is not on. Also, I recently had the head gasket replaced. I took it back into the shop the first time the check engine light came on. The mechanic checked it and said everything checks fine. He re-set the light saying to keep an eye on it and bring it back in if the check engine light comes back on. It ran fine for 1.5 weeks and now this problem has started to occur.

Did you find anything out dwbradway? I wish I had a solution for you but I just have the same kind of problem. Any help would be appreciated!

Just bought our 2002 Jeep Liberty. The oil pressure light came on shortly after we bought it. Took the Liberty in for an oil change right away- pressure is fine, no leaks. The light is still coming on and...


How do you know the pressure is fine? What is the pressure? Either the engine is bad, or the oil pressure sender is lying, you need to know ASAP.

Hello and thank you for using FixYa!

I think you mean the code is engine speed sensor. This is caused by a crank sensor on it's way out. I would have the code double checked by a professional, and have the repairs done to correct this. Cause if it's what I think it is, a crank sensor will leave you stuck.

Thanks Jay!

Audi tt 180 quattro car wont start. EPC and E-M system lights on


I would suggest you check oil levels etc. Generally these cars suffer from the air mass meter / air sensor problems aswell as coil problems too. Did you ever get a solution to the problem?

check airflo sensor or potentometer,throttle pos sensor; if revs are to low when turning the wheel the power steering pump will draw power from engine, causing your other problems
