Service Engine Light

[trf62]

I have a Chevy s-10 crew cab that I purchased new. I hit the 100,100 mile mark the other day and the service engine light came on. I assume that this is a preset as I just had it serviced about 2,000 miles ago. How do I reset the computer or turn off the check engine light. I would like to reset it assuming nothing is wrong. If it comes on again I will take it in for service. I just do not want to pay to have them check it out, reset it and tell me nothing is wrong.

Thanks

Disconnect the neg. battery terminal for 5 min. (usually do mine for 10 at of good measure). Then reconnect. Thats it.

The service engine light is there to say you have a problem.

go get the codes read at autozone.

Do NOT clear the memory!

Also, the engine light does not come on to say you are in need of regular service like oil etc...

BlazerLT is correct. You can get a key from Auto Zone and read your codes it will let you know if you are having a problem with alot of different sensors and other things. do not clear it until you have read your codes.

Or if he has a 1995+, they have a small handheld device to read the codes.

i would just disconnect the battery and reconnect it and if something is wrong than it'll come back on, also did you hit a big bump? you might have knocked your o2 sensor loose it's happend to me a lot

[mike1224]

it could be your O2, usually last about 100,000mi.

Go get it checked out before clearing any codes. I know this has already been stated but some disagree. Figured a little push in the right direction wouldn't hurt. I don't believe chevy ever used the "service engine soon light" as a regular maint. reminder so get it checked out. BTW: What year is your truck?

What for, so you will never know what the problem is?
