2000 GMC Sonoma: The Service engine soon light came..gas cap..tight

Customer Question

I have a 2000 GMC Sonoma. The Service engine soon light came on recently. I know lots of time this can anything from the gas cap not being tight enough to some major problems. The truck still runs fine. How can I reset the computer so the light will go off?

All you need to do is pull the negetive battery cable for at least 30 seconds.You will lose your radio station memory and if you have a theft lock radio make sure you have the code handy before doing this.
