Check your gas cap.....My check Engine light always comes on if it is loose or not on at all.
it means you should probably get that checked.
How do i reset a service engine light on a 2005 gmc c6500 cat engine
gmc serra engine power reduce,can't drive no power
it means you need to connect it to an odb 2 computer and get the code for whats wrong
The service engine soon light comes on when there is a problem with the engine or transmission. They are both monitored and controlled by a computer. You will need to take the car to a shop or AutoZone can read the codes for free. This will at least tell you what area is setting the light.
Make sure the gas cap is on properly. or, there may be an emissions problem. from what i understand, the only time that the "check engine" light comes on is for emissions (oxy. sensors, intake, etc.).
If your engine light has come on for your 1993 GMC Jimmy, you need to take you car in for service. You should make sure that you have enough oil in your car.
Indicative of problem with engine emission system
To reset the service engine soon light on a 2004 GMC Envoy you can remove the ECU fuse. ECU stands for electronic control unit.
