There are pages and pages of things that can cause a check engine light. You need to have it checked with a scantool. Then the code can be diagnosed and repaired.
Check engine lights are designed to give a driver warning of a mechanical issue concerning the car. In a 1991 Chevrolet Corsica, if the light comes on while driving after 10 minutes on the highway, it is best to limit driving to prevent further damage. Check the owner manual for reasons the light may be coming on or let a mechanic evaluate the issue.
on mine i just changed the o2 sensor located in the front by fan
I have a 88 corsica with a 90 cavalier engine in it.
On the website fueleconomy.gov, it lists the 1996 Chevrolet Corsica 3.1L V6 engine at 18 MPG city, 27 MPG highway. I owned a 3.1L 96 Corsica and I got 25+ MPG in the city so for the amount of power the V6 has and given the year of the car, very fuel effecient. Dale, Bristol CT
No idea to be honest, but i have a 95 Corsica with a similar problem that will turn the Service engine light on after a while of driving highway speeds, or after reaching highway speeds and slowing down again. After getting the code read i found out it was for the EGR valve sensor. Basically meaning that its positioning fine at normal in town driving but not working as it should at higher speeds. Again i can't assure you this is a positive solution but i would recommend running your car as you would normally get on the highway and then while the light stays on going to AutoZone (They will run service engine soon checks for free) or a mechanic you trust. hope this helps.
You need to have it checked for codes. If you fix the cause of the codes the light will stay off.
take it to autozone they will check for free. wolverine Probably some problem with the smog controls. Probably nothing too major. If the service engine light is flashing, it's probably major.
The Chevrolet Corsica 3.1 liter engine crank sensor can be found on the back of the engine. You will need to remove the rear engine cover in order to access the crank sensor.

Place something to catch the engine coolant beneath your 1990 Chevy Corsica radiator. Remove the radiator drain plug with a 9/16 ratchet. The engine coolant will drain out.
disconnect the battery for a few minutes
