Why? Just reset it.
my 92 Chevrolet corsica has a rectangular signal that appears on my dash. It is a box with wavy lines at the bottom of it. there is an arrow pointing downward. What does this mean. There are no pictures of this symbol in the manual.
That requires an OBDII engine scanner.
on mine i just changed the o2 sensor located in the front by fan
You need to have it checked for codes. If you fix the cause of the codes the light will stay off.
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.
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.
Have vehicle scanned to determine the problem and have codes cleared
The service engine light is the same thing as a check engine light.
