Hello and welcome to Justanswer!

There are dozens of possible causes for the engine light coming on. The engine light will come on when the engine controller sees a failure in a monitored component or system and sets a fault code. Literally any failure in the powertrain can turn on the engine light.

The first step in diagnosing the problem is to use a scan tool or code reader to see what fault codes have set and then testing can be done from there. Do you know what codes are setting?
