Engine light is on what can cause this

1 Answer

68,735

There are over 100 things that can trigger the check engine or service engine soon light. Have the computer scanned and post the trouble code(s) here and we can help further. Most Auto parts stores will do it for free. The trouble codes will have a "P" then four numbers. For example, P0300, or P0420. HTH. -Jim
