2001 Saturn SC2 Question: Check Engine light stays on
The check engine light stays on when it sees a fault in the emissions system. This usually also means that your engine is not running as efficiently as it could be. You'll want to have the computer scanned for trouble code(s). If you reset the light without repairing the fault, the light will turn back on. Many Autozone's scan the trouble code for free but you'll want to call first so you don't waste your time. - Andy Y
