What does service engine light mean in a 1999 plymouth voyager?

The service engine light in a 1999 Plymouth Voyager indicates that the vehicle's onboard diagnostic system has detected a problem with the engine or emissions system. This could be due to various issues, such as a malfunctioning sensor, faulty spark plugs, or an exhaust leak. It's important to have the vehicle scanned for error codes to identify the specific issue and address it promptly to maintain optimal performance and emissions compliance. Ignoring the light could lead to more serious problems over time.
