My service engine soon light is on. Is it a sensor?

Asked by Feb 04, 2015 at 12:44 PM about the 1999 Mitsubishi Montero Sport 4 Dr Limited 4WD SUV

Question type: Maintenance & Repair

Car is 16 years old and is now starting to hesitate upon acceleration.

1 Answer

We need to differentiate between the CEL, check Engine Light, and 'Service engine soon'. The latter is an oil change reminder.. When a sensor fails the CEL will light. But if it has not had things like spark plugs, air filter, for a long time it might just be that.
