Question about 2003 Cadillac CTS
The car is running fine? What could be the problem?
Call them before you go but any of the chain auto parts stores will plug in a code reader and clear up the mystery. This is a free service unless a dealer does it.
Your car may have monitoring sensors for many different things and sometimes that warning light only means you skipped some maintenance mileage point and need to have something replaced and the warning light reset. There are a number of different things that have a lifespan (such as the catalytic converter) that is not supposed to be exceeded in order to keep emissions within the federal limits. Ain't govmint grand?
