I have a Grand AM GT. My Service Engine Soon light came on recently and I cannot figure out why. I know it is not because of the gas cap because this happened before and back then it was the gas cap and now I religiously turn the cap 3 clicks when putting back on. I recently had a Fuel System Cleaning at Sears and I am wondering if that maybe has something to do with it? The light went off yesterday but came back on today. Also is there an easy way to clear that light, one that doesn‘t require a visit to a mechanic?
Hello With cars they are recommended to be serviced every so often. Yours obviously has an on board reminder. If you check the Service history for your car the next empty on is when the next one is due. This can be because of the Mileage or the time since last service. Andy C
It's time for an oil change. Instructions for resetting the light are in the owners manual.
it could be several things causing it to come on ! it don,t take much for the light to come on ! you need to have someone run the codes on the computer, auto zone and advance can do it for you for free ! it depend on what year your grand am is ! on the older cars you could unhook the battery for about 5 minutes to clear the codes but the newer cars the garage has to do it !
