I've had the check engine light on/off since the day I bought mine a year and a half ago. I took it in the week after I bought it and... *digs up the paperwork*

Concern: Customer states ck eng light on

Cause: scanned car found code po410 sec air pump fault pulled diag tree found air pump solinoid to have internal short

Correction: replaced secondary air pump solinoid

Needless to say again the light has been coming off and of every since. It comes on about 3 trips out of my 18 or so drives a week on average.

To be honest I've never had a single problem with my car since owning it and I kind of grew numb to the light though it does bother me from time to time. My warranty with the dealership I bought it from runs out in 6 months so I might take it in within the next two weeks to get my money's worth. I'll try to post the results of that trip on the same issue if it can be of help.

Last time I took it in the check engine light came on when I drove away from the dealership.
