QuestionDriving today my check engine light came on - what does this mean - what should I expect and what types of questions should I ask when I take her in.
I have been through the 02 sensors with the service engine light - actually found out what it was and did the work my self.

AnswerYou should expect that someone with an OBD II scan tool can connect to your vehicle and read whatever faults are causing the check engine light to illuminate.
Once you know the codes, you can go to your shop manual and find out what they mean, and what tests are done next.
In most cases the code will point you to further tests. It does not usually just point to a part to be changed, as many people think
