Yes it should and the person at AutoZone should be able to pull the codes for free as well. With no SES light - there might not be any codes which I would more strongly suggest getting anything read for free. P0171, 0173, and 0174 seem to relate to possible vacuum leaks.well, the reason I need this is for a check engine light. Will this scanner give me codes for a Vacuum leak, fuel, etc? I just need to know cause my car was ideling rough and then shut off on me yesterday. now is running fine and NO check engine light. Idel is still sketchy in the morning. I did some research on [email protected] but didn't get a direct answer.
