January 30, 2010, 05:10 PM
The engine light came on my dash, took it to auto zone to have them do a quick check and they came up with the diagnostic code P0174, can you tell me what this is and is the repair costly? I just bought this used truck 2 months ago and now this....Thank you for your help!I think it has to do with the oxygen censor????
