For the past few weeks the check engine light has been going on and off intermittently. It has ben extremely cold here in NY so I was kind of figuring it had something to do with that, but don't think so any more. By the time I either get to work or home and I shut the truck off then back on it normally goes off. I finally managed to get a meter on it and found out that it was throwing 12, 13, 25 codes, for the air flow sensor, Intake air temp sensor, and Barometric pressure sensor. I did a bit of research and found that all these codes point to the MAF sensor. Has any body every experienced this group of codes, if so what did you end up doing? I have a spare mass flow sensor I could try but wont be able to swap it till the weekend. I also hear a relay in the passenger side foot well going on and off that I never heard of before this. The truck is running ok but burring through a ton of gas. Any help would be greatly appreciated. Thank you!!

Any help?

The Gurus will be with you shortly. I wish I had an answer for you but I am not a Guru. I am a disciple.

Thank you for your patience. <img src="/forums/images/graemlins/kewl.gif" alt="" />
