I went out this morning and pulled some codes from my truck and what I got were: P1139, P381, and a P470. I lost my book for my superchip to tell me what thery mean so if someone could help me out it would much appriciated. Thank you! Also the truck seemed to run fine before nut I went and uploaded the tow safe on it, will still run ok??? Thanks.
i am not sure on the 1139 or the 381
but the 470 the sensor is mounted on the front of the engine with a tube that runs over to the pass side exhaust manifold and the tube will get plugged and gum up the sensor, you can remove the tube and sensor and clean them out, i had the same problem on my truck about a month ago and just cleaning it helped me. give it a try to remove the tube just need a 17mm wrench.
