P1280 Code Need Help

[redstroker_2002]

Hey guys on my work truck the engine light has been on a few months. I plugged it in to a scanner and got code p1280. ICP Sensor code. I changed the ICP Sensor and still on. Tried clearing it but will clear and then trip the CEL again. From what I understand I am going into a issue blindfolded? The truck is going on a long trip this week and I dont want it breaking! The pcm screwed up??

My truck was running fine - no CEL or codes. Sat for a few days and went to take off in it and won't start. Throwing 2 codes: P1280 and P0472. Any ideas? Can't figure out what happened to it while it was sitting in the driveway.

also am not able to clear the codes - scanner says they are cleared, but when I immediately rescan they are still there

Well, went out to poke around the wiring harness looking for a wire rubbed and shorting or something related to the ICP. Lo and behold the crazy squirrels had eaten about an inch of wire out of the ICP circuit right at the engine wiring harness connector on the left valve cover. Soldered in a jumper wire and off she goes just like a new one. Thanks for pointing me in the right direction through previous posts.
