ok so i finally got my truck scanned its been having a check engine light and abs light on. any ways the codes it said were p1280, p0113, p0603. what do these mean and what should i be looking into ordering to fix it. also been getting some hard shifting so idk if these have anything to do with it or not.

 

Here is the first sticky

P1280 ICP Circuit Out of Range Low
P0113 IAT Sensor Circuit High Input
0603 PCM Powertrain Control Module KAM test error PCM or BATT was disconnected, fuse, open ckt.

id start checking some wiring under the hood there brother. and check rear vss

 

vss was just replaced thought that first to. icp is going to get replaced here soon to has oil in it. whats the Iat though it something to replace or what? going to order all the parts soon and just want to make one purchase so i dont get all the parts at different times

 

Intake air temp sensor I'd just check if it is plugged in good and no chaffed wires to it.
