Pulled a p154b

I keep getting it, I just keep clearing it with my v2. Could it be a dirty maf? Where is the fuse located? Could a relay be stuck? This isn't gonna hurt the truck is it?

Intake air heater code. It warms the incoming air in the intake tube to help with cold weather starts. Probably faulty IAH but it wouldn't hurt anything.

Ya I googled it today, I understand where it is. I guess best plan of attack is just check fuses and relays.

Good call on the nut!! LOL boy do I feel like a doucher. I looked over all the wiring, everything like twice LOL. I was about to start testing fuses and relays LOL. The nut wasn't super lose but lose enough that it arced out underneath killed the connection. Really hard to notice unless you put a wrench on the nut, cleared the code with the v2 good to GO!!! Thanks for givin my head a shake 01dmax!!!
