I recently bought a ms6 and the main issue is that the MAF sensor (the IAT part) keeps exploding when turning the car to the on position. I pulled codes and got a P0113 & a P0102. It'll start without the maf plugged in on limp mode fine but as soon as I plug it in it'll die. I realized that the previous owner had the maf wiring backwards as he was attempting to replace the pigtail. I rewired it using alldata and it still blows the iat bulb up. At the White/Blue wire from the harness I get B+ and at the Blue/Black wire I get 5v. This seems correct right? I tested for any breaks in the circuit and from the PCM to the MAF it's all good. The ENG BAR 15A fuse is still good as well. No short to grounds that I can find and no other components are affected/ no codes that are in the same circuit. I'm wondering if the PO's wrong wiring fried the PCM but I want to make sure that everything else is good before I start throwing parts at it. Any insight would be greatly appreciated. I want to get it up and running. It's at 321k miles and my goal is to reach 500k. Thank you!
