I have a 2007 gtp with the 3.6. In live data on my scanner the IAT sensor is stuck at -40°. Trouble codes are p0113 and p0174. I've checked all wires and harnesses. No shorts or open circuits. Bench tested the IAT and it works normally. Getting a good 4.98 reference voltage on the IAT wires. So, did my ECU just crap out on me?
