P00AD Intake Air Temperature Sensor 1 Circuit High Bank 2
IAT sensor 1 bank 2 signal voltage above expected range. The intake air temperature sensor feeds the ECM's density calculation — a drifted reading miscalculates fuel mass and pushes mixture lean (cold reading) or rich (hot reading).
Is it safe to drive with P00AD?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
Common causes
- Most likelySignal wire open
- Less likelyConnector pins corroded - high contact resistance
- Less likelySupply wire pinched against B+ source
