P00AE Intake Air Temperature Sensor 1 Circuit Intermittent Bank 2
Intermittent signal from IAT sensor 1 on bank 2. 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 P00AE?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
