P00AA Intake Air Temperature Sensor 1 Circuit Bank 2
Generic electrical fault on intake air temperature sensor 1 (typically pre-intercooler) 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 P00AA?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
