P00A5 Intake Air Temperature Sensor 2 Circuit Bank 2
Generic electrical fault on intake air temperature sensor 2 (typically post-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 P00A5?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
