P00A7

Intake Air Temperature Sensor 2 Circuit Low Bank 2

What it means

IAT sensor 2 bank 2 signal voltage below expected range — short to ground. 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?
