Code result
P00AB
Intake Air Temperature Sensor 1 Circuit Range/Performance Bank 2
Moderate severity
What it means
IAT sensor 1 reading on bank 2 implausible. 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?
