Drive with caution — fix soon.
This code means the intake air temperature sensor is sending a signal that reads too high, which the computer interprets as extremely hot incoming air. The IAT sensor helps fine-tune the fuel mixture and ignition timing based on air temperature. A high signal usually points to a wiring break, a bad sensor, or a poor connection.
$75 – $250
Varies by vehicle and root cause.
Yes, usually. This code rarely affects daily driving, but it's worth fixing so the engine keeps its fuel and timing settings accurate.
Often $75 to $250. A wiring or connector repair is inexpensive, while replacing the IAT sensor adds parts and labor.
It's a low-to-moderate concern. It won't strand you, but leaving it unfixed can slightly hurt fuel economy and emissions over time.
It means the sensor's signal voltage is too high, which the computer reads as very hot air. This usually points to a broken wire or open circuit rather than actual heat.
