System: Fuel & Air Metering · Standard: SAE J2012 generic code · Severity: Low urgency
No immediate safety risk. Monitor it and fix it at the next service, but do not ignore it indefinitely.
Many engines share this sensor with the mass air flow sensor, so the two are replaced together.
Start by reading every stored and pending code, not just this one. A single fault frequently sets three or four codes at once, and the first one in the freeze-frame data is usually the cause while the rest are consequences.
The intake air temperature sensor circuit is not returning a plausible value. Intake Air Temperature Circuit Malfunction is a generic fuel & air metering code defined by SAE J2012, so it carries the same meaning on every OBD-II vehicle.
Low urgency. No immediate safety risk. Monitor it and fix it at the next service, but do not ignore it indefinitely.
In rough order of how often they turn out to be the problem: Failed intake air temperature sensor; Wiring fault; Sensor contamination.
