P0111Intake Air Temperature Circuit Range/Performance Problem

The intake air temperature (IAT) sensor tells the computer how warm the air entering the engine is, which fine-tunes the fuel mixture. This code means the sensor is working but its reading does not match expected values for the conditions. The temperature signal is present but implausible compared to other data.

Ամենատարածված պատճառներն են՝ Faulty or drifting IAT sensor, Poor connection or corroded connector at the sensor, Sensor contaminated by oil or dirt, Wiring resistance problems in the IAT circuit, Sensor located where airflow or heat readings are skewed։

Սովորաբար անվտանգ է կարճ տարածությունների վրա վարել, սակայն շուտով ստուգել տվեք։

Inspect the IAT sensor connector and wiring, clean the sensor, and compare its reading to ambient temperature at startup. Replace the sensor if its values are clearly wrong. This is a low-severity code and the car is safe to drive, but it is worth fixing for accurate fuel control.
