OBD-II diagnostic trouble code
P0113Safe to drive
Intake Air Temperature Circuit High Input
The intake air temperature sensor's signal is reading higher than physically plausible — the computer sees it as an open circuit condition, which usually points to a wiring fault rather than the engine's actual intake air being unusually hot.
Symptoms
- Often no noticeable drivability symptom
- Possible slightly rougher cold-start behavior, since the computer may misjudge intake air temperature during warm-up
- Check engine light on
Likely causes
- Open circuit in the sensor wiring (broken wire) — the most common cause of a "high input" fault on this type of sensor
- Failed intake air temperature sensor itself
- Corroded or disconnected connector at the sensor
How to diagnose it
- Check the sensor connector for a secure, corrosion-free connection first
- Test the sensor's resistance with a multimeter against the spec table for known temperatures
- Check continuity of the wiring between the sensor and the ECU if the sensor itself tests fine
