Was bedeutet der Fehlercode?

The engine control module (ECM) compares the intake air temperature after the EGR supply with other temperatures in the car, such as the mass airflow meter, charge air, ambient, engine oil and coolant readings. The code is stored when the intake temperature deviates too much from these for a longer period, and the sensor signal is too high.

Mögliche Ursachen

Short circuit to ground in the signal wiring
Intake air temperature sensor is damaged

Was Sie tun können

1Read and note the code, clear it, then drive after a long standstill to see whether it returns
2Check that the connector at the sensor in the inlet manifold is secure and free from corrosion
3Use a multimeter to check that the signal wire has no contact with ground (the body)
4If you have a diagnostic tool: compare the intake air temperature in live data with coolant and ambient temperature after a standstill, and see whether it deviates clearly
5If the wiring and connector are fine: have a workshop check the sensor, which is built into the mass airflow meter

Symptome, die Sie bemerken können1

No noticeable symptoms for the driver

Was der Fehler beeinflussen kann1

The control module calculates a value instead of using the sensor signal
