Was bedeutet der Fehlercode?

The engine control module (ECM) compares the intake air temperature after the EGR supply with the temperatures of the mass airflow meter, charge air, ambient air, engine oil and coolant. The signal is too high, and the code is stored when the deviation persists for a longer period.

Mögliche Ursachen

Contact resistance or oxidation in the connections
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 and drive after a long standstill to see whether it returns
2Look at the connections at the sensor for oxidation, corrosion or dirt, and check that they are firmly seated
3Inspect the signal wire for chafing near the body, and check with a multimeter that it has no contact with ground
4If you have a diagnostic tool: compare intake and coolant temperatures in live data, cold and warm, and see whether they follow each other
5If the connectors and wiring are fine: have a workshop check the sensor

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
