Was bedeutet der Fehlercode?

The ECM weighs the mass air flow sensor temperature reading against coolant, outside, boost and oil temperature values. Here the air temperature is too low compared with those values, and the code is stored when the difference is too large.

Mögliche Ursachen

Contact resistance in the connector terminal
Mass air flow sensor with the air temperature sensor inside is damaged

Was Sie tun können

1Read and note the code, clear it and road test to see whether it returns
2Start the engine and, with diagnostic equipment, check that the air temperature in live data is reasonable; if it is not, the fault is present
3Check the mass air flow sensor connector for contact resistance and oxidation
4If the fault remains, have a workshop check the mass air flow sensor

Symptome, die Sie bemerken können1

Engine warning lamp (check engine) lit or behaving abnormally

Was der Fehler beeinflussen kann1

The outside air temperature from the sensor in the rear-view mirror is used instead
