Was bedeutet der Fehlercode?

After filtering, the ECM checks the readings of sensors 1 and 2 against the atmospheric pressure reading from the control module's built-in sensor. The fault is set when the difference between them is too large.

Mögliche Ursachen

Contact resistance or oxidation in the connectors
Faulty air pressure and air temperature sensor 1
Faulty air pressure and air temperature sensor 2

Was Sie tun können

1Read the code, clear it and road test to see whether it returns
2If you have a diagnostic tool: compare the air pressure sensor values with atmospheric pressure in live data with the ignition on. The values should sit close to atmospheric pressure
3Look at the sensor connectors for oxidation and loose connections
4If the fault remains, have a workshop check sensors 1 and 2 with diagnostic equipment

Symptome, die Sie bemerken können3

The check engine lamp comes on or behaves abnormally
The car feels poor to drive, with reduced performance and lack of power
The car hesitates, surges or runs jerkily

Was der Fehler beeinflussen kann1

Turbo control is interrupted and the control module uses a modelled value for the boost pressure sensor
