Was bedeutet der Fehlercode?

The engine control module (ECM) counts the magnetic poles on the magnet wheel using the crankshaft sensor and checks that the frequency of the signal is correct. If the frequency is wrong, the fault code is set. The cause may be play or oxidised connectors, a damaged magnet wheel or a damaged sensor.

Mögliche Ursachen

Loose connection
Contact resistance or oxidation in the connections
Damaged magnet wheel
Damaged crankshaft sensor

Was Sie tun können

1Read the fault code, clear it and test drive the car to see whether it returns
2Check that the fuses are intact; their locations are shown in the owner's manual or on the fuse box cover
3Check the connectors at the crankshaft sensor for play, and that they are firmly seated and clean
4If you have a diagnostic tool: read the speed signal in live data with the engine running and see whether it is uneven or jumps
5Have a workshop with diagnostic equipment check the magnet wheel and the crankshaft sensor and replace the damaged part if needed
