Was bedeutet der Fehlercode?

The fault is intermittent, that is sporadic, and it does not need to be present right now. The engine control module compares the speed from the speed sensor with the speed from the camshaft sensor. If the speed sensor value is lower, this is treated as a fault.

Mögliche Ursachen

Open circuit in the signal or ground lead
Signal wire short-circuited to ground or supply voltage
Contact resistance in the connections
Damaged engine speed sensor
Damaged carrier plate

Was Sie tun können

1Read and clear the fault code, and test-drive to see whether it returns
2Look at the connectors at the speed sensor for loose contacts, oxidation and chafing
3Use a multimeter to check that the signal and ground leads are not broken, with the connectors disconnected
4Check that the signal wire has no contact with ground or voltage, with the connectors disconnected
5If the fault remains, have a workshop check the speed sensor and the carrier plate at the flywheel

Symptome, die Sie bemerken können2

Starter spins, yet the engine will not start
Engine stops

Was der Fehler beeinflussen kann1

If the camshaft sensor has been adapted, the control module uses its signal instead
