Was bedeutet der Fehlercode?

The engine control module watches what the RPM sensor sends. If the signal is missing, the control module treats this as a fault and the code is set. The fault may lie in the wiring, the connectors or the sensor itself.

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

Was Sie tun können

1Read and clear the fault code, and start the engine to see whether it returns
2Look at the connectors at the speed sensor and the wiring for loose contacts, oxidation and chafing
3Use a multimeter to check that the signal and ground leads are not broken, with the connectors disconnected
4Use a multimeter to check 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. Damage to the flywheel or carrier plate can also cause the fault

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
