Was bedeutet der Fehlercode?

The code concerns neutral position sensor A and indicates that the character of its signal is wrong: the frequency of the signal is incorrect. The sensor sends its signal as a modulated pulse or frequency signal, and the fault is checked with the engine running. The sensor measures the angle of the gear lever against the gearbox input shaft.

Mögliche Ursachen

Loose contact or oxidation in the connector
Break in the signal wire
Damaged neutral position sensor

Was Sie tun können

1Check that the fuses are intact. The locations are shown in the instruction manual or on the fuse list
2Check that the connector at the sensor is firmly seated and free from looseness and oxidation
3Use a multimeter to check that the signal wire to the sensor has no break
4If you have a diagnostic tool, check in live data that the sensor signal changes as the gear lever is moved, rather than staying still
5If the fault remains after these checks, have a workshop with diagnostic equipment check the sensor signal
