Was bedeutet der Fehlercode?

The input shaft speed sensor for odd gears gives a value that does not match the other speed values in the transmission. The sensor is also used to check the other two speed sensors, so the fault can affect how the gears are monitored.

Mögliche Ursachen

Damaged sensor

Was Sie tun können

1Read out the fault codes from the transmission control module. If several speed sensors show faults, the cause may instead lie in the control module
2If you have diagnostic equipment, compare the input shaft speed for odd gears with the other speed values in live data while the car is rolling and see whether it deviates
3Check the connector at the sensor for the odd gears: see whether it is secure, clean and free from damage
4If the fault is inside the control module, it must be replaced; a new module is delivered without software and must be programmed by a workshop
