Hva betyr feilkoden?

The input shaft speed sensor for even gears, which measures speed for gears 2, 4 and 6, gives a value that does not match the other speed values. The sensor is also used to check the other two speed sensors.

Mulige årsaker

Damaged sensor

Hva du kan gjøre

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 even gears with the other speed values in live data while the car is driving and see whether it deviates
3If 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
4Clear the fault code and road test to see whether it returns
