Hva betyr feilkoden?

The position sensor for shift fork 1 gives too low a signal, which the control module registers as a fault. The cause may be a wire short-circuited to ground, a damaged sensor or a fault in the control module. Gear changes may then become jerky, late or fail to occur.

Mulige årsaker

Wire short-circuited to ground
Damaged position sensor
Damaged transmission control module (TCM)

Hva du kan gjøre

1Clear the fault code and road test the car to see whether it comes back
2Have a workshop check that the sensor wire is not short-circuited to ground
3Have a workshop read the sensor signals and the supply voltage with diagnostic equipment
4If the values are close to or outside the permitted range, have a workshop decide whether the mechatronic unit needs replacing
