Hva betyr feilkoden?

The input shaft speed sensor for odd gears, which is part of the mechatronic unit, gives a signal that is not plausible for the selected gear. The sensor value is used during shifting, to work out vehicle speed and to check the transmission's hydraulic and mechanical function.

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 odd gears with that for even gears in live data while the car is rolling and see whether it deviates
3The sensor is part of the mechatronic unit, so if the sensor is at fault the mechatronic unit must be replaced, which a workshop should do
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
