Hva betyr feilkoden?

The input shaft speed sensor for odd gears, which measures speed for gears 1, 3, 5 and reverse, is damaged. The transmission control module (TCM) therefore gets no usable speed signal from it. The sensor's signal is also used to check the other two speed sensors.

Mulige årsaker

Damaged sensor
Damaged connector or dirty circuit board at the 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
2Check the connector at the sensor for the odd gears: see whether it is secure, clean and free from damage
3Use a multimeter to check that the wire to the sensor has no contact with ground (the car body)
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
5Clear the fault code and road test to see whether it returns
