Hva betyr feilkoden?

The CEM receives a signal from the gearbox that park or neutral is engaged, and a signal about the gear position sensor's position from the TCM over the CAN network. If they do not match, the code is set. The gear selector may then stay jammed in position P.

Mulige årsaker

A break, or a short to supply voltage, in the wire from the gear position sensor

Hva du kan gjøre

1With the ignition off, check that the connectors at the gear position sensor and the CEM are seated and not corroded or chafed
2Use a multimeter to check that the cable from the gear position sensor has no break and no short to battery plus
3With a diagnostic tool, follow the gear position sensor position in live data while you move the gear selector
4After the work, clear the code and check that the gear selector can be moved out of position P

Symptomer du kan merke1

The gear lever is stuck in P
