Position Sensor Monitoring
WARNING: This page is about a different car, the 2005 Jaguar XJR, 2005 Jaguar XJ8, 2004 Jaguar XJR, and 2004 Jaguar XJ8. However, it is still accessible from the selected car via links, so may be relevant.
The TCM can identify errors with the position switch located within the transmission. If an unrecognized position code is read by the TCM a plausibility fault will be logged. (A code is checked between positions).
The position switch outputs a 4-bit code to the TCM, the bits being labelled L1-L4. For the transmission, the following codes are used to identify the selector position.
Only for the automatic side of the J-GATE P,R,N,D.
