Position Sensor Monitoring
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2008 Jaguar S-Type, 2007 Jaguar S-Type, 2006 Jaguar S-Type, 2005 Jaguar S-Type, and 2004 Jaguar S-Type. 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
