Park/Neutral Position Switch
The park/neutral position switch is located on the selector shaft, which is connected to the selector lever by a pull cable. The switch informs the transmission control module (TCM) of the current selector lever position.
The selector lever position is transmitted to the TCM in encoded form along 4 lines. The encoding ensures that malfunctions in the connecting lead are identified.
