DTC P0820 Gear Lever "X-Y" Position Sensor Circuit


DESCRIPTION

The TCM detects the shift lever position using the shift lever position sensor. The shift lever position sensor has two functions; detection and monitoring.
The shift lever position sensor consists of a Link 1 circuit that detects the shift lever positions, R, N, E and M, and a Link 2 circuit that detects the [+] and [-] positions. The circuits are connected to the shift lever via the respective links. The contact switches (6-contact switch for Link 1, and 2-contact switch for Link 2) of the circuits turn on and off in accordance with the fore-aft movement of the shift lever. The TCM detects the present shift lever position in accordance with the ON/OFF status of these contact switches. The transmission shift main switch detects the side-to-side movement of the shift lever. It turns off when the shift lever is in the R, N, or E position, and turns on in the M, [+], or [-] position.
The shift lever position sensor and the transmission shift main switch convert the shift lever position into electric signals and output them to the TCM. The TCM detects the present shift lever position from these signals and operates the actuators to change the gear position.
