Gear Selector Position Sensor - Gear Engaged

Overview
The gear selector position sensor is mounted on the transmission casing. It contains the reversing light switch, starting interlock switch and switches which tell the control module which gear is engaged.

The gear selector position sensor is a position switch that is supplied with current via the +15 circuit. A number of slip contacts supply the sensor's outputs with current. Combinations of the A, B, C and PA terminals correspond to the current selector lever position (see table). The slip contacts may be either closed (=ON) or open (=OFF).

The following table shows the relationship between the gear selector position sensor's internal terminals (A, B, C and PA) and the pins of connector H10-7 and those of the transmission control module.





Diagnostics
In the event of a fault in the selector lever position inputs, diagnostic trouble code P0705 will be generated and the transmission will go into Limp-Home mode.
