Gear Selector Position Sensor - Gear Engaged

Gear selector position sensor - gear engaged
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 powered via +15. A number of slip contacts power the sensor outputs. The combination of terminals A, B, C and PA indicate the current selector lever position (see table). The slip contacts can be either closed (ON) or open (OFF).





The following table describes the relationship between the gear selector position sensor internal terminals A, B, C and PA, the pit in the connector H10-1 and the control module.





To ensure that the control module receives accurate information, it is important for the sensor to be correctly adjusted. Special tool 87 92 467 should be used for adjusting the sensor.

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.
