Gear Selector Position Sensor - Gear Engaged

Gear Selector Position Sensor - Gear Engaged





The gear selector position sensor is mounted in the gearcase. It contains the reversing light switch, starting interlock switch and switches that 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 gear selector position (see table). The slip contacts may be either closed (ON) or open (OFF).

Circuit Diagram And Contact Relationship Table:

The table describes the relationship between the gear selector position sensor's internal terminals A, B. C and PA, the pins in 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 gear selector position inputs, diagnostic trouble code P0705 will be generated and the transmission will go into limp-home mode.
