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).

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.
