Gear selector position sensor - gear engaged
| Gear selector position sensor - gear 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).

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.This project is supported by memberships and donations. If you use this site, please consider Joining SCNA and/or making a donation.
