Transmission Position Switch/Sensor: Description and Operation
Selector Lever Position Sensor - Gear Engaged
Selector lever position sensor - gear engaged
The selector lever position sensor is mounted in the transmission casing. It contains the reversing light switch, starting interlock switch and switches
which tell the control module which gear is engaged.
Principally, the selector lever 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 select lever position (see table). The slip
contacts may be either closed (ON) or open (OFF).
Incorrect decoding of the slip contacts will cause limp-home to activate.
The table shows the relationship between the selector lever position sensor's internal terminals A, B. C and PA and the pins of connector H10-1 and
those of the transmission control module.
