Transmission Range (TR) Sensor
The TR sensor detects the position of the manual control lever shaft. The TR sensor is mounted on the transaxle. The TR sensor allows the vehicle to start in PARK and NEUTRAL positions. The TR sensor output signal is linear over the measurement range and the TCM receives the selector lever position.
The signals of the TR sensor are used for the following functions:
- to recognize the selector lever position.
- to actuate the starter inhibitor relay.
- to actuate the reversing lamps.
No substitute signal is available for the TR sensor.
If the connection is cut, the vehicle cannot be started.
The TR sensor requires to be calibrated through the adaptive learning procedures.
