Transmission Range (TR) Sensor

Transaxle Electronic Control System

Transmission Range (TR) Sensor





The Transmission Range (TR) sensor is located on the manual shaft on the transaxle housing.

When the manual control shaft is moved by means of the selector lever cable, an engagement pin in the inner ring of the TR sensor moves through the different positions. The signals are transmitted to the PCM, the reversing lamps and the starter inhibitor relay.

NOTE: Correct operation of the TR sensor is only guaranteed when the manual selector lever cable is adjusted correctly.

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.
