Transmission Range (TR) Sensor

The TR  sensor has a set of Hall-effect sensors that have a pattern of ON/OFF states which are dependent on the PARK, REVERSE, NEUTRAL, DRIVE, 3, 2 or 1 position of the manual valve.

The TR  sensor also provides signals for the starting system and the reverse lights.

The PCM uses the TR  sensor signal as an input for its strategy for shifting and TCC  operation. The PCM also uses the TR  sensor signal for transmission fault detection and diagnostics.

Refer to the component illustration in Molded Leadframe  for the location of the TR  sensor.
