Transmission Range (TR) Sensor
WARNING: This page is about a different car, the 2014 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
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 at the beginning of this procedure for the location of the TR sensor.
