Transmission Range (TR) Sensor Diagnosis Chart





a Will read "Drive" if TCS is cancelled.

1. TR_V is the voltage at the PCM pin 38 (TR3 circuit) to signal return.
2. "In Between" reading could be caused by a selector lever cable or TR sensor misaligned or a TR sensor circuit failure of TR1, TR2, TR3 or TR4.
3. Readings taken from PCM signal pins for TR1, TR2, TR3 or TR4 to signal return.
- Voltages for TR1, TR2, TR4:
- 0 = 0.0 volt.
- 1 = 9.0-14.0 volts.
- Voltage for TR3_V:
- 0 = 0.0 volt.
- 1 = 1.3-1.8 volts.

Wiggle Test Information For Open/Shorts
- TR4, TR3, TR2 and TR1 are all closed in PARK. PARK is a good position to check for intermittent open circuits while observing TR PIDs on the scan tool.
- TR4, TR3, TR2 and TR1 are all open in (D), so (D) is a good position to check for shorts to ground. To determine the shorted components while observing TR PIDs on the scan tool, unplug the TR and see if the short goes away. If the short is still present, unplug the transmission harness and see if the short goes away. If the short is still present, then the short is in the PCM or vehicle harness. Remove the suspect circuit(s) wire from the PCM vehicle harness. If the short is still present, then the PCM has an internal failure. Otherwise the failure is in the vehicle harness.
