Transmission Range (TR) Sensor Diagnosis Chart





a Will read "Drive" if O/D is cancelled.

1. TR3_V is the voltage at the PCM pin 27 (TR3_V circuit) to signal return.
2. "In Between" reading could be caused by a selector lever cable or Transmission Range (TR) sensor misaligned or a TR sensor circuit failure of TR1, TR2, TR3 or TR4.
- Voltages for TR1, TR2, TR4:
- 0 = 0.0 volt
- 1 = 9.0 - 14.0 volts
- Voltage for TR3:
- 0 = 0.0 volt
- 1 = 1.3 - 1.8 volts

Wiggle Test Information for Open/Shorts
1. TR4, TR3, TR2 and TR1 are all closed in PARK. PARK is a good position to check for intermittent open circuits.
2. 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 the TR PIDs, 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 terminal from the PCM connector. If the short is still present, then the PCM has an internal failure, otherwise the failure is in the vehicle harness.
