Digital Transmission Range (TR) Sensor Diagnosis Chart

A. TR_V is the voltage at the PCM pin 64. (TR3A Circuit) to signal return.
B. "In Between" reading could be caused by a shift cable or digital TR sensor misaligned or a digital TR sensor circuit failure of TR 1, TR2, TR3A, or TR4.
C. TR_D: I= Open Digital TR switch, 0- Closed Digital TR switch.
D. Breakout Box Readings: Taken from PCM signal pins for TRI, TR2, TR3A, TR4 to signal return.
- Voltages for TRI, TR2, TR4:
- 0 = 0.0 volts (circuit shorted to ground).
- 1= 9.0 - 14.0 volts (open circuit).
- Voltage for TR3A:
- 0 = 0.0 volts (circuit shorted to ground).
- 1- 1.3 - 1.8 volts (open circuit).
- 1.8 - 5.0 volts - Invalid Reading (open in wires or bad resistor in digital TR sensor).
