TR_V is the voltage at the PCM pin 64 (TR3A Circuit) to signal return.
"In Between" reading could be caused by a shift cable or digital TR sensor misaligned or a digital TR sensor circuit failure of TR1, TR2, TR3A, or TR4.
TR_D: 1 = Open Digital TR switch, 0= Closed Digital TR switch.
Breakout Box Readings: Taken from PCM signal pins for TR1, TR2, TR3A, TR4 to signal return.
- Voltages For TR1, TR2, TR4:
- 0 = 0.0 volts.
- 1 = 9.0 - 14.0 volts.
- Voltage For TR3A:
- 0 = 0.0 volts.
- 1 = 1.3 - 1.8 volts.
- 1.8 - 5.0 volts = Invalid reading (open in wires or bad resistor in digital TR sensor).
