- 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.
- EEC-V Control System 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.
