- 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 and TR4 to signal return.
- Voltages for TR1, TR2 and 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).
