NOTE: The following refers to illustrations Fig 1 and Fig 2.

1. TR_V is the voltage at the PCM pin 64 (TR3A Circuit) to signal return.
2. "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.
3. TR_D: 1= Open digital TR switch, 0= Closed digital TR switch.
4. 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.
