1. TR_V is the voltage at PCM connector 175B, pin 9 (TR3A Circuit)
to Signal Return.
2. "In-Between" reading may be caused by shift cable or DTR sensor
misalignment or a DTR circuit failure of TR1, TR2, TR3A, TR4.
3. TR_D: 1 = Open DTR Switch
0 = Closed DTR Switch
4. Breakout Box readings are taken from PCM signal pins for TR1,
TR2, TR3A, TR4 to Signal Return.
Voltages for TR1, TR2, TR4: 0 = 0.0 Volts (Shorted to Ground)
1 = 9.0 to 14.0 Volts (Open Circuit)
Voltages for TR3A: 0 = 0.0 Volts (Circuit Shorted to Ground)
1 = 1.3 to 5.0 Volts (Open Circuit)
1.8 to 5.0 Volts is an invalid reading and is usually an open in
wires or bad resistor in DTR sensor.
