Digital Transmission Range (TR) Sensor Diagnosis Chart
WARNING: This page is about a different car, the 2004 Ford Pickup, 2004 Ford F550 Super Duty, 2004 Ford F450 Super Duty, 2004 Ford Excursion, and 2004 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
- 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).
