Digital Transmission Range (TR) Sensor Diagnosis Chart
WARNING: This page is about a different car, the 2003 Ford RV Cutaway, 2003 Ford Econoline, 2003 Ford E550 Super Duty, 2003 Ford E450 Super Duty, and 2003 Ford Cutaway. 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.
- 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.
- 1.8 - 5.0 volts = Invalid Reading (open in wires or bad resistor in digital TR sensor).
