DIGITAL TRANSMISSION RANGE (TR) SENSOR DIAGNOSIS CHART

A. TR_V is the voltage at the PCM pin 64 (TR3A Circuit) to signal return.
B. "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.
C. TR_D: 1= Open Digital TR switch, 0= Closed Digital TR switch.
D. 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 (circuit shorted to ground).
1= 9.0 - 14.0 volts (open circuit).

Voltage for TR3A:
0 = 0.0 volts (circuit shorted to ground).
1= 1.3- 1.8 volts (open circuit).
1.8 - 5.0 volts = Invalid Reading (open in wires or bad resistor in digital TR sensor).
