TR_V is the voltage at the PCM pin 19 (TR3A circuit) to signal return.
"In Between" reading could be caused by a selector lever 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.
Readings taken from PCM signal pins for TR1, TR2, TR3A, TR4 to signal return.
- Voltages for TR1, TR2, TR4:
- 0 = 0.0 volt.
- 1 = 9.0-14.0 volts.
- Voltage for TR3A:
- 0 = 0.0 volt.
- 1 = 1.3-1.8 volts.
