TR3_V is the voltage at the PCM pin 27 (TR3A circuit) to signal return. "In Between" reading could be caused by a selector lever cable or digital transmission range (TR) sensor misaligned or a digital TR sensor circuit failure of TR1, TR2, TR3A or TR4. 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. Wiggle Test Information for Open/Shorts TR4, TR3, TR2 and TR1 are all closed in PARK. PARK is a good position to check for intermittent open circuits. TR4, TR3, TR2 and TR1 are all open in OVERDRIVE, so OVERDRIVE is a good position to check for shorts to ground. To determine the shorted components while observing the TR PIDs, unplug the TR and see if the short goes away. If the short is still present, unplug the transmission harness and see if the short goes away. If the short is still present then the short is in the PCM or vehicle harness. Remove the suspect circuit(s) wire terminal from the PCM connector. If the short is still present, then the PCM has an internal failure, otherwise the failure is in the vehicle harness.
