- "In Between" reading could be caused by a selector lever cable or Transmission Range (TR) sensor misaligned or a TR sensor circuit failure of TR1, TR2, TR3 or TR4.
- TR PIDs: 1= Open TR switch, 0 = Closed TR switch.
- Vehicle Communication Module (VCM) Readings: Taken from PCM signal pins for TR1, TR2, TR3 and TR4 to signal return.
