1. With the scan tool, read TCM DTCs.
  Are there other sensor or sensor power supply DTCs set?
  
  Yes
  - Check the (F894) 5 Volt Supply B circuit for an open or short to ground. If no problem is found, and using the schematics as a guide, check the TCM connector and all related in-line connector terminals for corrosion, damage, or pushed out terminals. Pay particular attention to all power and ground circuits. If no problems are found, replace and program the TCM in accordance with the Service Information.
