Hello, I'm Chris. Welcome and thanks for asking your question!
This code indicates a electrical issue with the TR sensor. Unplug the PCM and TR sensor and ohm test from both ends the GY/RD wire at the TR to pin 91 at the PCM then do the same on the LB/YE wire at the TR to pin 64 at the PCM. Verify battery voltage at the TR with the key on at the PK/OR wire. If all tests pass then OHM test the LBYE wire to power and ground, if its shows no continuity then replace the PCM.
Hi Chris! I want to say thank you for answering our question. Unfortunately, my husband wasn't able to find the time to check what you had stated, and we took it in to a Ford dealership and they couldn't figure it out either. They cleared the code completely from the computer and the car ran fine for about four days. Now it's started doing the same thing. GRRRRRRR....we're taking it to a different Ford dealership to see if they can come up with something. Thank you for your time! ~jeanie
