I did a DPF delete using EFI Live in December. At the time I programmed the truck, I had a "service park assist" warning on the EVIC. Since the fault was already there, could the delete program cause the fault to be imbedded in the ECM? I don't get any codes, but the problem persist. I know it is a long shot, but I'm running out of things that could be the problem. I replaced the two sensors that were not clicking and the resistance is the same on all of the pins. A-B, B-C, and A-C. I cleaned all of the sensor connectors and put dielectric grease in all of them. I'm getting 8.5 volts to all of the sensors. I disconnected the battery for 3 hours and it didn't change. Everything should be working with new sensors and the correct voltage from the unit. My only other thought is to buy factory sensors, but at $135 each, I might just live with the problem. I don't need it, but I hate having something that doesn't work.

The mechanic I took it to told me it is a wiring problem, so now I'm tearing into the wiring harness looking for a short.
