So now that I got you in here reading....let me explain.

My car has a full ABC delete after a failed attempt at running an emissions compliant tune (saga began a year ago and not the purpose of this note). As a result my DPF clogged up.

The car is now properly tuned for a ABC delete, the DPF differential pressure sensor has been disconnected and removed. Yet the DDE is still reporting a static 95 psi DPF pressure when monitor the cars parameters. It behaved the same previously when the sensor was connected but hoses routed in a U.

This seems odd. When such high pressures are measured such as when my DPF clogged, does the DDE record this as a hard fault of some kind? Using Carly, I have zero stored codes. If so, does this have any impact on the cars operating conditions? Could the DDE still hunt for mommy and try to perform a regen with this parameter set?
