Look for a loose clamp on the pressure side of the turbo, check the intercooler for for cracks. As for the rest of the codes they could have been stored for some time, I have a high intake pressure and temp code on my DDEC. What engine do you have?

Sadly i check all this and there was nothing loose or compromised. Called Newell and they past me along to cummins and then cummins said they don't do field work on RV's

Welcome to the forum.

Did the coach restart? Or are you stuck on the side of the road? When you say it lost power, did it derate or totally shutdown?

If the coach restarted with no error codes, then the first place I am looking is to clean all the connections to the engine ECU. Unplug the connectors, spray with contact cleaner, let them dry, and reconnect. Don’t forget the connector for the TPS, throttle position sensor. That one will be in harness connected to the accelerator pedal.

Sorry this is only generic advice.

I was able to get it off the road. I looked up the faults and the noted what they were. I think wanted a minute or so then refired the coach and it limped back to where I was going. 


When i stated it lost power. The engine was still running was the pedal didnt do anything at that point and i have to throttle upon pushing the skinny pedal on the right.
