Cm870 throttle issue

[Chamberpains]

What kind of truck and year? I don't know the exact code you have but im pretty sure it has to do with the VGT actuator control module. It has a "P" at the end so it is a Past code or Inactive. If it had an "A" it would be active or ongoing.

You said you replaced the turbo air control valve. Is it the red box under the air compressor on the drivers side or did you replace the air actuator on the turbo? The code could be from the failing control module or if you left the key on when you unplugged the control module. More info is needed. But it sounds like your getting things moving in the right direction.

There are a couple really simple and common problems why high idle will kick off. Speed sensor problems, clutch sensor problems cruise control switch problems, sometimes brake switch problems, neutral switch problems, sometimes reverse switch. It usually, but not always, has something to do with the truck thinking your moving or going to put it in gear.

Again more info on truck and everything you got going on is needed.
