thanks for all the replies and info. I read up on some of your other postings with other codes, but still related to the Throttle-Actuator.
I can see the throttle close a brief second and then open back up 94%. It stays open while the engine idles or even accelerates. Only when the pedal is released do I see a brief blip of 30-60% open. Otherwise it pretty much stays open.. I guess on diesels they will stay open until the EGR valve is overcome by pressure or the run-away effect?

I cleared the code as step 1, but it hasn't come back on yet after around 40+ miles. I guess it's more like a ticking-time-bomb now? It will fail, just don't know when?

it looks fairly easy to access and swap out. Am I wrong here? no need for coding, etc.. I hope.

So the honest thing is to change it asap? to avoid getting stranded?


Thanks all. very useful info. Especially Zeta and ninja..
