P2101-77 Throttle actuator control motor logged fault
Morning all,
seem to have a reoccurring fault being logged on IID.
PCM-Engine Diesel 3.0L
P2101-77 (6C) Throttle actuator control motor - circuit range/performance - Mechanical failure - commanded position is not reachable
( on 04-01-2023 11:58:42 at 68383 mi )
Comes back straight away once fault has been cleared, no obvious impact on driving or vehicle performance.
Ran some live logs with IID, it was a bit of a stab in the dark as to what required logging to build a picture.
Accelerator position circuit D
Accelerator position circuit E
Engine Speed
Throttle Position
Vehicle Speed
A couple of obvious things that the logs show are that there seems difference between Circuit D and E, E is approximately half of D.
Also the Throttle position is coming back as zero or not logging.
Like I said, logs were a bit of a stab in the dark to see if there was anything obvious.
Anyone experienced this before? Any other logs that would be more relevant?
Any assistance appreciated. Many thanks.

Quite a big difference between the 2 and throttle position reading zero when pedal is pressed and engine under load.
