My Mondeo has an unusual fault and google and searching forums is not helping me, so hoping someone maybe able to help.
The car drives fine, but when started says “Engine malfunction”. I have read the codes with Forscan I get:
P2121 – Throttle/pedal position sensor switch D circuit range/performance.
U0428 –Invalid data from Sasm,
I googled this and found threads saying the throttle sensor was in the accelerator pedal, so I replaced pedal. This has not rectified the fault.
I did some live readings of the modules with Forscan (screen shots below). The accelerator when pressed is not registering on the top 2, but is on the bottom.

I am unable to reset the service light either, when i push accelerator and brake is not doing it

Anyone any ideas please what is wrong with the car? I am a bit stuck with this now.. Also why is there 3 readings for an accelerator?
