Diagnostics show inconsistency on both TPS tracks. I was hoping to manually test the suspect TPS but failed miserably as I don't understand the setup.
First surprise was finding it had four wires where I'm used to seeing a maximum of three. Secondly, I only got static values where I've come to expect varying resistance when moving the throttle.
Can anyone shed any light on how I can test this or provide the pinouts please?
V6 3.0L Throttle Position Sensor

To clarify:
The throttle is electronic. A cable runs from the pedal to an assembly with the TPS, it seems the TPS then reads the position and sends an electronic signal to a motor that operates the butterfly.
Normal testing is not possible due to everything having to be connected and the ignition on.

Cat's out the bag. It's Toby's V6 so might have to ask in the Pug section if a solution can't be had here.
To probe without disconnecting is possible but it involves piercing the insulator. Not a big problem in itself but something I'd rather avoid if possible.
I forgot to add, the four wires provide battery voltage as well as a stabilised 5v to the TPS (which confounds me even more!). The diagnostic is showing both angle and millivolts but is so slow to update that "smooth and progressive" output cannot be tested accurately.
There is provision to probe test direct but again, we don't know which wires to probe.

The TPS on the later V6 as fitted to Toby's is totally different to the earlier V6. In those it is on the side of the throttle body in the traditional place...

Yep, fully drive-by-wire throttle it is. Quite amusing to watch it in action too.
As an aside, I don't suppose you know where (assuming it has one) the MAF is located?
So what about these four wires/pinouts and can/should I be seeing a varying resistance when rotated or does the TPS need to be plugged in, powered up and probed for voltage readings instead?

Jim, the TPS assembly is actually separate from the throttle body and its motorised butterfly.
Mike, Research shows I do not have a MAF, ECU gathers its data with a MAP which is the sensor on the back of the manifold I pointed out
