Ok, back home now

Taken TPS off, it's an PF09 so it's the correct one for a 4x4.
Wiring is as per above.

Looking at the TPS with the face which goes against the throttle body on the table, and the connector towards the bottom, I read the following off the connectors:
Idle:
Middle and left - Closed circuit.
Middle and right - Open circuit.
Left and right - Open circuit.

Full throttle:
Middle and left - Open circuit, resistance increases as the throttle opens.
Middle and right - Closed circuit, resistance decreases as the throttle opens.
Left and right - Open circuit.

Is that as expected ?

Also, if I disconnect the throttle cable, the plate inside the throttle body is shut against the body, there is no gap, not even a smidgen.
According to stu (above), the screw to adjust this should not be touched. Does this mean I need a new throttle body ?

Any help much appreciated.
