Thanks matey - that is useful. So by my reckoning, the figure between 11 and 17 for voltage should at least vary between throttle positions. All is pointing to a faulty sensor at this point then!
OR - a bad connection between the TPS and the ECU on the wiring......
That said - if it was a bad wire, you would expect the default position to be 0v, not 5v
