Default Scorpio TPS

Having trouble with it cutting out at low speed e.g around 20mph on light throttle.

Diagnostics indicated the TPS was faulty so I renewed it. It runs better but still cuts out.

Measure the voltage feed and one side is 3.0v and the other is 5.0v with the negative pin in the centre.
Is this correct? I would have expected 5.0v each side and the pot act as a voltage divider.

TIA

One wire will be a ground, one will be a +5v supplied by the ecu, and the other the return signal wire to the ecu, which will vary as throttle is opened.

Not sure what the output voltage should be, but its usually set at closed throttle.

Right OK. I measured the voltages on the connector while it was unplugged.

There isn't any way of adjusting the TPS unlike on the Cossie so it can only go on one way.
