After cleaning the throttle bodies and fitting a new TPS switch, still no voltage reading to set up the TPS ??
Car is running at 1400rpm at tick over, and engine fully warmed up.
???????????
No reading at all from the TPS, supposed to be 0.55 volts or there abouts. Car is putting out a code 22 only.

Verify that there is a 5.0VDC reference voltage between the 'A' and 'C' terminals of the TPS. Without that, there will be no signal to the ECM.
