I went to check the throttle position sensor on my SPi and it doesn't have one! I thought they all did?
I've been having problems with the idle speed but I seem to have sorted it.
It's a '94 sprite, did the early ones not have the sensor?

I thought that only the really early ones had the sensor. My 94 and 95 both dont have one either..i think. Are talking about the throttle position sensor that would tell the ECU to what degree the butterfly is open or the switch that some cars had that simply told the ECU that the butterfly was at what?

I mean the sensor mounted at the top of the accelerator pedal to tell the ECU when you put press the pedal.

Right. I know that the few wiring diagrams that I have found for the SPi do show a circuit for that but from what I was told, they only used them on the really early SPi's. The switch at the pedal was just to tell the ECU when the pedal was at what (wide open throttle) and nothing else.

Indeed, according to the Sykes Pickavant documentation, it was removed in '93.
