Has anyone else check their Throttle Position Sensor with a volt meter? From data posted around the net (ie: RPI, and other owner) the voltage at idle should be around 0.3-0.35 volts. My 94 Disco reads 4.6v at idle, and goes to zero at wide open throttle (WOT). There is no fault codes, nor running problem (as it seems). Anyone checked their idle voltage (red and yellow wires)

Thanks,

not sure how you are checking it but you should get about .3 volts at idle and 4.5 at WOT. sounds like you got it backwards.
why did you check it if it runs O.K.?

That is what I read... 0.3 at full close and 4.5 at WOT. My is ass-backwards, and the truck runs fine. Did you put a volt meter on those two wires? I wonder of certain model is like that (ass-backwards). I guess my TPS could be bad... but it shows no synthoms.

If you feel like checking your voltage, please post the result.
