TPS unplugged, makes no difference ? Throttle Position Sensor

[tiksie]

As per title,

I've noticed that when I take off the plug on the TPS (throttle position sensor) nothing happens ? The cars idle doesn't change, it doesn't show up any errors ? Accelerator actually feels a bit better though (revs don't drop down so quick when accelerating in neutral).

Is this symptoms of a faulty TPS ?

Thanks

Doesnt sound right, worth checking the TPS setting.

I've already tried that, but nothing happens on my multimeter :S

try removing it and cleaning it... just some points. if it wont work just replace it

The thing is though, the ECU doesn't recognise it as being a fault ? I would have thought it would flash in the diagnostic mode of being faulty, but even when unplugged it makes no difference ?

im not sure if it gives a code without TPS..if you want i can try it on mine.

the ecu diagnostics is very very basic, i wouldnt trust it, do things the old fashioned way would be the best

disconnected tps equals half throttle on a non-automatic tps.
doesn't matter for idle or half throttle, only on full throttle but the ecu will not throw any errors in most cases. It most probably only will on > 60 km/hour and more than xxx rpm.
