Low WOT TPS Voltage
My closed TPS is fine, my WOT is only 3v. The pattern when opening the throttle is smooth and linear. I can change my WOT setting in the C950, but my question is.... is my TPS going bad? Bad already? or just a weird fluke that will be fine after I tell the ECM what WOT is?
Thanks

You know..my TPS voltage was the same..but mine wouldnt go over 4 volts.I replaced it and rechecked it and did the same thing.So I was thinking maybe the throttle cable was stretching..Closed is about .5 and WOT is around 4.50 I think thats roughly for every TPS.If I mash the pedal into the floor board it will go higher but not much.

What about when you open the throttle blades 100% by hand? What does it read then?

Good idea...I think it was the same ,but looks like tomorrow I will be checking that.I havent checked it with the new TPS in it..so cool thanks for that info.Then that would give me a better idea on the cable.
