TPS reads WOT @ 5% Pedal Movement

I posted in tuning tech, but haven't gotten any responses.

Just hooked up the AFC NEO. Everything functions as it should with the exception of the TPS reading on the AFC. With the pedal out it reads 0.035ish V and then I would barely hit the throttle, it flashes up to 4.75V. When the TPS is unplugged it also read the 4.75V. So it is basically reading WOT as soon as I touch the throttle.

I tried another working TPS and it does the same thing. While I had the TPS loose I rotated it to see if I could get different readings. And I would barely rotate it and it would either read 0% or 100% throttle.

What would cause the TPS not to be able to output in betwen 0V and 4.75V and just go to one extreme or the other?

im sure you have done this but just to be sure...did you program your tps by selecting the mode on the neo and then holding the pedal in and letting it out? i remember i had to do that with mine and it worked.

Yep, I did that. Thanks though.
