afc throttle position problem

[hellraz0r1337]

well i have the old afc and everything is hooked up right and has been double checked afc turns on correct and the afc is in perfect working condition(allready sent it out and had it checked). Now this brings me to my problem the afc isnt reading throttle position right, it will read 0% even when im 3/4 throttle but when its floored it reads 100% the afc will read 90% and lower if u go from full throttle to letting off a lil it will read some of the way down then go to 0%. Sorry for the book ### help im thinking tps but i want to be sure

Try this:
Check the TPS voltage closed and at WOT.
Make sure you have your AFC settings with the throttle arrow pointing up.

ya its on karman 4cly with the arrow pointing up when i goto sensor check it stays at 0.75v then all of a sudden shoots up to 4.800(full throttle) and then on the way down reads a lil and then goes to zero so its the tps u think ?
