adjusting tps

trying to adjust my tps yesterday but i cant hit the spec. supposed to be 0.4V closed and 5V open correct?. i set it at .4V closed but open it wont go past 4V. is this a problem or am i ok?

It’s supposed to be 4V @ 100% and 0.4V @ 0%

0.5 close and whatever wide open. 4v is about right for wot.

0.35v-0.65v closed and 4.0v fully open.

4V @ 100% and 0.4V @ 0%

4V @ 100% and 0.4V @ 0%

its .455 not .4 and if you can’t hit that then its bad or your throttle plate is bottomed out low.
