TPS % on Scanner

Post by superstingray77 »

I have searched but not located a good explanation of this:
Why does my TPS% on the scanner show 16.7% at idle and only 77.8% at WOT?
Using a MOPAR sensor, TV(trans cable) is not restricting my throttle any, and linkage has full throttle range.

When you consider that a TPS of 100% is the reference voltage of ~5v, your idle TPS is ~0.83v and WOT is ~3.89v and those are right on the money.

Perfect, 505 performance tried to tell me that the idle should read 0%. Just didnt sound correct to me as I was following the same logic as you guys.
