wats up everyone.. so i have an issue.. my car is throwing a P0121 code for the tps sensor.. it says switch A/ low voltage.. now wen i connect to my evoscan it reads 9.1.. is the tps supose to read 13. without stepping on the throttle.. and would it throw a code from being a bit of scaling.. or is it just a bad tps.. thanks..

 

13% tps is normal when you're off the gas.

 

I had a bad TPS on my VIII and my Voltage was 0.25V at ideling (very weak) RPM was fluxing btw 400~2000 rpm!

replaced it $$$, cleared the code and everything was back to normal.

apperantly some throttol body cleaner must have got into the TPS when i was cleaning the throttol body, (that is a no no)
