i believe my tps is going bad what wire do i probe inside the cabin so i can hook up my multimeter wanna monitor it while im driving says red/black wire on every single diagram i find but when i probe it i get steady low voltage it doesn't vary when i open or close the throttle. the only red/black wire i found was the furthers plug on the right side top row that is if you were looking at the ecu connections directly in front of you

 

The odds of a tps going bad is so astronomically low it cant really be bad. The signal wire is normally the middle wire. One will have 5v the other will have ground.

 

i know the correct wires for the tps its self. im getting intermittent tps code, thought it was wiring but doubt it, feels like a dead spot not all the times, bogging bucking backfire type **** all i have to do is go past that dead spot and it takes off, this dead spot doesn't always happen tho so i don't get it. i get reference 5 volts good ground at the plug and signal wire reads correct doing it by hand can't make the dead spot appear only happens mostly while driving as well. i just want to be able to back probe the ecu tps wire so i can monitor it from inside while im driving i want to see the dead spot before i go and replace with a new one.

 

says d11 which is the furthers plug to the right top row pin 11 plud "D" that is if its right on this link

ok these are my under hood tps location voltage closed 0.48 volts wot 4.42. now i back probed the red/black it was correct just thought i was probing the wrong one because of these readings 0.38 volts closed 4.42 wot volts i need to drive the vehicle around that will be tomorrow morning

 

If it tests fine then its fine.

Must be a wiring or connection issue
