Thread: TPS Issue

I am finishing up my swap and ran into an issue with my TPS. When the car is idling my TPS voltage is 4.7, which is obviously not right. I swapped sensors and the same thing happened. Now something that is weird is that when I press the gas pedal or turn the throttle, the voltage goes down... Before tearing into a harness, has anyone else had this issue? I am thinking about swapping a DE throttle body on, but wanting to see if anyone else has had this problem.

Tps has to match ecu. What ecu you running? Usually u gotta swap the I'm over from the old de

I have a Calum Basic. I thought those TPS sensors were the same as the roller rockers.

sounds like your wires are reversed

Tps is diff for the rr than lp de or hp de

dude, your wires are reversed... repin the wires on the two ends. keep the middle constant.

And that exactly what I think is the issue. I just found out the harness was on a gtir engine.

lol

So on the tps the top wire is power, middle is singal, and bottom is ground?

And that was it. The power and ground wires were swapped. Connected the right way and it runs like a champ.
