Did you reverse the TPS when you install it? Fully closed throttle should read around .45-.5V and should not exceed 1V at wot.

Re: TPS Problem: Inverted Voltage (fox297)

there's no way i could plug the TPS backwards, and i have no ecu codes at all.

here's a diagram of the wiring:

_____/ \_____
------------------
| 1 | 2 | 3 |
------------------

1 - Ground
2 - Postive
3 - ECU 5v

i used 1 & 2 to adjust, but i have no explanation for the reversed voltage
