[email protected] Posted February 3, 2021 Report Share Posted February 3, 2021 I have wired my tps and calibrated it. Tps voltage is high at closed throttle and then low at wot. It seems backwards. For example when I press F12 for runtime values with the throttle closed I get 2.56v and as I bring it to wot the voltage decreases. It is a four pin tps off a Toyota Altezza. Pin 1 on one end is sensor ground. Pin 4 on the far end I gave 5v from the ecu bottom row 3rd in from the right. Pin 4 I wired to the AN Volt 2. I upgraded the Link G4+storm blue to the latest firmware today. Maybe it need to configure something. Why does it seem backwards. I would expect low voltage at idle and close to 5v at wot?

[email protected] Posted February 3, 2021 Author Report Share Posted February 3, 2021 Ok. 15mins later I reversed all the wires from top to bottom. Boom! it worked. I had the ground and 5v inverted and the idle and signal inverted. Great to have a win. Quote Link to comment Share on other sites More sharing options...
Vaughan Posted February 3, 2021 Report Share Posted February 3, 2021 It doesn't actually matter which way around the voltage slope is as it is corrected for in the TPS calibration [email protected] 1 Quote Link to comment Share on other sites More sharing options...
EvocentriK Posted February 4, 2021 Report Share Posted February 4, 2021 It may not for many, but it does for an EVO CT9A, FYI. The high voltage triggers the ACD pump into an ON state. Quote Link to comment Share on other sites More sharing options...
