Lewis Posted December 20, 2022 Report Share Posted December 20, 2022 Hi to the community. I have converted my Miata to itb setup with the 20v blacktop throttle bodies. Today when I started the car I couldn't get the tps working right. Miata has a 3 pin connector, Toyota has a 4 pin connector. I found the +5v ref, gnd and signal and crimped them to the Toyota 4 pin connector. 1 unused pin. The pin out for the Toyota is the attached picture if I am not mistaken. Well it does not work, either I get 100%full throttle even with the tps disconnected(only the connector) , either I get a very very slow rise with the pedal to the floor and when I release the throttle it goes to 0 and after a second to 100%. I have tested 2 tps sensors. The car previously was a single throttle body with the original plenum and run flawlessly. It was tuned by me with alpha N due to the map signal being erratic. Has anyone any clue what the is happening? Quote Link to comment Share on other sites More sharing options...
