Hello, My tps has 2 sensors on it one 3 pin and a switch to activate it. I've tried hooking up only the 3 pin to my Speeduino without any readings. I also tried feeding the switch 5v to try to get something out of the tps. I tried reversing the polarity and still nothing. Do you guys have any ideas on what I could try to get this thing to work? The engine is in a Nissan 240sx with a wiring specialties harness.

have you seen the wiki on how to find out which tps pin is which?

Have you referenced a factory service manual for pinout ?
