psu_Crash Posted September 10, 2008 Report Share Posted September 10, 2008 The throttle body I have is off mustang GT and it came with a TPS. What order are the 3 pins on this sensor. I know there is +5, ground, and signal. Just need to know what is what? Thanks! Link to comment Share on other sites More sharing options...
travs87tsi Posted September 10, 2008 Report Share Posted September 10, 2008 To hook up your throttle position sensor (TPS), disconnect the TPS, and use a digital multi-meter. Switch it to measure resistance. The resistance between two of the connections will stay the same when the throttle is moved. Find those two - one will be the +5 Vref and the other a ground. The third is the sense wire to the MegaSquirt® controller. To figure out which wire is the +5 Vref and which is the ground, connect your meter to one of those two connections and the other to the TPS sense connection. If you read a high resistance which gets lower as you open the throttle, then disconnected wire is the one which goes to ground, the other one which had the continuous resistance goes to the +5 Vref from the MegaSquirt® EFI Controller, and the remaining wire is the TPS sense wire.
