I would like to wire this toyota TPS to my megajolt, its a 3 wire sensor, is there a way to find out which is the +ve -ve and the ref? I have no info with this item.


Thanks

TPS

cut and paste from a Ms site. ive used it to do a few sets of bike carbs.


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."

Thanks, will give it a go.

Worked great, thanks a million
