24x TPS volts are high

[kris72079]

Simply meter from pin 28 on the blue connector to the gray wire in the tps connector. It should be a straight run of approx. 6' or less so you should see a resistance of 0.2 ohms or less if its good. If its a good run then check voltage with KOEO, if its more than the prescribed 0.4x vdc at closed throttle or 4.7x vdc at wot suspect faulty pcm or shorted wiring. I have a 24x conversion pinout if needed.

Unless the harness was put together wrong which eficonnections seems confident it's not the problem I don't see any issues. Can't find a bad wire. I'm half tempted to buy another pcm and see if it works.

If you want to spend some money,I would buy a used 411($50-100), don't liscence it and see if tps works correctly.
If it does then liscense it, send back pcm to x tuner.

I'm thinking about doing that but I'm gonna test the ohms like kris said and also realized where my issue could be. The micro edge controller taps into the TPS wire probably where my issues at. It takes me some time to do it though cause the cars not at my apartment. Gonna try and get over to it tomorrow night

Easier. Meter voltage, then disconnect microedge. Does voltage drop to correct voltage???

If you aren't using one of the other 5v reference pins just run a temp wire to the tps and see what happens cause it doesn't matter where the reference voltage is coming from.

I've had this issue before when setting up my dfi. If I recall correctly I had 2 wires switched at the pcm (I believe it was the reference and signal wires). I would trace them back from the sensor to pcm and see what you find

Well I got up before work to go mess with it. I checked voltage at the MAP reference it was 5.01 unplugged so I disconnected the microedge controller checked the TPS and it's working. That problems fixed and now I have another. Thanks for all the help sorry for wasting everyone's time for a simple problem. I put all the nitrous stuff on the back burner till I could get the car running right. I forgot the microedge hooked into the TPS until you guys mentioned pin 28 on the blue side and it hit me. I checked the TPS wire that went into the red side and didn't read or know where the reference wire came from.
