Post GM early OBD2 TPS PID
on: October 30, 2018 (GMT)

So I have tried the throttle position PIDs and am getting no data from them. I am trying to diagnose a strange and intermittent issue and I want to correlate throttle position with some other variables.

Not having either TPS percentage or voltage is making this task very difficult.

My experience is with diacom+ and Tunercat. This application is still new to me and I am still learning.

Searching for a late 90s GM TPS PID has not proven fruitful.

Thanks.

Have you tried 221143?

Well, not sure why it wasn’t working, but tp manifold is recording a value for me now.

Still would like a voltage since that is what I’m used to plotting.

Nearly everything on a GM is 1.5v or 5v reference.

Have not. I have only made a couple custom PIDs and deleted them both because they were not useful. Tons and tons of stuff I don’t care to see. If I was getting an SES then I’d go down that road more. It’s not setting a code so I can’t really determine what is happening.
