You may have a wiring issue . It's reading high voltage so I would think the wires may be shorting somewhere . Time to start checking/tracing/testing wires , especially around and close to heat sources

Also, check your grounds on the PCM as well as around the TPS & Clock spring wiring. Make sure they are good and clean.

Ended up being a broken clock spring causing TPS issues through a shared ground. Anyone know where to locate a speed sensitive clock spring these days?

You mean on your steering wheel? How was that affecting your TPS?

the clock spring uses the same reference signal as the tps. I disconnected the clock spring started right up and ran like a champ.
