If those faults have the same source, it might indicate a wiring harness
I suspect the regulated Sensor power voltage lead. Like the 5v on EECIV.
Off the top of my head, I would try this:
Connect a VOM (needle type would be best) to the center lead of the TPS. To
a solid engine Ground. Verify the voltage is stable and proper during
Do a tap and tug test of the entire engine wiring harness all the back to
the PCM connector...While listening for change in engine and watching for
blip of the needle.
If it's the 5v, needle will drop.
Also Check Wiring harness ground points and engine to chassis grounds.
