won't idle

OK then same exact set up. +5V ref, -5V return and a signal wire out. The sensor is a variable resistor and the voltage should smoothly swing between 0 and around 4V with key on engine off and sweeping the throttle back and forth. Same drill, check power, check ground, check output voltage.

The P0122 code is set when the TPS sensor output drops below 0.1V so we have not reproduced the fault yet.
Do the same TPS output measurement with the engine idling and try some slow smooth rpm changes.
Measure the voltage at +5V ref and -5V return with everything connected, once with key on, engine off and once while idling.

Back to the map sensor issue for a second. I still have the fused jumper across 5v ref and sensor output. I figured I try to clear the p0107 code map sensor low voltage but it's not clearing. I checked voltage across 5v ref and 5v return with key on engine off and I have 5v like I'm supposed to. But when I start the engine it's dropping to 0v. This same exact issue is happening with the tps also
