Have you already ohm and visually inspected the wires ? Seems highly unlikely it would be a PCM issue and if it was the PCM it wouldn’t be that code....it’s the wires, connectors, or sensor

replaced the sensor with oem. no change. ohmed wires, limited electrical knowledge here. thinking short in wiring, troubleshoot guide says it could be a pcm.

It'll physically run and drive. No charging system will be your main concern though.

it will start and run, but. it may die and start backup 2-3 times before you can get up to speed. seems like if i am heavy on the throttle it dies, go easy and it picks up speed.
