Hi,
Looking at the codes, the first thing I would suggest checking is the gray wire between the PCM and the throttle pedal position sensor. So, go to the TPP sensor and disconnect it.
Using a voltmeter or multimeter, check for a 5v reference.
The PCM is in the left rear of the engine compartment, so the wire may have been damaged, pinched, or disconnected.
Let me know what you find.
Take care,
Joe
