Going by the DTCs you posted, I'd first check wiring between TPSs and ECM, particularly any grounds and connectors. If the wiring is OK, then I'd look at the TPS output and see if they are in sych with the plate. Wiring diagrams, harness routing, etc are in the FSM. Most OBD/CAN tools will allow you to look at TPS outputs (or ECM input).

Oops. That's the throttle pedal, so there's only one, IIRC. FSM will have details.
Double-oops. It is the positions sensors on the TBs. Either way, I'd check wiring and then sensor(s).
