This is a "drive by wire" electronic throttle system that requires some very expensive diagnostic equipment to troubleshoot. It uses 2 TPS sensors and then are incorporated into the electronic throttle body which is not cheap so you don't want to misdiagnose this..

Unless you feel like rolling the dice on a $600 part, yes, that is what i would advise.
The P0443 has nothing to do with that issue. That another problem in the fuel vapor system.

I just looked and the throttle body is more like $300 but still an expensive gamble.

That indicates a problem in the purge control circuit that also need to be diagnosed electronically.
