*Update* on submerged TJ

Thanks guys for all the advice.
We got all the water out, luckily the air filter stoped all the dirt, but now the check engine light is on.
I scanned it and it's throwing codes:

P0505 - Idle control system malfunction
P0121 - TPS switch A range/performance problem
P0123 - TPS switch A circut high input

Obviously it needs TPS needs to be replaced, but what is the P0505 referring to? The idle is going up and down a lot. Also, it doesn't seem to be shifting as smoothly (5 speed).
Thanks,
Chad

I would replace the TPS, reset the computer and see if the other code clears up as a result. If not, I would look to the IAC.
