Quite a few weeks ago I drowned my car in a rather large puddle somewhat lake sized. Being that my car is lowered, it suffocated and died. After letting it dry out for a day it finally started back up, but with error codes of course. After having the codes scanned it seems none of my O2 sensors are left and they all shorted out. I would like to know the estimated cost of having them replaced professionally or the difficulty of doing the job myself sans garage. I imagine I am not the first person to have this problem. Looking forward to some advice. Thanks,
Brian

Unless the exhaust got submerged so deep that water got past the cats and almost into the engine I'd suspect a wiring issue elsewhere.

It was actually above the bottom of the doors. Just inbetween the skirts. Not high enough to flood the car but very very close.

the o2 sensors are located on top of the cats, so the water would have to be up to your windows to be drowned

^i think there are two that are located on the bottom of that cat.

Drive for a while to burn off residue moisture in the cats.. Reset with an OBDII reader. If it comes back right away, check connections.

There are two upstream, two downstream (top and bottom). Upstream are actually Air fuel sensors, people call them o2 sensors though.
