Answer 1

Park it in the sun for a few days, you might get lucky! Sensor, relay, wet wires? Good luck!

Answer 2

Park it and hope someone steals it. Hopefully they wont bring it back

Answer 3

My guess is the ECM went for a swim, and will need to be replaced and reprogrammed.

Of course, it would help if we knew what codes are turning the CEL on.

Answer 4

I'm assuming you're in The US so I'm not familiar with the car, that is, is it diesel or petrol? First thing is check the position of th engine air intake and could it have been below water. You may have pulled water into the engine. If the air filter is wet that should give you a clue. If you have it could be terminal for the engine , particularly a diesel. The only other thing is it may be electrical. though the water would have to be deep to affect those parts.
