Check Engine and Traction lights turned on after driving through water on a flooded street?

I drove through water on the road when the streets were flooding in my neighborhood. Immediately afterwards the check engine light and the traction light came on. They turn on and off intermittently but are on longer than they are off. I have replaced the oxygen sensors on the vehicle and no changes in behavior. I have replaced the accelerator pedal sensor and there is no change to the vehicles behavior.
