I would say you got a sensor wet when you washed your engine, that is why the engine light is on. The car's computer is picking up a problem in the system. Also you could have made the drive belt slip by getting it wet too. When washing an engine you need to remember to cover up things in the engine before washing it or keep the water away from those places. Like the distributor cap, alternator and the air filter. Should have the car coded and it will explain the engine light.
