check engine light is on

What is your question?

Ive had my truck in to the dealer twice already. First the check engine light come on with the wrench light. The ABS and brake lights are also on. Ford originally told me that it showed a 2106 fault which was the throttle actuator. Is this the throttle body or the pedal assembly or both? With the ABS light, it showed faults on all three sensors and they didnt dig too deep into that. The last time I washed my truck, I wanted to check fluids also and ended up washing my truck with the hood open. Could I have gotten water on the sensors, or in the pcm?
