washing with a hose is one thing, pressure washing an engine is another. Engines don't mind oil and grease, it keeps the rust away! I'd crack open the covers of any electronic modules you can get to and let them dry out, maybe a little compressed air will help. Your ECM is under the hood right side by battery, I'd make sure that was thoroughly dried out. A good dielectric spray will displace any water and add a protective moisture barrier to electronics.
