I very lightly pressure washed my engine in order to get the salt off of it. I covered the distributor, coil and throttle body with plastic bags and rubber bands.

Now though I'm getting an inconsistant Code 25. What gives?

The engine isn't old (replaced about 18k miles ago) so I shouldn't blown out any gaskets. Hell, I didn't really even spray the upper part of the engine that much except to get the soap off. All of my hard corps sparying was down around the radiator support and cross member.

 

25 Manifold Air Temperature (MAT) sensor or circuit / high temp.

 

So it could be that it just got wet huh? Maybe it will go away after it dries up some?

 

Gunny try disconnecting power from the ECM or disconnecting the battery for 5 minutes. It will go away.
