    Either you got something wet or maybe just a coincidence. Before going to a dealer, go to Autozone and have them read the code(s) for free.

    Kind of hard to tell you what to do if we don't know what the code is for. Borrow someones code reader or take it to Auto Zone.

    You could disconnect the battery for like 10 minutes on the positive side of the terminals. Then again, im not sure, but i think it resets something in the computer and and the next time you go to inspection you might fail.

    Cover up or remove as much as you can when cleaning the engine...cover the maf with a plastic bag or remove the lid/maf/bellow and block the TB opening, cover fuses...etc

    It would be a better idea to actually see what the code was instead of ignoring the problem until it takes out a few other components with it. But what do I know.

    Its under the intake manifold. Its most likely rusted and needs to be replaced.

    Is there not an outside connector for the wire.. the machanic said there is a slight chance that water got to the actual sensor and probably just got the connector wet..

    There are two knock sensors under the intake. The front one has a connector to the back one (under the intake) then the wire for both goes to another connector behind the intake on the passenger side.

    Edit: Weird, site reversed my lost two posts.
