MANY times systems are scanned & there codes present.
How long have they been there?
Do they (codes) mean anything?

In most cases the codes mean nothing.

That is why many shops make BAD diagnosis, they think that
any code is most likely a problem & 95% of the time they aren't.

Oil changes are simple on that car & you can save $$$ by doing them yourself!
