2004 T/C Check Engine Light

I have a 2004 T/C and the check engine light just came on (solid not flashing). The service manual says that if not flashing it is ok to drive, however, I can hear what sounds similar to a pump or servo frozen (light hum). There is no noticable driving differences. The sound that I hear can be heard "winding down" when I shut the vehicle off. This noise could have been there for ever and I just haven't heard it because I haven't had a reason to listened for a problem. Gas cap is not damaged. It just started raining here in Az., could it be a wet emission sensor? Any ideas will be appreciated.

Please help! No code when pushing and holding the trip reset or cycling key.

go to an autozone or advance auto part and have them pull up the code; you won't be able to find out what the code is unless you have a scanner yourself. As far as the humming sound you hear, that's just the fuel pump; it's normal doesn't mean that it's about to quit on you.

If you need further clarification, I created a thread in the Intrepid forum to help people w/ OBD II cars understand what the codes mean and where to go from there. Here's the link: http://www.automotiveforums.com/vbulletin/showthread.php?t=355082

The hum is probably just the cooling fans running . I have a 2004 and the fans seem to run more than my 96 Voyager did . Possible you left the gas cap loose the last time you filled up ? If this is case it should go out in a few starts . When filling up make sure the cap clicks at least once .

Thank you for the help! I appreciate it very much. The thread that was recommended is great!
