Pull the codes from the computer, match the code to the troubleshooting procedure, follow the procedure to find the source. Repair the source, light will go out if that was the only problem. There are "monitors" or self test the computer runs the car through, if a problem occurs, it may not run all of the self tests until that problem is taken care. Therefore, another problem may exist.

The following worked on my 2000 Neon: After replacing what the diagnostic test said was bad, I disconnected one of the battery cables for approximately 30 minutes. I then made contact or touched the battery terminal with the cable battery clamp three (3) times and then connected the cable to the battery. It reset the computer.

You have to reset it with a OBC scanner :-)

The check engine light has nothing to do with an oil change. The check engine light is reset with a scan tool after repairing the failure that caused it.

Disconnect the negative battery cable for about two minutes and that should reset your check engine light.

You can reset the 2004 Honda Accord check engine light by removing the instrument light fuse. The location of the fuse can be found on the inside cover of the fuse box.
