I never saw this before, but I now see that it has this.. and it looks like it's yellow... is that thing a light? What is that thing? I only need to check the codes if the actual red CEL is on, right? If I do need to check them anyway it is under the passenger kick panel and you just jumper it like you would on a chevy?

 

Maint Req is a remider that you need to have "some service" done. On this gen I think it is a simple "counter" that reminds you to change your oil.

 

Poorman is correct it just changes color every 3,000 miles I think. If you look right next to it on the cluster there is a little black button. You will find your key fits perfectly into the button and will reset it to green.

 

I think it turns yellow, at a certain mileage, then red, after additional miles. It's only a reminder to do the maintenance, so nothing is wrong with the car. The Check Engine Light (shaped like an engine) would mean there is a problem, and there are codes stored. Like he said, push your key into the little slot next to the light, and it will go back to green.

 

This has started happening to my car, and panic ensued until I started reading these posts.. Thank you for calming me down lol.. I'll try that trick tomorrow...

 

For your 2003, it's a slightly different reset procedure. I'll look it up and post it for you; but, it is in the owner's manual.

 

This is for the 2003 Accord, see image.

 

Thank you! I don't have an owner's manual as of yet, my car didn't come with one.

 

Update! The reset worked! My light is off! And my stress is gone! .....until next time...lol
