2003 Accord V6 Check Eng light
 

Check Engine Light (emissions light) came on this evening while driving to dinner. I have 77k miles and have had to replace only ABS and TCS wiring (under warantee). The nearest dealer is 45 min away. Is there anything I can check other than the Gas cap? I re tightened the gas cap, but doubt that will do much good. Is Autozone able to read Honda Engine codes? Still runs fine, but I want to get the problem addressed before warentee goes out. My wife also had a wreck about 4 months ago. Everything was replaced w/ factory parts and has run fine until tonight. Any help would be great!

So I disconnected the Neg cable after tightening the gas cap, the light went off, then drove around the neighborhood getting the rpms up and gas through they system...light didn't come back on yet. Maybe that's all it was...man that things fast (compared to my toyota truck)!

next time the light comes on.

Find the Data Link Connector located under the dash panel on the driver's side.
Jump terminals 8 and 13 by connecting them with a wire/cable.
turn the key to ON (dont start)

pins go left to right... 1-8 on top, and 9-16 on the bottom.

long flash = 10, short = 1.

So does the light come on too often? For nothing serious? My wife said it did not come on again today, I guess all is well.

:bowdown: OH! this info can be very handy in the future.

Just a quick question: is this for all 2003 accords, 4 cylinder and V6 models?

Thanks

you might have an intermittent problem which is why the car hasn't thrown another code yet. next time get the code before erasing it! autozone can pull the codes for you for free if it happens again or you can jumper the data link connector as jani 5 stated.

its for most hondas

light cam back on again, I'm cleaning the KN filter for the first time in a year or so, needed it, maybe that will help. Can auto zone get the codes? I've had them tell me they can't before, can't remember if it was my Toyota or Honda. Guess I'll find out. Thanks so much for the listing of codes! I'm getting it back to the shop to have some issues worked out from the major repair a few months ago, will have them check the light as well. Thanks again!

help me out here. It flashed 11 slow times, and the 7 fast flashes, what does that mean?

11? :eek3:

Ok, I'll go count again, please hold...

I swear I can count...right when it turns to "on" (not starting) it flashes very fast once, not counting that... then in pauses, flashes 11 distinct times, pauses, then flashes fast 7 times. pauses and repeats.

guess i'll run by the zone tomorrow, maybe their scanner can tell me.

Problem solved
 

Autozone said it was code P2422 for EVAP solonoid stuck closed, pressure was building up the tank and not releasing back into the eng. I went ahead and bought a manual and located the purge valve in the eng compartment. All I did was mess w/ all the plugs/hoses on the EVAP canister under the gas tank and pushed the purge valve a few times w/ the eng running and warm. Reset the light and It hasn't come on in 200 miles w/ several trips...guess there was a loose hose or something. Thanks for the help.
