My car has the check engine light on. Is there a way I can check the codes by jumpering a couple wires and reading the flashes, or do I need an OBD2 scanner to do the job? Thank you.

WARNING!!!: USE AT YOUR OWN RISK.HOW TO OBTAIN TROUBLE CODES MANUALLY (6Th Gen Accord - V6 & I4)1) Find the Data Link Connector (DLC) located under the instrument panel in the driver's side.2) Jump terminals 8 and 13 by connecting them with a wire/cable

DATA LINK CONNECTOR (DLC)3) Turn the ignition key to ON[/b] and observe the "CHECK ENGINE[/b]" light. It will flash the trouble codes. For example: 2 long flashes, pause and then 3 short flashes = 23 = P0325 = Knock sensor circuit fault. One short flash = 1. One long flash = 10. If there is no trouble codes, the light will not flash.Flashes.....

HOW TO CLEAR TROUBLE CODES [/b](after fixing problem)1) Remove ignition key (OFF)2) Locate fuse panel on passenger's side (open door)2) Remove fuse no. 13 (7.5 amp) for 10 seconds, and then place it back in.

 

Awesome info!! Thanks!

 

THIS WORKED!

I had got my car serviced at AAMCO for tramsmission problems (second gear was shot). After i got the car back, i noticed my Check Engine light was still on and then after a couple of days it would not start in the parking lot... then all of a sudden it started. This happened two more times before it would no longer start. The started would click once, but that's it. I purchased the CarMD device, which gave me two trouble codes - P0420 and P1739. Anyway, to make a long story short, after searching through tons of blogs and forums (and trying the basic stuff - checking fuses, gas cap, trani fluid, etc. nothing pointed to anything), so I thought of trying to clear the codes and seeing if that would do anything. That's when i came across this site, and saw your note about HOW TO CLEAR THE ENGINE CODE by pulling out fuse #13 (labeled Clock/Backup) on the passenger side. I did it and lone behold that cleared the code... and guess what... the engine started right up! Neither code has returned, so there';s a good chance that the idiots at Cherry Hill NJ AAMCO did not reset the codes when they finished thur work. THANK YOU

 

I just did this too and it works awesome. Check engine light on, P1259 code, found I was low on oil, added some, reset the light and whamo, back in business. Now I just need to figure out why I was low on oil. Maybe because my awesome 99 Accord has 140K miles on it and must start burning oil at SOME point.

But it still runs like a CHAMP. It has NEVER malfunctioned except for piddly stuff like the blower. I've been through so many tires and brake pads I can't count... If my Accord was a woman, I'd marry her and father her children. Don't tell my wife...

 

Wow this is an amazing piece of info...
But OBD 2 CAN code readers are very cheap now. You can get one for $20 from Amazon. I would just use them for most accurate result. Plus they let you clear the code with ease. I bought one of these scanners and was able to use it for my 2005 Accord hybrid.

P0420 is your catalytic converter, if it comes back refer to this video.
