Reading Check Engine Codes - NO DEALER OR AUTOZONE REQUIRED!
1. Jumper the service connector
2. Turn the ignition key to ON
3. Count the flashes on the instrument panel
4. Look up what the code means
the flashes will be a series of long blinks, a pause, followed by short ones. For example:
Long-Long-Long-Long-Long-Long-Long____ShortShort
7 long and 2 short, indicates a code 72, Cyl #2 misfire.
Once you've got the code, you should have a pretty good idea of exactly what the problem is. You can troubleshoot from there.
after putting my oil pan back on my 98 V6 accord I started it up and the check engine light came on. I used a paper clip and the above method and read a code 65... Secondary O2 sensor. Apparently while moving the exhaust to get to the oil pan I accidently pulled out the connector for the O2 sensor for the catalytic converter.
Reconnected it, reset the ECU and the check engine light went away!!
I didn't even have to leave my garage!!

I found it v6p.net while looking for a way to reset the check engine light.
Even though my asian honda tech would check it out for free I was happy not having to drive anywhere.
I'm sure it will help someone!

The good old paperclip and count the flashes works on most OBD cars. Just gotta find the documentation for what the codes mean.
