You can narrow down the root of the problem by following this procedure:

senstive talaga mga sensors ng honda. you can try resetting the ecu first, if no go then proceed with the self test above. if you want to be accurate just drop by to a honda casa for the diags via computer then have it serviced outside.they will give you a print out malamang dirty or defective sensor. pero if you want to DIY , then count the long and short lights flash during the diags then refer to the manual which sensor is the culprit

You cannot do a self diagnostic by yourself unless you are a trained technician. Check engine could be anything and no one could help you here. Bring it to the honda dealer they know better and they have the machine to pin point the problem.

I beg to disagree. You can google for the shop manual. That's the same manual the pro techies are using and I can assure you that almost anyone who can read it will be able to at least diagnose what's triggering the CEL. Of course, you probably won't be able to fix every problem that pops up. But at least you'll have a general idea of what's wrong so you'll be better informed when the mechanic gives you the repair estimate.

For instance, if the CEL says it's the O2 sensor that's at fault, you'll know that the mechanic is probably running a number on you if he says that you should replace the MAP and/or MAF sensors as well. Unless of course if he can prove that these parts are already beyond their service limits (parameters of which are also stated in the shop manual).

In other words, there's no harm in figuring out what's wrong and try to see if it is field repairable (ie. loose or corroded connection). You only need common sense and a bit of analytical skills and there's potential to save a lot of money.
