Is there a way to find out what caused the "Check Engine" light to come on?
If so, how do you get the codes and where can I find code information?

I have a 93 Honda Accord EX. The check engine light came on, but
everything seems to be running pretty smooth. I did put in a bottle of
Techron fuel injector cleaner several days ago, and wonder it this may
have triggered it.

Just not putting your gas cap on properly can cause a check engine
light to come on in some cars. If you do not want to take it to a
garage to have them put it on the computer to read the codes, there are
manuals on the market, like Haynes, that will tell you how to check the
codes on your car. Doesn't work for all models, some need to be read by
a computer. The manuals will give you all the instructions, but
basically, you just unhook your battery for a few minutes, hook it back
up, start your car and watch for the number of flashes from the Check
Engine light then check the book to see what it means.

See page 15.

Nope.

Ok, I have checked out the code.

The only code that flashes is 43. My Haynes manual only goes up to 42.
Anyone knows what this is?

I did clear the code after checking it by pulling the fuse. This morning
on the way to work, the check engine light came on again a little over 20
minutes into my commute. A little later, I stopped, turned the engine
off, and restarted. The light didn't come on. I am sure it will probably
come on again on my way home. (Has done this for the last 3 days.)

Code 43 is a problem with the fuel supply system.

Have fuel pressure checked. If OK, it's likely the oxygen sensor.
