So when customers bring their car to me, and say "can't you just hook up that scanner thingy and see what it is"....it's never that easy. I would take the code and print out a diagnostic procedure(sometimes 15 pages long) and go through it all to trace down the problem. So don't let AutoZone try to sell you parts after they read the codes, they don't know what's wrong, the code doesn't tell you what's wrong, it just gives you a place to start your diagnosis. Ending rant...sorry... AutoZone is only good for chrome valve stem caps, and maybe some tire shine...

Anyways, check fuse #15 under the dash. Then get under the car and look directly over the oil filter on the back of the motor. You will see a couple big connectors with lots of wiring. Check the wires very closely as they tend to rub on the bottom of the intake manifold and short out the rear O2 causing fuse #15 to blow and CEL to come on setting that exact same code, as well as others in other cases. Actually, I think Honda came out with a bulletin on this problem, yes it is THAT common. I've seen at least 12-15 of these same problems.

Im interested to see if you have the same problem...
