Check Engine light came on in May. Dealer couldn't figure out why, reset code, and I was on my way, after paying $89 diagnostic fee.

A couple of weeks later, it came on again. They suggested "maybe you didn't tighten the gas cap enough". Hah! I've been doing a minimum of 5 clicks since I got the thing! Got a new gas cap, they reset the light, and went on my way.

Guess what illuminated my dashboard again yesterday? Dealer _still_ had no clue "all tests passed". They reset the light, and at least they didn't charge me the diagnostics fee again.

But, based on my experience, I'm expecting this thing to come on again in the near future. I could do what the Car Talk guys say ("put a piece of electrical tape over the display so you can't see it"), but that makes me uneasy.

Based on the fact that it is a recurring same code, and I've done the first steps of getting it diagnosed and getting the gas cap changed, what ought I look for next? (Besides a new mechanic, perhaps?)

Thanks in advance.

You have plenty of recourse since you had the Dealer work on it. If the Dealer claims to be stumped ask to speak with the District Service Manager so you can explain the issue to him/her. You need to force your Dealer to elevate your issue within Honda's service organization until they find the service tech who actually knows how to run diagnostics. You may have to be rather persistent.

Thanks. Do you think the dealership would appreciate it if I printed that all out and waved it under their noses the next time I go in? :-)

I'll get to see what printing out the discussion will do. Yes, the check engine light came on -- again. 8 days after I had it in to the dealership, where "duh?" was the answer I got to what was causing it.
Grumble.

Hondas are supposed to be reliable! My Civic (which I had for something like 14 years) never pulled this nonsense.

For the _fourth_ time, car got taken to dealer. This time, I had to leave it overnight so they could start with a cold engine.

Same code came up, same "smoke tests" were done, mechanic is baffled as to why code is coming up, and no one knows what to do. "ATP" (all tests passed) Husband is worried about passing inspection in a couple of months.

I _wish_ we could find a definitive answer for this!
