Check Engine - Why 3 Trips?
My Check Engine light came on today. Scared the hell out of me. First I thought it was the spark plugs (no TSB yet). Then I remembered reading something on this site (thank God for this web site) about the gas cap being loose. Sure enough, the thing was loose. I'm assuming this is what caused the light to go on. (Yes, I read the previous posts). My question is this. Why does it take "3+ drives" to get the check engine light to go out? And how is a "drive" defined? I drove around the block, shut the car off and drove again. Then repeated the process. 3 drives...light still on. Does 3 drives mean after the engine cools? Is there a distance variable? Any ideas?

In the VW/Audi world, we have a tool called Vag-Com that emulates a dealership scan tool on your laptop. You can check error codes, reset check engine lights, monitor and log engine parameters (boost, timing, injector duty cycle, intake temp, etc.), change power lock/alarm settings, etc. It costs $199. Isn't there something similar available for Hondas?

That's scary. What if it was on for another reason?

In my case it took 2 days and 5 15-miles trips separated by 8-9 hours to get rid of that light. Be patient and don't take out any fuse!!!!

Been through the same routine. First time the dealer reset it. Next time I just waited for it to go out. Took 4 or 5 "trips." Loose gas cap is the cause due to rachet mechanism I guess.

Pull the ECU backup fuse for 30 secs. It's the 3rd one down from the top of the right bank of fuses under the driver's dash. It's the 7.5 amp one.
As for not pulling a fuse, if you're pretty sure it's because of the gas cap, this'll save you driving around and around and around. If it's something else, the CEL will come back on real quick anyway.
