Check Engine Light - PO1456

Hi,
I was driving my 98 Accord when the "Check Engine Light" lit. I have a stick-shift and i just replaced not too long ago a O2 sensor.
This time i went to Honda and asked them to read the code and they came back with PO1456.
Does any of you know what this code is?
Thanks,
Filipe

P1456 is EVAP Emission Control System Leak Detected (Fuel Tank System).
My book with my OBD II Code Reader doesn't have anything showing for PO1456.
Aside from that if you went to your dealer to have the code read, why didn't you ask them to tell you what the code meant?

Brian,
Thank you for your reply.
Honda makes great cars. I wish they would make great professionals.
They wanted to charge $90 to check the code. I said i wouldn't pay and that i wanted them to just give me the code.
To be quite honest, i was quite happy to leave the place and i wish didn't have to look into their faces ever again.
Having said that it seems that i have to go back because this doesn't sound like something i could do on my own...
What do you think?
Thanks,
Filipe

Hi All,
Based on Brian's great tip I found that this is typically the gas cap problem. Now, the problem is if the gas cap was properly sealed. That means that i can have an actual EVAP system problem. Any tips on this one?
My car has been idle for long periods of time since I'm travelling most of the time. The car had been idle for 2 weeks and with a very small amount of gas in the tank. I was really "reving-up" the engine when the light came on.
Any help would be precious.
Thanks,
Filipe

The EVAP system is sophisticated enough that there is a unique code for pretty much each separate problem.

Who are you replying to? Me or the OP? I'm quite aware dealers and most shops now charge for diagnosis time. This, no doubt, because most mechanics are now dumber'n a bag o' hammers and take hours to figure out a prob. Back when my brother and I were wrenches, diagnosis time was on the shop and actual repair time was flat rate. Now, since the early 90's, it's screw the customer long and hard. Charge for diagnosis, charge for the inexperience of the mechanics, charge for whatever time it takes, be it 3 or 6 hours. Hell, charge for crapper breaks! Ever since Sears discovered the general public no longer knows the difference between a pitman arm and a valve cap and no langer cares to know, it's an 80 grit Trojan to the public ...no lubrication!
Hell, I expected this kinda crap from the dirtbags rednecks in Southern hillbilly burg filling stations in the South or last chance garages on trans-continental highways (Rt66) bach in the 60-70's. But, not from today's million dollar high tech dealers/shops. Silly me. The bottom line is still caveat emptor ...buyer beware! They'll screw you if you let 'em.

Doctors, lawyers, engineers: You name the profession, they all have this "work" ethic.
Why shouldn't mechanics be getting their cut?

Shucks, some surgeons don't know to check that the blood type of the organ they're transplanting is compatible with the recipient's.

If the market were truly free, then I'd say the market is a wonderful place.
Elle Knows many technicians who are smarter than doctors and lawyers.

For Quick code reading I have a cheap scanner. $600.00. Startup time is quick does all OBDII, some OBD1. the shops scanners; one is a older snap-on. 2700 new. The new scanner is a gyenises, the basic one is around 3000.00, with all the upgrades for almost all cars about 5000.00. My dream scanner is a Modis by snap-on 8000.00 for the options I want. Dealers have there own scanners that can do lots more on the brand car than the generic models. Most techs get paid by the job, and have to pay for the tools. There for we don't care if the customer wants a free service with there 30.00 oil change, we want to get that car out of there if there not going to buy anything else so we can keep trying to earn a living.

It's been many years since I worked as a motor mechanic. I wasn't aware the profession had degraded so much.

This is good information for folks here and customers in general to have.

That's another, what, like $3000 right there for a "basic" tool set.

That is /completely/ understandable.
At least your profession is not in cahoots with the insurance industry and academia to push up prices more than any other profession of which I can think, burying customers in far more undecipherable paperwork, for which getting answers is far more difficult.
I won't even elaborate on the countless government "workers" (as well as private industry workers) who post to the net on my tax dollar or on company time, for fun or whatever. One will not see auto technicians doing this. They're too busy actually earning a living.

-->GOOD NEWS! MY PROBLEM WAS SOLVED!<-- I'm happy to announce that late last night when i was driving home, the light turned off. I followed the advice of turning the gas cap a even more - 5 clicks ++.
I believe that it clear that Honda needs to offer the service for free since it should be mandatory to show the ECU code in the dashboard.
This Honda dearlership called me for the regular post-morten "customer satisfaction". I really gave a lot of "1"s. I hope to talk to Honda Corporation.
I believe i need to move to Accura. Same manufacture.... different Customer Support... sad... sad...

The dealership I deal with charges $46.00 plus tax of course, to check the code and reset the light. That's why I purchased the OBD II reader. After six uses it will have more than paid for itself.

I've had the same code come up in the past, once the light is reset (in my case) it never came back on. It could be a very infrequent occurrence. If it comes on again, I would investigate it further at that time.

No, a P1456. No such code as P01456.

Fuel filler cap is loose.
Tighten *at least SIX* clicks. Wait three engine on-off cycles. Light should go off.
If it does not go off, the cap may not fit tightly enough for a proper seal. Replace cap. Occasionally, the threads in the filler necks can be damaged, preventing the cap from being properly tightened.
