check engine light - evap

I have a 2000 accord and keep getting the check engine light, have had it
checked 3 times and each time get the evap code. Does anyone know of any
common problems regarding evap on 200- accord 4cyl? I've had the gas cap
changed, 2 bypass valves leading to the tank, and 1 purge control solenoid -
and still check engine light. Anyone familiar with such a problem?

 

Perhaps the gas cap is not on tight enough? When putting the cap back on,
it should click a few times. Otherwise, a loose gas cap will trigger this
error code.

Also, is the replacement cap OEM or aftermarket? Make sure it is OEM.

 

I had a 2000 Odyssey that had that problem. Turned out to be the gas tank
filler neck.

 

=====================

If somebody is intentionally overfilling it, you can suck a bunch of
liquid fuel into the evap canister, and a CODE will be set. I think it's
in the Owner's Manual.

what are the OBD 2 codes for it? i've had problems with EVAP on my
accord 99 4 cyl lx. But those were easy fixed. Depending on your
codes will determine which parts to replace. Like P1300 or P1301...
These codes are for fuel injectors or oxygen sensor that sometimes
fail. More so for the fuel injectors. Also check out if your EVAP
control is messed up. It's a $60 part here in the US straight from
Honda. Don't know how much it is for them to replace it since I
brought it to a friend I know.

 

The OBDII code was (and still is) P1457 for evap leak. I don't have access
to any list of codes so I have to assume that it really is evap? Is that a
broad category or jsut a few possible parts?

 

==============================

Another hint . . Always quote the CODE, it's on your invoices. If it's
not there, get it from the servicing dealer's computer. You paid for it.
Then run it through google.com, and find out what it (actually) means.

The ODB-II site[1] will translate SAE (generic) codes, and codes for
US manufacturers. It doesn't do Honda, unfortunately; I don't know
offhand if there's a website for Honda's manufacturer codes.

You're getting P1457:

P: powertrain DTC (diagnostic trouble code)
1: manufacturer-specific code (0 would be SAE)
4: auxiliary (ie not directly related to combustion) emissions
57: the specific fault code

P0457 is the SAE code for evaporative leak, so I suspect P1457 is
essentially the same issue.

Pretty much the parts from the gas cap to the tank, I think. So it
could be the cap or the filler tube, or the sensor (I assume there's
a sensor of some sort that detects an evaporative leak - I've never
looked into it).

Other parts of the EVAP system are a canister that traps vapors and a
purge valve and line that allow vapors to enter the engine to be
burned. I think those would have different codes, though.

P1457 Leak Detected In EVAP Control System (Acura, Honda)


from http://autorepair.about.com/cs/troubleshooting/l/bl_obd_14.htm

 

hows your gas cap? stock? aftermarket? old?

if it doesnt seal well, and its not tightened 10 "clicks" it could
trigger an evap code.

 

Hi Mike, it's actually a new gas cap. After I had changed the purge control
solenoid and the 2 bypass valves(at the dealer) put on a new gas cap (yes
it's honda and not aftermarket), cleared the code at the dealer and a day
and a half later the light came back on. Brang new cap I only tight about 5
clicks or so.

 

i don't think it is the gas cap. it could be a sensor module in the
evap canister. since i can't hear what your car sounds like i can't
really tell. I do know that i got that code before and you need to fix
that asap or you might end up getting codes p0300. I believe the part
you need to replace should be on the fuel tank side, driver side
beneath the passenger door. That is the location of the evap sensor
controls. it's a small piece about $60US from a honda dealer. I know
because that's how much I paid. before $20 for labor. Basically it's a
leak in a valve down their that needs to be replaced cause the fuel
isn't sending to the front of the car. i wouldn't be surprised if after
you fix this that you would get other codes. If i ever find the part
that you need i'll post it,

 

P0442 and P0456 are small evap leaks. P0457 is a loose gas cap. Those are
mandated by the EPA, and are common to all makes and models.

Your code is a non-mandated "enhanced" code. Honda decided to put it in
there themselves.
P1456 is an evap leak having to do with the /fuel tank system/.
P1457 is an evap leak having to do with the /charcoal canister system/.

You may have a damaged line or something. Has the car ever been in a
collision?

 

It has nothing to do with your gas cap. That would be code P0457.

See my other message.

 

Ok, I'll go with the suggestion of:

to your question about the damage - no it hasn't been in an accident before
that I know of. I got the car when it had only 23,000KM on it and now a year
and half later I'm at 65,000km when this all started.

 

help on oxygen content , what does it mean? can it be fix by cleaning it or
spraying with brake cleaner?

 

Make?
Model?
Year?
Error code number encountered?

We're not mind-readers here, you know.

 

The OP said it was a 2000 Accord.

 

========================

WAY too many details . . information overload. All you've told us is
your name.

He did? My news provided must have dropped that post, becuase all I see is
what I replied to.

In any case, he has not given the exact error code.
