Default Help with 1998 Camry 'Check Engine' code - P0441 - EVAP Emission Control System - Purge Flow Fault???

Hello,

I had AutoZone retrieve a P0441 engine code the other day. They said
it was a bad gas cap but when I Googled the code, it looked like some
other 'doo-hickey' was involved and it said to "Remove and replace
Vacuum Hoses between EVAP VSV and Charcoal Canister or if there is a
metal vapor pipe between EVAP VSV and Charcoal Canister, clean inside
of vaporpipe, and lastly, replace EVAP VSV and Charcoal Canister
assembly with new parts

What I would like to know, are these fixes tough to accomplish? Where
can the parts be found? If anyone has ever fixed this problem, can you
give me some pointers?

Thanks in advance,

Kaz

Unless your state INSISTS that you not have that code, that work is NOT
necessary. I got that code, here in Alberta, last year. Turned out to be
caused by overfilling the gas tank. After the first click of the gas pump,
STOP, put no more gas in. Code has never reoccurred since it was cleared
out.

I wish mine were that easy. I've cleared the code twice and it just
comes back on. I do know about the over-filling problem so that
probably isn't the cause... although... the engine light did come on
right after my last fill-up.

Thanx for the response!

This is my experience with a 2001 camry. There are three vacuum
switching valves (VSVs) for the evaporative emission control system.
One is on the air filter housing. It is easy to check. Two are on the
charcoal canister. One of them can be replaced. The other requires
replacing the canister.

To check the removable ones, remove them from the vehicle -- they have
two or three hose fittings and an electrical connection. Run 12 volts
across the electrical terminals. You should hear a click. If you
don't hear the click, the valve is bad.

They cost about $57 bucks each. Chances are good one of them is bad.

The Haynes manual has a procedure for checking the vacuum and the
valves.

Also check this site for diagrams and diagnostic procedures:

As for the dealer, they wanted to replace the canister and the vacuum
control system and clean the intake $1200. I fixed it for $57.

Good luck,

MD



The removable one on the charcoal canister is a bit of a bear to
remove because the screw holding it on the bracket is so small, but it
can be done. Having the car on ramps helps a lot.

You need to check the VSV that's on the air filter housing. Disconnect
the the rubber hose on the side of the carbon canister (towards the
rear of the car). You run the engine for a while and you should hear
loud sucking sounds from the VSV as the thing cycles. Anything less
than that the VSV is sticking.

If this VSV isn't working, and it's the type that has metal tabs
holding the port caps, then you can carefully pry away the tabs and
clean/lube it. Can save you $60 before you head to the dealer, and
should last a while after cleaning.

In my experience, as soon as I stopped overfilling my gas tank, I ceased
getting the 441 code. (after clearing the code out).

Never mind - I found the problem. There is a (vacuum?) hose leading
into the housing of the air intake cleaner housing. The nipple that is
molded to the housing is completely cracked and the hose is off.

I just glued it back on with a big glob of epoxy, reset the check
engine light and will watch for a couple of days.

I'll report back the results.

A BIG thanx to all who responded!!!

That was the fix - lots of epoxy and duct tape. Four days and no check
engine!!!

Thanx,
