Hi,

I have a 2000 (Canada) V70 and this light comes on and when I check it
the error massage is P0442. I can clear it and it usually comes back on
after about 1/2 an hour.

It says that it is a EVAP Emission Controls small leak.

What I've read says that the valve responsible for dumping un- burnt
gases back into the mix could be at fault by not closing back up ( I
assume after it is warmed up?) or there may be a line leak between the
gas tank and the vapor recovery (is this the charcoal container?) or it
might be a gas cap leak, or in some cases the filler pipe to Gas Tank
fitting may be leaking.

I was told the easiest way to find a leak is use a smoke system and
inject the smoke, then view the system for smoke leaking out?

Does anyone know of a cheap smoke system?

Cheers,

Tom eh in Canada

Update: Last Night Aug 30, I cleaned around the edge of the gas cap
where it meets the edge of the neck on the tank and put it back on as
tight as I could manage (pressing in as hard as I could to stop it from
slipping). I reset the error drove without another error and then filled
up with gas and did the same. 24 hours later, there still isn't an error.

I'll keep my fingers crossed.

Tom eh
