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
