I've been getting a P0442 periodically from my 97 850 wagon (base, no turbo). I've replaced the gas cap, the electrical part of the ignition switch, and all the deteriorated rubber vacuum-hose couplings I can find under the hood, but I'm still getting the code. I want to inspect the hose couplings at the evap canister, but there doesn't appear to be any way of getting to them other than removing the canister from under the car. Is there any other access to these?

Also, I've got VIDA running on my PC, and even though I've given it the VIN, it shows me the wrong evap canister in the parts diagrams. It shows the cylindrical canister, but my 850 has the rectangular canister. Does anybody know where I can view accurate diagrams showing the evap components in this car?

 

Hi and welcome to the forum.

You likely have a torn vacuum hose near your fuel filter, I believe they call it a J hose.

 

Two useful URLs - volvotips.com and volvopartswarehouse.com You should be able to get some useful info, diagrams from both.

 

Thanks everybody. The hoses at the rollover valve are deteriorated. I ordered them today and should get them later in the week. As long as that was the only leak in the system, my problem should be solved.
