EVAP charcoal carbon canister

Postby KEWROCK » Thu Oct 21, 2010 9:04 pm

'99 v70r awd 125k

Hey guys.

I'm still trying to get the CEL light off. It's been on for about two years. I've made numerous attempts to fix it, but usually give up.

I can't seem to find the EVAP canister and problematic J-hose I keep reading about in other threads. I've got codes po446 (EVAP vent control circuit malfunction) and po453 (EVAP pressure sensor high output). From what I gather the 850 and V70 2wd canister is behind the driver side bumper. The V70 AWD is in the rear passenger side behind the axle. I've posted a couple pictures. The hoses seem OK if I'm looking at the correct item. I'm guessing the fuel filter the large drum(if it is, it's the largest fuel filter I've ever seen). And the EVAP is the unit to the left with the two hoses attached.

I also read that the electronic sensor attached to the radiator bracket on on the top driver side goes bad. Can anyone elaborate on that? I've attached a picture of that too. Please correct me if i'm wrong I'm not sure if I'm looking at the right part

That is the fuel filter, but on my 98 V70 AWD the evap canister is perched up behind the bumper, in front of the wheel well, on the driver's side.

Yep, that's it. They move the darn thing around at random between years and makes/models. Some 98's have it up front; some don't - I believe most of the newer models have it in the rear.

I would say that your valve on the radiator is the one to blame in this case. It doesn't sound like it's opening when it's supposed to.

What's that valve called? Is that the EVAP pressure sensor mentioned in error #453?

The hoses all seem good. A little mushy, but every piece of rubber on the car is soft and mushy. No tears or splits though. Anything else you can think of while I'm ordering parts? I guess I'll order from FCP Groten? Seems MY Volvo Parts Online no longer advertises on this site.

HUGE THANKS !!!!

That's the "purge valve". As far as I know, at least on a '98 model, there is no other "pressure" sensor in the system. That valve must control that too. It's a pretty common failure point as well - mine has been replaced at some point too.

Oh, and MyVolvoPartsOnline will be back as our sponsor at the end of this month:

I made a howto on testing and repairing the purge valve. I would at least test it to make sure it is your problem.

Thanks guys for all the advice. I'm going the way of a new one. It's relatively cheap, $35 at Grotin Parts. Besides, I need a handfull of other things too.

Hey Cheat, What makes them go bad. Do you know?
