My charcoal canister vent solenoid on the '98 Legacy isn't holding vacuum when energized. Hope this will finally solve my evap emissions codes. (Replaced the rusty filler neck, replaced rat chewed through wiring to the vent solenoid, replaced a rat chewed through evap hose....)

 

Anyone know the P/N for this? I can't find it on the online subaru parts places. They list some solenoids, but there are three different ones (purge, pressure control, vent) and I want to get the right one the first time!

 

I did do a search.

 

TIA,

If it is the purge control solenoid under the intake manifold it's 16102AA080

This is the valve under the #3 intake runner on the engine.

There are several other valves back by the fuel tank. These are all difficult to identify due to the way they are labeled.

Tell me about it! I think I'm going to call one of the online parts suppliers and let them sort it out. It's definitely the vent solenoid, not the purge or pressure control ones....

I'm not sure that you are correct on that part number. I searched the part number you listed and it came up as the Duty Solenoid Valve for a newer turbo Impreza. I had to replace the purge solenoid valve on my 98 ej25 legacy and the part number I used was 14774AA271.

 

The part number for the "solenoid for canister purge valve" is 14774AA341

 

You may want to double check for your application but I believe the 2.2l uses the same part number.

 

Here's the subarupartsforyou.com look up for both of those parts and explicitly lists the placement for each valve. not sure which one you're hunting down.

The part number you listed opposedforces shows as the Pressure sources switching solenoid for the MAP sensor.

#5 here.

But. that's not to say they didn't use the same solenoid twice or even three times on the same car.

I've tried to look some of these up before, and the names Subaru has for these various solenoids in their catalogs are very confusing. The only way to really know for sure which one you need is to look at it, because even the parts reps often can't find the right ones.

 

SP4Y is useful for pictures if nothing else.

Its often written/stamped onto the part itself.

I replaced it and it fixed the problem! Passed OBDII emissions inspection just the other day.

 

I used P/N 42084FA120. It's got large bore (> 1/2") fittings on each end. The '98 Legacy and '98 Outback use completely different vent solenoids. The outback uses a smaller bore vent solenoid.

 

BTW, here's the diagnostic procedure I used. Pulled purge line off of charcoal canister, applied vacuum to the purge fitting on the canister (using a mityvac) while energizing vent solenoid valve with 12V. It should hold vacuum. If not, plug the end of the vent solenoid hose leading to the canister. If it doesn't hold vacuum, you've got a leak elsewhere (filler neck, gas cap etc.) If it does hold vacuum, reconnect the canister>vent solenoid hose and pull the hose off the other end of the vent solenoid. Plug the end of the solenoid and see if the system will hold vacuum now. If so, the solenoid is faulty. There are more straightforward ways to check it (you could just apply vacuum directly to the canister side of the vent solenoid while applying 12V to it) but I didn't have the fittings to adapt my 1/4" mityvac hose to the large bore hose for the valve.
