Default 2005 WRX Evap canister purge valve location?

I have a code for a leak in my evap system. I have checked all around and can't spot any leaks. I bought a purge valve for my 2005 WRX. This one
http://www.am-autoparts.com/Subaru/I...tm_content=EMX

Now that I have the part, and I have dropped the canister down. I dont see any part back here that even resembles this. The only valve that is back here is a small valve with 3 small hoses going to and from it. The hose that goes to the canister that is the same diameter as this valve I purchased goes into my frame and opens there, it isn't connected to anything.


A little help?

I can snap pix if necessary.

Thanks!
-Dave

Typically the PCSV is located on/under the the intake manifold. One end of the solenoid goes to the intake and the other to the fuel pipe vent line. It's simply an on/off valve, at idle the valve is closed, under load it opens and vents back to the carbon canister.

What does PCSV stand for?

The closest write up I have found is this one.

http://cars.natemichals.com/subaru-2...ment-write-up/

This is the same part I have, the problem is, on my car that tube just vents right into the frame.

I also found a tube that goes from #2 to #3, it was unplugged. I dont know how! But it was. I suspect this is the culprit of my check engine light. I have put 30 miles on the car since I plugged it back in, but my CEL hasn't gone off. I think I am going to re set it and see if it comes back on instead of seeing if it goes away.

What do you think?

Went to the parts store today and deleted the code with a scanner and it came back within 2 seconds of me turning the motor on literally. Ideas?

Thanks, help is appreciated!

Try checking the lines running to the evap purge and make sure they are all connected and routed correctly.

All the lines are routed correctly, and are free of dry rotting or loose fitting connections that would cause a leak.


Should I replace the valve near the intake manifold?

I want to send this purge valve back. I dont think it fits anywhere on my car.

I'm pretty sure a loose gas cap can cause this code. If I'm wrong sorry, but it's worth a shot and free.

I've had the code for a couple months now and have tried the gas cap a few times.

Twice so far, it stayed away for 3 or 4 days the first time, the second time it came back within seconds of clearing the CEL and starting the car again.

Thanks for the try : (

Anything else?

They say sometimes it tank sediment clogging the valve other than that you might have to the smoke leak to rule a seal or picked hose

Is my evap and charcoal canister supposed to look like this?
This is from a 2004.
[IMG]file:///Users/davidbrandt/Desktop/part%20list.jpg[/IMG]

My canister is very similar to this, but hose #33 just curves up, back, and into the frame of the car. It doesn't connect to anything. I dont have #8, or #23 or any of those pieces. I am about to make a video to show everyone what my car looks like. I want to fix this so0o0o bad!

Thank you everyone for your help so far

Purge valve is under the front of the intake manifold. The piece above the evap canister is the pressure control valve. When that one fails, it becomes very hard to fill your gas tank. Usually when there is a code related to the purge valve, you will find that the vacuum hose pushing onto the front has popped off. At least that was the problem on two subarus I have fixed because of this code, when it was a small evap leak code that was thrown. Typically when a bad gas cap is the cause the code will be for a gross (big) evap leak. Good luck and let us know what you find...

Also, the system performs a self test for evap leaks when you cruise at steady engine load on the freeway for 30 seconds or more. After you make a change and reset the computer, do this to test to see if you are clear.

That valve on the front under the intake manifold did have a hose that had popped off of it! There was a small blue connector and one of the rubber hoses was disconnected. I thought for sure that I had found my problem, but after re- setting the ECU and driving for several days my CEL was still there.


What would cause that small tube to pop off? Should I replace the valve by the intake manifold?

Zip tie the hose on, or replace with a new not hardened 5/32 vacuum hose that won't come off easily. It may be that the hose is just not fitting properly causing the leak. My best guess as to what causes it to pop off is just a poorly fitted hose, and boost. Both cars I have fixed this on also had turbo inlet pipes (one of those cars mine) that pushed on the valve a bit, and added to the stress on the hose.

I'll go check the hose tomorrow.

Thank you!

Tube isn't still popping off and lines fit pretty snug. I replaced the gas cap for ****s and giggles and the code refuses to go away

Anything else?

All the usual suspects have checked out, take it to a repair shop with someone who understands emission system diagnostics and get it smoked. It'll turn up then. Good luck!
