I pulled one out just to take some pics, as I forgot last time:
First pic shows the location of the port side OCV, the starboard one is exactly opposite.
To get it out, first pull off the blue plug, then slide off the hose marked, this doesn't have a clamp on so just pulls off.
Then remove the bolt with a 10mm socket.
The OCV then just slides out, you may need to prise it out as it's tight on the O ring.
This is what it looks like when it's out:
It doesn't come apart, the solenoid is clamped onto the valve. All I did was to operate the spool by hand to make sure it slides easily, clean up with WD40 if it's sticky.
Since I had both mine out, I have never had the CEL return, and no more stalling at idle.
I have the part numbers if you want to order new ones, I think they are around $160 each. What makes me laugh though, is that the dealer quoted me 2 hours labour to replace them
