Hello again old friends.

I am not referring to the Purge Valve in the engine area, but rather the Shutoff Valve which sits next to the Canister in right rear of vehicle. There is not much posted on this. It costs $130. How do I test it? (I am replacing the J-hose and L-hose (both cracked/dry-rotted) which attach to this valve).

As always, THANK YOU for your assistance.

I pulled the valve out and applied battery voltage to it directly. I could hear the solenoid click, and sure enough, the passage was sealed off tightly (it was open with no voltage). So at least I know the unit itself is good.

As I said above, I am replacing the hoses , which are cracked right through. I will also replace the inline Vapor Canister Filter (9186744) at only $4.59.

IS THERE ANYTHING INSIDE THE LARGE RECTANGULAR CHARCOAL CANISTER WHICH REQUIRES REGULAR MAINTENANCE? I probably flooded it with liquid gas several times, before I learned not to overfill the gas tank. Would that have damaged anything inside the canister?

It is filled with charcoal and is NOT servicable. As the vapors get drawn to the intake, the charcoal will hold less and less gasoline. Having liquid gasoline in the cannister does not hurt it, it just impares the normal evaporation process.

Replacing the hoses will turn off the error code.

Did you do your Random Act of Kindness today?

Sure enough, I replaced the two hoses and codes were gone ...

However, I had disconnected the battery before removing the solenoid valve, and so I ended up with six monitors that needed to re-set before getting my state inspection. I used this driving cycle method: http://www.brickboard.com/AWD/volvo-1410555.html

After two of these driving cycles I still had all six monitors flashing - Bummer. I drove the car a few more times, not even doing the cycle, but figured I'd check the OBD for the heck of it ... All monitors re-set!
