how do i clean it

On the bottom of the valve you will see two holes, one that is plugged with what appears to be a screw and one that is open.
The screw like object is the valve. You should be able to press it in easily and when you let it go, it should close itself again (it's spring loaded).
The one I was working with was sticking in the closed position.



To clean the valve, simply spray carborator cleaner on and in the valve and wipe the dirt off with a cloth. Be very careful not to get it into
the canister, as the carb cleaner is a very powerful deturgent that will eat away the insulation on the windings in the sensor.

The following picture shows what you should NOT do.


The picture below on the other hand shows the right way.


Once you're all done cleaning the valve, you can reuse the gasket and put it all back together.
