[bootcamper]

Hi friends.

I posted my problems with this stupid P0446 EVAP Emission Control Malfunction issue here before. Help me TN, I have this evap P0446 problem. and need to beat tickets.

Here is my update.

I am attaching the results.

So it seems, my Charcoal canister is ok.
However, my valve is stuck. How can I change my valve?
Here are the pictures (and test results)

So I took my car to a Toyota for a free diagnostics, and had my codes cleared, and went to a Smog test station and did my test. It passed Smog test.. I will get new tags soon. But I need to fix this issue.

Help me TN.

I recall reading in a Hayne's manual that a valve in the Charcoal canister can be tested. I'm going by memory, but I think it was similar to testing the EGR valve for the ability to hold vacuum. If anyone can verify that this can be done to these valves in the Charcoal canister, please comment!!!! Anyway, a vacuum tester is super cheap at any auto parts store or Harbor Freight Tools. You just basicall hook it up, squeeze the trigger a time or two until the needle gets to the pressure level required for the test. Then you see if the valve stays at that level for a certain amount of time. If the pressure does not hold (indicated by the falling needle), the valve is faulty. Super easy. I'm just wondering if anyone's done this with the valve this guy knows is at fault. Thanks.
