If there is a leak, such as a cracked vent hose, loose or leaky gas cap, poorly installed or defective O-rings on the fuel level senders on the fuel tank, etc. With one hose off, it is a little easier to reach the second clamp. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. The Evaporative Emission Control Monitoring System monitors fuel vapor generation, evacuation, and a leakage check step.
If you have leaks in the lines from the carbon cannister to the intake, intake leaks, a defective purge valve, etc you will often get purge flow faults. In most cars, the purge valve is normally closed, meaning it should be closed with no voltage and open when the voltage is applied. I wouldn't assume that your mechanic doesn't know what he is doing. Usually, a bad purge solenoid will display any of the following 5 symptoms that can alert the driver of a potential problem in need of servicing.

It is behind the air filter. On the cannister to intake side, leaks are detected by deviations in the idle control system.
The purge valve precisely controls the amount of fuel vapor that is purged from the charcoal canister. All of this stuff is explained quite well in there. Also, I have to drive across the country about 2,000 miles in about a month, so I'm guessing even if it's not an urgent repair I should get it resolved before then, yes? My canister purge solenoid was not working properly. Its quite easy for a wire to become worn and frayed, or a rubber hose to become brittle and cracked. I have been calling it a valve and a solenoid. Sep 17, 2010 if you mean the evaporator hose for the air conditioner.
Hello, The evap solenoid is located and the bend of the intake manifold. First, I located the canister purge solenoid. Didn't have a problem since 3weeks ago. During refueling, as fuel enters the fuel tank, a vacuum is created in filler pipe, drawing air into the filler pipe and tank. You can always remove it and shake it. Check Engine Light Comes On A defective canister purge solenoid may also set off the Check Engine Light.
The fuel tank is not vented, but rather the vapors are piped to the carbon cannister usually located behind the pass. That time, it would start after I waited for a few minutes and then tried again. The vapor canister can be removed and checked to see if it is full of raw gas not supposed to be , but checking it for leaks is a bit involved, and probably requires equipmet not normally owned by a home mechanic.

Any other time and they will simply test good because the problem isn't present at the moment.
