A charcoal storage reservoir, electrical solenoids and engine vacuum come into play to accomplish this. When the engine is running and other conditions allow, the fuel vapors are purged from the charcoal canister into the engine air intake to be burned see the diagram. I think It may be wiring related for this sensor too since I replaced it. I read the codes when I got home and had P0447, P2400 and P1482 were present. They will check both wires to see if they are open to each other, to ground or power. They check the fuse, as there may be a fuse that powers the vent solenoid.

The description of the fault varies between different car manufacturers, but one thing is common, the code P0446 doesn't directly point to a defective part; some testing might be required to pinpoint the faulty component. The fuel vapors from the fuel tank get trapped in the charcoal canister; the charcoal canister is filled with small pellets of activated charcoal that absorb and store vapors. So what do I do next? They will conduct repair as needed.
Enter the 5 character trouble codes in the search box and submit the search. All donations go to the costs operating and maintaining this site. The valve itself is probably located at the top of the fuel pump assembly, but it might be separate, located by the top of the fuel pump assembly. I spliced in a new wire and drove around for the past two days and the error hasn't came back.

The description indicates that the vent valve is on the canister and purge valve on the engine. If the lines are normal, test the operation of the purge control solenoid. Problems leading to a P0447 code can mean failing an emissions test and adding hydrocarbon fumes to the atmosphere. On most vehicles the charcoal canister is located near the fuel tank, under the vehicle. So you should chech it on our car models.
I really need someone to point me in the right direction? In addition, all the involved vacuum hoses need to be cleaned or replaced. However, the fault code is enough to cause the vehicle to fail emission inspection. Would have to perform a voltage drop test on the wires to verify harness ok. The currently selected is for the Nissan makes. Remove the canister and shake it as you listen for broken or loose particles or other rattles.
During refueling, the engine should not be running. I have replaced the Vapor Canister Purge Valve Located on the Canister under the rear of the vehicle , but problem still exists. The list of automotive Makes at the right edge of the screen. The vent control valve is usually installed at the back of a car or truck; near or at the charcoal canister.
