If and when mine fails, I plan on saving a couple hundred bucks on labour by doing this myself, all thanks to you! I'm attempting to try and fix the valve spring and plunger first before buying a new one. This time it failed in the closed position which prevents air from escaping when you fill the tank. Typically a bad vent valve does not hold vacuum when activated, or doesn't activate at all. A plunger will then move to seal the canister vent. I removed the part and it was indeed broken. On a side note, How would we go about setting this up, where would you take payment through.
I have heard this process may be very similar if not identical for other years of Nissan Sentra's as well. If your not a real slender person you'll have to jack it up. You could also get the part form a junk yard. What I was really wondering is if something else that's broken on the car might potentialy cause this. When the vent is closed, under normal purge conditions, the evaporative emission control system is depressurized and allows Control System Small Leak diagnosis.
Common problem on nissans, umm, I may have some at work now that id sell for like 30 bucks + shipping. I am assuming something gets hot since there is a heat shield there with vents am I right? Use the information in this video at your own risk. Release the part to some aftermarket producers already you greedy bastards! The swirl control valve uses a step motor which has four winding phases. So I just keep erasing the code as often as I feel like using the pedal trick. All this to keep a little gas vapor from escaping top the atmosphere. Many tries and repeated cleaning, got the same result. Actually, P0455 is a non specific pressure drop.
This solenoid valve responds to signals from the Engine Control Module. I'm having the same problem - haven't been to the dealership but I was thinking about just getting the part and doing it myself. The air still comes out of the floor vents. Well while I appreciate your offer and will more than likely take you up on it. Always adhere and follow safe practices when working on vehicles.
Not sure if this is one of those deals where as long as it's apart, they just like to change both since it's more labor than parts intensive?? Sinse you went so far as to pull the valve ,make two jumper wires and connect to your car battery and carefully apply voltage to see if the valve works. Just figured i'd let you know. Is there anything else I should check before I throw it on, and a few months down the road its ruined again because of another problem I didn't know about. Sadly there is no warranty on this. Do not use aftermarket gas caps, as the seal may not be as tight.
The failed part was the newer and supposedly better valve. If you don't click it several times and get a good seal it will also trigger the same code. For example, a failed vent valve often caused a Check Engine light with the code P0455 Evaporative Emission Control System Leak Detected in some Nissan and Infiniti vehicles. By this time, I didn't have much daylight left so had to put everything back together. The problem is that that valve can get dirt in it, and seize open.
On a side note, How would we go about setting this up, where would you take payment through. I'm ok with this, but before I go buy the part and replace it. Now the manual tells us to apply the vacuum and see if the vent valve holds it. For a better demonstration, we removed the vent valve and tested it separately. So, as soon as that P0455 comes back, I'm going to the dealer to have them do the inspection.
I'm thinking about just getting a price to the dealer replace the valve only. It's on the breather separator. Also, water can get into the canister - if that happens, you need a new canister expensive. When I checked our car, the wires were fully disconnected so I am having the wiring Harness replaced at a local repair shop tomorrow. Thank you very much in advance! Did the valve pop out easily for you? One side of the vent valve is connected to the charcoal canister. Let me know, and thank you very much for the offer.
