It doesn't react to metal or a magnet. Replace vent sensor came loose can not find location for sensor. If you notice them moving all over the map rich and lean chances are you have a faulty evap canister purge valve. July 8, 2017 Followup from the Pelican Staff: Thanks for the additional info and feedback. It is still there I have found the howling tone coming from the check valve. I can't locate it and pictures of a 2008 C4S Turbo depicts its location right of the coolant expansion tank above left of the alternator.
The filler cap on this car mechanically opens the filler vent valve when cap is unscrewed. Does this sensor connect to valve 996 605 203 01? It sounds to me like the howl is being produced during the purge phase. Let the car warm up, then listen to each component closely with a mechanics stethoscope. No idea what this is or where it goes. These type of comments add so much to the Pelican tech community.
June 18, 2015 Followup from the Pelican Staff: That would cause an oxygen sensing fault. If it is stuck open raw fuel could be entering the intake and flooding the car. The vent control valve solenoid controls the flow of outside air in and out of the charcoal canister. It is my understanding that this should not leak when you pull a vacuum on it and the gas filler is not inserted. The car does not start right away but it significantly better than before.
April 8, 2017 Followup from the Pelican Staff: Check if the connector for the vent is shorted. There are no problems with pumping fuel into the tank and the car starts fine except the one time after refueling. I tried filling with a gas can with no luck. Purge solenoids are generally connected close to the intake manifold. Possible something was left unplugged or connected wrong.
Took the car in for service but no fault codes came up. That howl is a result of something not seating in the system, or possibly the canister having some strange resonance producing ability. Drove the car 200 miles and check engine light has recently come on for the first time. They can figure out what part or repair kit you need. I tired to remove the fuel filler tube, but it only comes out about 2-3 inches. Check spark, fuel injector pulse and fuel pressure, volume and quality.

Codes: P0455 P0410 P1411 I have replaced the gas cap and nothing has changed. Tech said couldn't check because Evap Emission Monitor not run by computer, indicated on his tester. August 31, 2015 Followup from the Pelican Staff: I would try the vent valve mentioned in this article. Maybe I need to replace the charcoal cannister as well? May 28, 2014 Followup from the Pelican Staff: P0446 is a flow issue. If the vent line is detached, does it fill normally? Would that be due to a blockage in the line that would close it or something else not working i.
Now I can't fill up gas and the whining noise when you start the car remains but as usual it goes away after several seconds. While refueling, ambient air is drawn into the filler pipe so as not to emit fuel vapors in the air. That would seem to eliminate the basics. Fuel Filler Cap A ratchet tightening device in the threaded fuel filler cap reduces the chances of incorrect installation, when sealing the fuel filler. Car sat for 5 years with blown engine. I have filled up 3 times since and the red light is on and the needle is on empty. Furthermore, first range of rpm, util 2000, are very shaky then the engine becomes regular.
Is it possible to have a picture as to where it should be connected. May 31, 2016 Followup from the Pelican Staff: Thanks for the additional info and feedback. When I called Porsche the answer I got was that the hose that connects to the carbon canister now has the valve built into it so the valve is not purchased separately. Has sensor 996 613 224 01 failed? That magnetic switch pops into that black piece. Using this purge process, the charcoal canister is purged and recovers its absorbing capability.
