So what do I do next? If your are for a different car, select that vehicle series before searching for the diagnostic codes because not all used by one manufacture are used by the other makes. I spliced in a new wire and drove around for the past two days and the error hasn't came back. When the engine is running, the purge control solenoid opens the purge control valve, allowing engine vacuum to draw fuel vapors back into the engine where they can be burned as fuel. To detect vacuum leaks, they place the nozzle of the smoke machine close to the vacuum supply hose for the purge solenoid and fill the system with smoke. Would have to perform a voltage drop test on the wires to verify harness ok. YourMechanic offers certified mobile mechanics who will come to your home or office to diagnose and repair your vehicle. However, other evaporative emission control system codes are likely to be present.
With the purge control solenoid open, check for suction at both sides of the canister. The function of this valve is to temporarily seal the canister vent. So you should chech it on our car models. A P0447 code will be enough to cause a vehicle to fail an emissions inspection, however. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing.
Attempt to draw a vacuum on the valve. Located just behind the drivers rear tire behind the inner liner. Be sure to check tubes, hoses, gas cap gasket, fuel fill tube, and charcoal canister for damage or cracks. We are not responsible for any actions you take on your vehicle. You have to remove the valve ad supply battery power to it and see if it operates. This is not to be confused with the purge valve, which purges the charcoal canister when the engine is started. Use a 12 V jumper to open the valve.
When it starts to make a clicking noise, the purge valve should be open. Symptoms Normally, no symptoms other than a stored code and a service engine soon lamp will be exhibited. How serious is the P0447 code? If the canister is working normally, then the check the fuel vapor hoses for crushed areas or kinks. So I would stick with the vent valve circuit. The vent control valve is normally open; it controls the air supply into the canister. Enter the 5 character trouble codes in the search box and submit the search. Although this video has been prepared with the intent to provide reliable information, no warranty express or implied is made as to its accuracy or completeness.
The other is a wiring issue. Thanks, Paul Hey Paul, Did you ever figure this out? I think It may be wiring related for this sensor too since I replaced it. Checked the wiring at least everything that was accesible for any issues, and didn't see anything bare, fraying, or otherwise out of the ordinary. Usually, this requires one or three clicks for proper sealing. Neither is any liability assumed for loss or damage resulting from reliance on this material. Also shake it and see if the valve inside moves. Finished up by removing the nut on the ground stud in the wheel well, cleaning stuff up a bit with a wire brush, reassembly, and a hard reset of the battery.
How do you troubleshoot code P0447? Thanks, Paul Just thought I'd post a quick update, since I'm still dealing with this. Remove it and shake it. They connect the code reader to the diagnostic connector, record stored codes as well as the freeze frame data. I finally figured out how to solve this issue. If that is the case, then check the electrical connectors and look for signs of corrosion and damage. What causes the P0447 code? Common Misdiagnosis Evaporative emission control system components are often replaced in error when a vacuum leak is present or the fuel cap is not properly tightened.
So with any of these the first thing to check is the wiring. Replace the canister if needed. Not every auto repair shop has this equipment, you might need to visit a dealer or a larger well-equipped shop for repairs. There are many great features available to you once you register at RennTech. . When refueling is completed, the gas cap should be reinstalled and torqued properly.
When the pump stops, the valve should close. Check wire harnesses for obvious damage, perhaps due to chafing, misrouting or impact. It looks like a small cylindrical solenoid with the two-wire connector and vacuum lines attached to it. Most valve solenoid should measure between 30 Ω and 40 Ω, though some newer electronically-controlled valves may range between 2 Ω and 6 Ω. You have to stop at the first click.
The bulletin recommends checking the vent valve assembly and if needed, replacing with an updated part. If someone here can access the vapor recovery system diagram, that would be a big help. Stored codes presented without malfunction indicator lamp illumination may be read as pending codes. It should hold vacuum for at least a minute without dropping. The description indicates that the vent valve is on the canister and purge valve on the engine. The red wire is the ground and it was totally disconnected from the harness. The fuel vapor and vacuum lines are fairly long and are vulnerable to damage from road debris, age and the elements.
Relocating the vent hose to a cleaner or more protected location generally fixes the problem, though you may be able to get away with cleaning it yourself. Some models require multiple failure cycles for service engine soon lamp illumination but a code is normally stored on the first failure. 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. The code is for the vent valve circuit. When the car came back from the valet, the check engine light was lit up solid light. If you have any doubt as to repairs on your vehicle, please contact your technician. They will look for signs of rubbed-through wires or a chafed wiring harness.
