Can you drive with a bad vent solenoid?
While you can still drive your car with a bad purge valve, you will only expose it to further damage not only to the EVAP system, but as well as to the other parts in your vehicle. The more you drive the vehicle with a bad purge valve, the more you will harm other parts. It is necessary to fix the problem eventually.
Where is the vent solenoid located?
In most cars, the EVAP vent valve is located underneath the vehicle, close to or at the charcoal canister near the fuel tank, see the photo. For that reason, it often fails due to corrosion. The most common problem with the vent valve is when it sticks open or fails.
What is the purpose of the vent solenoid?
A vent valve solenoid is an electromagnetic actuator used to remotely or automatically open and close vent valves used as pressure relief devices. The solenoid is a widely used actuator type consisting of a wire wound coil and a ferrous metal plunger.
What is an EVAP system Purge and vent solenoid?
It is the job of the EVAP vent solenoid to allow air into the charcoal canister so that the EVAP system can pressurize and function properly. When the solenoid is opened, air is allowed into the EVAP system to relieve any pressure that may be present as a result of purging the EVAP system.
Where is the EVAP canister vent solenoid?
EVAP canister is right behind the gas tank on the driver’s side. The EVAP canister vent control valve is located on the EVAP canister and is used to seal the canister vent. This solenoid (the EVAP canister vent control valve) responds to signals from the ECM.
What is the function of a canister vent solenoid?
The vapor canister vent solenoid is a part of your car’s evaporative emissions control (EVAP) system, which plays the essential role of purging the vapor from the fuel tank and venting it out into the engine for combustion.
