Symptoms of a Faulty or Faulty Evaporative Valve Solenoid
Common signs include a Check Engine light coming on, gas tank pressure, and an emission test failure.
The evaporator solenoid valve is a component of the exhaust gas treatment system that is commonly used in many road vehicles. This is part of a vehicle's evaporative emission system, which is designed to capture and recirculate fuel vapor back into the engine compartment. The job of the EVAP vent solenoid is to allow air into the charcoal canister so the EVAP system can build up pressure and function properly. When the solenoid is open, air is drawn into the EVAP system to relieve any pressure that may result from purging the EVAP system.
When the EVAP ventilation solenoid fails, it can prevent fresh air from entering the EVAP system, which can adversely affect system performance. Usually, a faulty or faulty EVAP ventilation solenoid will cause several symptoms that may alert the driver to a potential problem that needs to be addressed.
1. Check if the engine light is on
One of the first symptoms of an EVAP ventilation solenoid problem is a glowing Check Engine light. If the computer detects a problem with the EVAP ventilation solenoid signal, position, or circuit, it may turn on the check engine light to alert the driver to a potential problem.
2. Pressure in the gas tank
Fuel tank pressure is another sign of a problem with the EVAP ventilation solenoid. If the EVAP vent solenoid is defective, it will not be able to properly vent and depressurize the vehicle's fuel tank. This can cause excess pressure to build up and then be released when the fuel tank is opened.
3. Failed emission test
A failed emissions test is another sign of a possible problem with the EVAP ventilation solenoid. If the EVAP system solenoid valve breaks or develops any vacuum leaks, it could interfere with the operation of the entire system. This can result in a failed emissions test that will need to be resolved before the car can legally drive on the roads.
The EVAP ventilation solenoid is an important component and any problems with it can cause a vehicle's emissions issues. If you suspect that your EVAP ventilation solenoid may have a problem, have a professional technician, such as one from AvtoTachki, have your vehicle inspected. They will be able to diagnose any problems with your vehicle and replace the evaporative valve solenoid if needed.
