Increased emissions: If the purge valve is stuck closed, it can cause the vehicle to emit higher levels of hydrocarbon emissions, which can be harmful to the environment. Reduced fuel efficiency: If the purge valve is stuck open, it can cause the engine to draw in too much air, which can...
What is Purge Valve or Purge Solenoid in a car, problems, symptoms, purge valve testing, replacement
Purge valve problems The most common problem with the purge valve is when it sticks or does not close fully. This may cause the "Check Engine" warning light to come on. In some cars, a stuck-open purge valve can cause difficulty starting right after refueling at a gas station: for the ...
a bad purge valve could be one of them. There are sensors present in the car’s system that track the working of the purge valve, and once the signals from the valve fail to transmit; an indication is a result. Once the sensors detect a loss of signal from the valve, the ...
Stuck, Open or Closed Position A purge valve stuck in the open position may cause excessive fuel vapours to be drawn into the engine, affecting combustion and causing drivability issues. Conversely, a purge valve stuck in the closed position may lead to a buildup of pressure in the EVAP syst...
Often when a charcoal canister starts failing, the charcoal pellets get drawn into the purge line and clog up the purge valve or the purge lines. If a lot of charcoal pellets are found stuck inside the purge valve, the charcoal canister might also need to be replaced. ...
A method for diagnosing a fully opened stuck state of a canister purge valve is provided to diagnose the fully opened stuck state of the canister purge valve accurately on the basis of the change in pressure of a fuel tank when a canister interruption valve is closed. A method for ...

PURPOSE: A control method and a control device for preventing an engine stall when a purge valve is stopped while being opened are provided to detect the purge valve being stopped while being opened by using a control value of an engine control system, thereby preventing the engine stall. ...
PURPOSE: An apparatus and a method for diagnosing failure in a canister purge solenoid valve of an LPG car are provided to accurately diagnose the attachment of a pressure sensor by determining the attachment of the pressure sensor based on the output voltage value of a pressure sensor, the ...
