Adsorption (Engine Off): Fuel tank vapor flows through the LR044012 pipeline and is adsorbed and stored by the carbon canister.

Desorption (Driving): The ECU powers on the solenoid valve to open it. The engine vacuum draws fuel vapor into the intake manifold, and the vapor finally enters the cylinder for combustion.

Impact of Malfunction

Solenoid valve stuck closed: Excessive exhaust emissions, increased fuel consumption, and carbon canister overload.

Solenoid valve stuck open: Unstable idle speed, weak acceleration, rich air-fuel mixture, and illuminated malfunction indicator lamp (DTC: P0441/P0446).

Dimensions: 110×58×20 cm

Gross Weight: 0.395 kg per piece

Q: How to determine if the carbon canister solenoid valve needs replacement?

A: Signs of a failing solenoid valve include unstable idle speed, weak acceleration, increased fuel consumption, illuminated check engine light (DTC codes P0441/P0446), or excessive fuel vapor emissions.

Q: What should be paid attention to when replacing the solenoid valve?

A: For optimal results, we recommend professional installation. Key considerations include ensuring proper electrical connections, verifying vacuum line routing, checking for diagnostic trouble codes after installation, and confirming all mounting points are secure.
