Womala Carbon Canister Solenoid Valve LR044012 for Land Rover Freelander 2

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
