Evaporative Emission Valve

Evaporative Emission Valve: This ECM controlled solenoid valve (located on the front of the engine) regulates the purge flow from the Active Carbon Canister through the air inlet pipe into the intake manifold.




The ECM Relay (in the IVM) provides operating voltage, and the ECM controls the valve by regulating the ground circuit. The valve is powered open and closed by an internal spring.

If the Evaporative Emission Valve circuit is defective, a fault code will be set. If the valve is "mechanically" defective, a driveability complaint could be encountered and a mixture related fault code will be set.
