Canister Purge Solenoid: Testing and Inspection
The EVAP Frequency Valve is located in the engine compartment mounted to the right fender behind the air cleaner assembly. The electric solenoid
type valve is controlled by the Motronic Engine Control Module (ECM) using an ON-OFF duty cycle or frequency. The valve routes fuel vapor from
the fuel tank and sends it to either the carbon canister for storage or to the intake manifold for burning.
