Purge Solenoid

The purge solenoid allows hydrocarbon vapor flow from the charcoal canister to the throttle body. The purge solenoid is timed to the throttle position but is disabled at startup, low engine temperature, low engine speed, or low vehicle speed. The power for the solenoid comes from the system relay. The EVMS provides the path to ground to trigger the purge solenoid.


Before removing the purge solenoid, perform diagnostics listed in the VRSCA Electrical Diagnostic Manual (Part No. 99499-02).
