The first step in servicing the evaporative emission canister purge valve requires disconnecting the battery ground cable because this minimizes electrical spark formation that could ignite fuel vapors. Service begins by disconnecting the power connector from the EVAP canister purge valve before conducting quick connect procedures between the
Intake Manifold and EVAP canister purge valve vapor tube and finally the EVAP canister to EVAP canister purge valve vapor tube. Remove the bracket retaining the EVAP canister purge valve by pulling its release tab. The installation of the new valve must follow the opposite order of removal procedures. The system requires a leakage examination following installation and demands completion of the evaporative emissions repair verification drive cycle to verify operational functionality.
