The procedure is to disconnect the intake manifold purge hose from the EVAP canister purge valve, remove the EVAP canister purge valve and the bracket from the engine, remove the purge valve retaining nut, remove the EVAP canister purge valve from the bracket, and then inspect the EVAP canister purge valve and the EVAP purge system for carbon particle contamination before replacing the EVAP canister purge valve.
