1-Way Check Valve

WARNING: This page is about a different car, the 1995 Mazda MPV. However, it is still accessible from the selected car via links, so may be relevant.

Note direction of valve installation. Remove check valve. Blow air into both ends of valve. Air should flow through valve from charcoal canister side but should not flow from airflow meter side (beveled end). Replace valve as necessary.
