        Slide the clip and disconnect the vent line hose from the canister (charcoal canister assembly).

        Note


        • Remove any dirt or foreign matter on the vent line hose before performing this work.

        • Only pull off the vent line hose by hand.

        • Do not forcibly bend, twist or turn the vent line hose.

      2. Close the vent line hose using a hose plug or similar part.

      3. Connect a test hose to the canister (charcoal canister assembly).

      4. Blow 5 kPa (0.1 kgf/cm2, 0.7 psi) of air into the test hose and check that air passes through the canister (charcoal canister assembly).

        If the result is not as specified, replace the canister (charcoal canister assembly).

    3. Check canister (charcoal canister assembly) operation under vacuum.

        Slide the clip and disconnect the vent line hose from the canister (charcoal canister assembly).

        Note


        • Remove any dirt or foreign matter on the vent line hose before performing this work.

        • Only pull off the vent line hose by hand.

        • Do not forcibly bend, twist or turn the vent line hose.

      2. Close the vent line hose using a hose plug or similar part.

      3. Connect a test hose to the canister (charcoal canister assembly).

      4. Connect a vacuum pump to the test hose.

      5. Using the vacuum pump, apply vacuum and check that the vacuum pump indicator does not move from its initial position.

        Tech Tips

        The vacuum pump indicator may move when applying vacuum. If the vacuum pump indicator quickly returns to its initial position, the canister (charcoal canister assembly) is operating normally.

        If the result is not as specified, replace the canister (charcoal canister assembly).

    4. Check for clogs in the air filter (when not using the GTS).

      2. Close the vent line hose using a hose plug or similar part.

      3. Connect a test hose to the canister (charcoal canister assembly).

      4. Connect a vacuum pump to the test hose.

      5. Start the engine.

      6. Warm up the engine.

      7. Idle the engine for 15 minutes and check that the vacuum pump indicator does not move from its initial position.

        Tech Tips

        The vacuum pump indicator may move when the purge valve (purge VSV) opens to vacuum. If the vacuum pump indicator quickly returns to its initial position, the canister (charcoal canister assembly) is operating normally.

        If the result is not as specified, replace the canister (charcoal canister assembly).

    5. Check for clogs in the air filter (when using the GTS).

      Tech Tips

      When performing Active Test of the purge valve (purge VSV) using the GTS, it is not necessary to warm up and idle the engine for 15 minutes.
