CANISTER(w/ Canister Pump Module) INSPECTION

PROCEDURE


  1. INSPECT CANISTER (CHARCOAL CANISTER ASSEMBLY)


    1. Visually check the canister (charcoal canister assembly).


      1. A01QB70

        Visually check the canister (charcoal canister assembly) for cracks or damage.

        If cracks or damage are found, replace the canister (charcoal canister assembly).

    2. Check canister (charcoal canister assembly) operation.


      1. A01Q9P9C03
        *a Vent Line Port
        *b Air Line Port
        *c Purge Line Port
        *d Air

        With the purge line port closed, blow 0.5 kPa (0.005 kgf/cm2, 0.1 psi) of air into the vent line port, and check that air flows from the air line port.

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

      2. A01QBF7C03
        *a Vent Line Port
        *b Air Line Port
        *c Purge Line Port
        *d Air

        With the vent line port closed, blow 0.5 kPa (0.005 kgf/cm2, 0.1 psi) of air into the air line port, and check that air flows from the purge line port.

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

    3. Check for air leaks.


      1. A01QA3SC02
        *a Pressure Gauge
        *b Vent Line Port
        *c Air Line Port
        *d Purge Line Port
        *e Canister Pump Module Connector

        Connect a pressure gauge to the vent line port.

      2. With the purge line port, air line port and canister pump module connector closed, apply 20 kPa (150 mmHg, 5.91 in. Hg) of pressurized air into the vent line port, then confirm that pressure is maintained for 1 minute.

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

    4. Check the canister pump module.


      1. A01Q9M0

        Connect a positive (+) battery lead to terminal 5 and a negative (-) battery lead to terminal 1.

      2. Check that a clicking sound is heard from the canister pump module.
