Evaporative Emission Control Canister: Testing and Inspection

CHARCOAL CANISTER INSPECTION [MZR 1.5]

Leakage Inspection

1. Remove the charcoal canister. (See Service and Repair.)

2. Perform the following procedure:

- Assemble the hose used for inspection to port A.
- Cover ports B and C with the caps.






CAUTION:
- Do not apply a pressure 20 kPa {150 mmHg, 5.91 inHg} or more to the charcoal canister for 1 min. or more. Doing so will damage the charcoal canister.

3. Apply pressure (19.6 kPa {147 mmHg, 5.79 inHg}) through the hose, and verify that air does not leak from the charcoal canister.






Airflow Inspection

1. Remove the charcoal canister. (See Service and Repair.)

2. Perform the following procedure to verify the charcoal canister airflow.

Between port A and port B
- Plug the port C.

- Verify that there is airflow from port B.

- If there is no airflow, replace the charcoal canister. (See Service and Repair.)

Between port A and port C
- Plug the port B.
