Disengage the 2 claws of the retainer. Pull out the retainer and disconnect the fuel tank vent hose sub-assembly from the canister (charcoal canister assembly).
Note
Be sure to disconnect the fuel tank vent hose sub-assembly by hand.
Do not scratch or allow any foreign matter to get on the parts when disconnecting them as the fuel tube connector has O-rings that seal the pipe.
Do not bend, twist, pinch or kink the fuel tank vent hose sub-assembly.
Protect the disconnected parts by covering them with plastic bags after disconnecting the fuel tank vent hose sub-assembly.
Close the fuel tank vent hose sub-assembly using a hose plug or similar part.
| *a | Test Hose |
| *b | Air |
Connect a test hose to the canister (charcoal canister assembly).
Blow 8 kPa (0.1 kgf/cm2, 1.2 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).
Disconnect the test hose from the canister (charcoal canister assembly).

Connect a vacuum pump to the test hose.
Using the vacuum pump, apply vacuum and check that the vacuum pump needle does not move from its initial position.
Tech Tips
The vacuum pump needle may move when applying vacuum. If the vacuum pump needle 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).
Disconnect the vacuum pump from the test hose.
