1. INSPECT CHARCOAL CANISTER ASSEMBLY
(a) Visually check the charcoal canister for cracks or damage.
If cracks or damage are found, replace the charcoal canister assembly.
(b) Check charcoal canister operation.
(1) With the purge port closed, blow 1.67 kPa (17.0 gf/cm2, 0.24 psi) of air into the vent port, and check that air flows from the air inlet port.
If the result is not as specified, replace the charcoal canister assembly.
(2) With the vent port closed, blow 1.10 kPa (11.2 gf/cm2, 0.16 psi) of air to the air inlet port, and check that air flows from the purge port.
If the result is not as specified, replace the charcoal canister assembly.
(c) Check for air leakage.
(1) Remove the air hose between ports A and B.
(2) Connect SST (pressure gauge) to the vent port of the charcoal canister.
SST 09992-00242 (3) While holding port B, with the purge port and the air inlet port closed and port A open, apply 19.6 kPa (0.2 kgf/cm2, 2.81 psi) of pressurized air into the vent port, then confirm that pressure is retained for 1 minute.
If the result is not as specified, replace the charcoal canister assembly.
(d) Check the leak detection pump.
(1) Remove the detection pump from the charcoal canister.
(2) Check that air flows from port A to B and then C.
If the result is not as specified, replace the charcoal canister assembly.
(3) Connect the positive (+) lead to terminal 7 and the negative (-) lead to terminal 6.
(4) Check that the valve is closed.
If the result is not as specified, replace the charcoal canister assembly.
