2
gf/cm , 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
2
gf/cm , 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.

(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/cm
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
