2) Connect the 12 V battery to the terminals of the
EVAP system purge control solenoid valve and
check the air flow. If air flows out, the solenoid valve
is in normal condition.
3) Check the resistance between the terminals of the
EVAP system purge control solenoid valve. If the
resistance is not within the standard range, replace
the EVAP system purge control solenoid valve with a
new one.

Fuel Shut-Off Valve
Inspect the fuel shut-off valve body for damage. Inspect
the fuel shut-off valve operation in the following
procedures:
1) When air is blown into the fuel shut-off valve with its
side "A" positioned upward, the air can pass through
to the canister side.
2) When air is blown into the fuel shut-off valve with its
side "A" positioned sideways, the air cannot pass
through to the canister side. If the fuel shut-off valve
operates otherwise, it must be replaced.
WARNING
!
Gasoline and gasoline vapor is toxic. A small
amount of fuel remains in the fuel shut-off
valve when checking it. Do not swallow the
fuel when blowing the fuel shut-off valve.
