INSPECTION
1. Connect a vacuum pump to the purge
control valve vacuum tube that goes to
the carburetor and apply vacuum
pressure of 45mm/Hg.
2. Connect a pressure pump to the tube
that goes to the charcoal canister and
apply pressure. The flow must be over
9.4 liters per minute and replace the
purge control valve with a new one if
the specified flow is not reached.
INSTALLATION
1. Install the purge control valve in the
reverse order of removal.
2. Route and reconnect the purge control
valve tubes properly and securely.
To prevent damage to the purge control
valve, do not use high air pressure
sources. Use a hand operated pressure
pump only.
Be careful not to bend, twist or kink the
tubes during installation.
