(g)
If you have no Hand–Held tester:
Conclude forced driving of the VSV for the EVAP.
(1)
Stop the engine.
(2)
Disconnect the positive (+) and negative (–) leads
from the battery from the VSV terminals for the
EVAP.
(3)
Connect the VSV connector for the EVAP.
(h)
Disconnect the vacuum gauge from the EVAP service
port on the purge line.
(i)
Connect a pressure gauge to the EVAP service port on
the purge line.
(j)
Check the pressure.
(1)
Close off the air drain hose at the marked position
of the canister with a hose clipper or similar instru-
ment.
(2)
Add the pressure (13.5 – 15.5 in. Aq) from the EVAP
service port.
Pressure:
2 minutes after the pressure is added, the gauge
should be over 7.7 – 8.8 in.Aq.
HINT:
If you can not add pressure, you can conclude that the hose
connecting the VSV – canister – fuel tank has slipped off or the
VSV is open.
(3)
Check if the pressure decreases when the fuel tank
cap is removed while adding pressure.
HINT:
If the pressure dose not decrease when the filler cap is re-
moved, then you can conclude that the hose connecting the
service port to the fuel tank is blocked, etc.
(k)
Disconnect the pressure gauge from the EVAP service
port on the purge line.
