How to Detect Fuel Vapor Leakage
NGEC0019S10
CAUTION:
쐌 Never use compressed air or a high pressure pump.
쐌 Do not start engine.
쐌 Do not exceed 4.12 kPa (0.042 kg/cm
2
, 0.6 psi) of pressure
in EVAP system.
NOTE:
Improper installation of adapter to the service port may cause
a leak.
With CONSULT-II
1) Attach the EVAP service port adapter securely to the EVAP
service port.
2) Also attach the pressure pump and hose.
3) Turn ignition switch “ON”.
4) Select the “EVAP SYSTEM CLOSE” of “WORK SUPPORT
MODE” with CONSULT-II.
5) Touch “START”. A bar graph (Pressure indicating display) will
appear on the screen.
6) Apply positive pressure to the EVAP system until the pressure
indicator reaches the middle of the bar graph.
7) Remove the EVAP service port adapter and hose with pres-
sure pump.
8) Locate the leak using a leak detector. Refer to “Evaporative
Emission Line Drawing”, EC-37.
Without CONSULT-II
1) Attach the EVAP service port adapter securely to the EVAP
service port and pressure pump with pressure gauge to the
EVAP service port.
2) Apply battery voltage to between the terminals of both EVAP
canister vent control valve and vacuum cut valve bypass valve
to make a closed EVAP system.
3) To locate the leak, deliver positive pressure to the EVAP sys-
tem until pressure gauge points reach 1.38 to 2.76 kPa (0.014
to 0.028 kg/cm
2
, 0.2 to 0.4 psi).
4) Remove the EVAP service port adapter and hose with pres-
sure pump.
5) Locate the leak using a leak detector. Refer to “EVAPORATIVE
EMISSION LINE DRAWING”, EC-37.
