EVAP LEAK CHECK
InspectionINFOID:0000000009462466
CAUTION:
• Do not use compressed air or a high pressure pump.
• Do not exceed 4.12 kPa (0.042 kg/cm
2, 0.6 psi) of pressure in EVAP system.
NOTE:
• Do not start engine.
• Improper installation of EVAP service port adapter [commercial service tool: (J-41413-OBD)] to the EVAP
service port may cause a leak.
1.EVAP LEAK CHECK
With CONSULT
1. Install EVAP service port adapter [commercial service tool: (J- 41413-OBD)] and pressure pump to EVAP service port.
2. Turn ignition switch ON.
3. Select the “EVAP SYSTEM CLOSE” in “WOR K SUPPORT” mode of “ENGINE” using CONSULT.
4. Touch “START”. A bar graph (Pressure indicating display) will appear on the screen.
5. Apply positive pressure to the EVAP system until t he pressure indicator reaches the middle of the bar
graph.
6. Remove EVAP service port adapter [commercial service tool: (J-41413-OBD)] and hose with pressure
pump.
7. Locate the leak using a leak detector [commercial service tool: (J-41416)]. Refer to EC-62, "EVAPORATIVE EMISSION SYS-
TEM : System Description".
Without CONSULT
1. Install EVAP service port adapter [commercial service tool: (J- 41413-OBD)] and pressure pump to EVAP service port.

EVAP LEAK CHECK
2. Apply battery voltage between the terminals of EVAP
canister vent control valve to make a closed EVAP
system.
3. To locate the leak, deliver positive pressure to the EVAP system 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 EVAP service port adapter [commercial service tool: (J-41413-OBD)] and hose with pressure
pump.
5. Locate the leak using a leak detector [commercial service tool: (J-41416)]. Refer to EC-62, "EVAPORATIVE EMISSION SYS-
TEM : System Description".

1.CHECK PCV VALVE
With engine running at idle, remove PCV valve from rocker cover. A
properly working valve makes a hissing noise as air passes through
it. A strong vacuum should be felt immediately when a finger is
