EVAPORATIVE EMISSION SYSTEM

Inspection

INFOID:0000000009267329

1.

CHECK EVAP CANISTER

1. Block port (B).

2. Blow air into port (A) and check that it flows freely out of port (C).

3. Release blocked port (B).

4. Apply vacuum pressure to port (B) and check that vacuum pres-

sure exists at the ports (A) and (C).

5. Block port (A) and (B).

6. Apply pressure to port (C) and check that there is no leakage.

EVAP LEAK CHECK

Inspection

INFOID:0000000009267330

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 “WORK 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 the 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-41, "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.

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.

POSITIVE CRANKCASE VENTILATION

POSITIVE CRANKCASE VENTILATION

Inspection

INFOID:0000000009267331

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

placed over valve inlet.
Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Replace PCV valve. Refer to 

EM-44, "Exploded View"

.
