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.

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-
.
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.

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
