Nissan Altima 2007-2012 Service Manual: Evap leak check

Inspection

CAUTION: • Do not use compressed air or a high pressure pump.

• Do not exceed 4.12 kPa (0.042 kg/cm2, 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. To locate the EVAP leak, 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” of “WORK SUPPORT” mode with CONSULT-III.

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-622, "System Diagram".

1. To locate the EVAP leak, 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/cm2, 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-622, "System Diagram".
