Nissan Altima 2007-2012 Service Manual: Evap leak check
Inspection
CAUTION: • Never use compressed air or a high pressure pump.
• Never 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) to the EVAP service port may cause a leakage.
1. To locate the EVAP leakage, install EVAP service port adapter (commercial service tool) 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) and hose with pressure pump.
7. Locate the leakage using a leakage detector (commercial service tool). Refer to EC-1116, "System Diagram".
1. To locate the EVAP leakage, install EVAP service port adapter (commercial service tool) 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 leakage, 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) and hose with pressure pump.
5. Locate the leakage using a leakage detector (commercial service tool). Refer to EC-1116, "System Diagram".

control solenoid valve
Description
The EVAP canister purge volume control solenoid valve uses a ON/
OFF duty to control the flow rate of fuel vapor from the EVAP canister.
The EVAP canister purge volume control solenoid valve is
moved by ON/OFF pulses from the ECM. The longer the ON pulse,
the greater the amount o ...
