Nissan Sentra 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.EVAP LEAK CHECK
With CONSULT
- Install EVAP service port adapter [commercial service tool: (J-
41413-OBD)] and pressure pump to EVAP service port.

- Turn ignition switch ON.
- Select the “EVAP SYSTEM CLOSE” in “WORK SUPPORT” mode of “ENGINE” using
CONSULT.
- Touch “START”. A bar graph (Pressure indicating display) will appear on
the screen.
- Apply positive pressure to the EVAP system until the pressure indicator
reaches the middle of the bar
graph.
- Remove EVAP service port adapter [commercial service tool:
(J-41413-OBD)] and hose with pressure
pump.
- Locate the leak using a leak detector [commercial service tool:
(J-41416)]. Refer to EC-49, "EVAPORATIVE EMISSION SYSTEM
: System Description".

Without CONSULT
- Install EVAP service port adapter [commercial service tool: (J-
41413-OBD)] and pressure pump to EVAP service port.

- Apply battery voltage between the terminals of EVAP canister vent
control valve to make a closed EVAP
system.
- 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).
- Remove EVAP service port adapter [commercial service tool:
(J-41413-OBD)] and hose with pressure
pump.
- Locate the leak using a leak detector [commercial service tool:
(J-41416)]. Refer to EC-49, "EVAPORATIVE EMISSION SYSTEM
: System Description".
