CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR
1. Turn ignition switch OFF.
2. Remove EVAP control system pressure sensor with its harness connector connected from EVAP canister.
Always replace O-ring with a new one.
3. Install a vacuum pump to EVAP control system pressure sensor.
4. Turn ignition switch ON and check output voltage between ECM harness connector and ground under the
following conditions.
CAUTION:
• Always calibrate the vacuum pump gauge when using it.
• Do not apply below -93.3 kPa (-0.952 kg/cm
2
, -13.53 psi) or pressure over 101.3 kPa (1.033 kg/
cm
2
, 14.69 psi).
Is the inspection result normal?
YES

DTC DETECTION LOGIC
This diagnosis detects leaks in the EVAP line between fuel tank and EVAP canister purge volume control sole-
noid valve, using the negative pressure caused by decrease of fuel temperature in the fuel tank after turning
ignition switch OFF.
If ECM judges there are no leaks, the diagnosis will be OK.
CAUTION:
• Use only a genuine NISSAN fuel filler cap as a replacement. If an incorrect fuel filler cap is used, the
MIL may illuminate.
• If the fuel filler cap is not tightened properly, the MIL may illuminate.
• Use only a genuine NISSAN rubber tube as a replacement.

EVAP VERY SML LEAK
(Evaporative emission control
system leak)
• EVAP system has a leak.
• EVAP system does not op-
erate properly.
• Incorrect fuel tank vacuum relief valve
• Incorrect fuel filler cap used
• Fuel filler cap remains open or does not close.
• Foreign matter caught in fuel filler cap.
