Component Inspection
NBS000MN
EVAP CANISTER
Check EVAP canister as follows:
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.
FUEL TANK VACUUM RELIEF VALVE (BUILT INTO FUEL FILLER CAP)
1.
Wipe clean valve housing.
2.
Check valve opening pressure and vacuum.
3.
If out of specification, replace fuel filler cap as an assembly.
CAUTION:
Use only a genuine fuel filler cap as a replacement. If an incor-
rect fuel filler cap is used, the MIL may come on.

EVAPORATIVE EMISSION SYSTEM
EVAP SERVICE PORT
Positive pressure is delivered to the EVAP system through the EVAP
service port. If fuel vapor leakage in the EVAP system occurs, use a
leak detector to locate the leak.
Removal and Installation
NBS000MO
EVAP CANISTER
Tighten EVAP canister as shown in the figure.
EVAP CANISTER VENT CONTROL VALVE
1.
Turn EVAP canister vent control valve counterclockwise.
2.
Remove the EVAP canister vent control valve.
Always replace O-ring with a new one.
How to Detect Fuel Vapor Leakage
NBS000MP
CAUTION:
●
Never 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 to the EVAP service port may cause a leak.
