EVAP CANISTER
Check EVAP canister as follows:
1.
Pinch the fresh air hose.
2.
Blow air into port A and check that it flows freely out of port B .
Tightening Torque
Tighten EVAP canister as shown in the figure.
Make sure new O-ring is installed properly between EVAP can-
ister and EVAP canister vent control valve.
FUEL TANK VACUUM RELIEF VALVE (BUILT INTO FUEL FULLER 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.
How to Detect Fuel Vapor Leakage
EBS00MOS
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.
WITH CONSULT-II
1.
Attach the EVAP service port adapter securely to the EVAP service port.
2.
Also attach the pressure pump and hose to the EVAP service port adapter.
3.
Turn ignition switch “ON”.
4.
Select the “EVAP SYSTEM CLOSE” of “WORK SUPPORT
MODE” with CONSULT-II.
5.
Touch “START”. A bar graph (Pressure indicating display) will
appear on the screen.
6.
Apply positive pressure to the EVAP system until the pressure
indicator reaches the middle of the bar graph.
7.
Remove EVAP service port adapter and hose with pressure
pump.
