EVAP CANISTER
Check EVAP canister as follows:
1. Pinch the fresh air vent hose.
2. Blow air in port (A) and ensure free flow out of port (B).




Tightening Torque
Tighten EVAP canister as shown in the figure.
Make sure new O-ring is installed properly between EVAP canister and EVAP canister vent control valve.




FUEL TANK VACUUM RELIEF VALVE (Built into fuel filler cap)
1. Wipe clean valve housing.




2. Check valve opening pressure and vacuum.

Pressure: 15.3 - 20.0 kPa
(0.156 - 0.204 kg/sq.cm, 2.22 - 2.90 psi)

Vacuum: -6.0 to -3.3 kPa
(-0.061 to -0.034 kg/sq.cm, -0.87 to -0.48 psi)

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 incorrect fuel filler cap is used, the MIL may come on.




EVAPORATIVE EMISSION (EVAP) SHUT VALVE
- When pushing down the shutter inside the fuel filler opening, the EVAP shut valve is closed.
- When releasing the shutter, the valve is open.
1. Insert steel tube as shown in the figure.
2. Blow air from one side of the EVAP shut valve tube (a) or (b) and ensure that there is no air flow.
