Component Testing Procedure

EVAP CANISTER
Check EVAP canister as follows:
1. Pinch the fresh air vent hose.
2. Blow air in port (A) and check that it flows freely out of port (B).




TIGHTENING TORQUE
Tighten EVAP canister as shown in the figure.




FUEL TANK VACUUM RELIEF VALVE
1. Wipe clean valve housing.
2. Suck air through the cap. A slight resistance accompanied by valve clicks indicates that valve A is in good mechanical condition. Note also that, by further sucking air, the resistance should disappear with valve clicks.
3. Blow air on fuel tank side and ensure that continuity of air passage exists through valve B.
4. If valve is clogged or if no resistance is felt, replace 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 check that there is no air flow.
