Component Inspection

INSPECTION START
Do you have CONSULT-III?

Do you have CONSULT-III?

YES: GO TO 2.

NO: GO TO 3.
CHECK REFUELING EVAP VAPOR CUT VALVE
With CONSULT-III
1. Turn ignition switch OFF.
2. Remove fuel tank. Refer to "REMOVAL AND INSTALLATION ".
3. Drain fuel from the tank as follows:
  - Remove fuel feed hose located on the fuel gauge retainer.
  - Connect a spare fuel hose, one side to fuel gauge retainer where the hose was removed and the other side to a fuel container.
  - Drain fuel using "FUEL PUMP RELAY" in "ACTIVE TEST" mode with CONSULT-III.
4. Check refueling EVAP vapor cut valve for being stuck to close as follows.
  Blow air into the refueling EVAP vapor cut valve (from the end of EVAP/ORVR line hose), and check that the air flows freely into the tank.
5. Check refueling EVAP vapor cut valve for being stuck to open as follows.
  - Connect vacuum pump to hose end.
  - Remove fuel gauge retainer with fuel gauge unit.
    Always replace O-ring with new one.
  - Put fuel tank upside down.
  - Apply vacuum pressure to hose end [--13.3 kPa (--0.136 kg/cm³ , --1.93 psi)] with fuel gauge retainer remaining open and check that the pressure is applicable.
