   Air conditioner switch	ON
   Head lamp switch	ON
   Rear window defogger switch	ON
   Engine speed	Approx. 3, 000 RPM
   Gear position	Any position other than P, N or R

10. Verify that EVAP control system pressure sensor value stays 0.1 V less than the value at idle speed (measured at step  6) for at least 1 second.

    Is the inspection result normal? 

    YES: INSPECTION END

    NO: Proceed to "DIAGNOSIS PROCEDURE ".
