  1. CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR
    1. Turn ignition switch OFF.
    2. Remove EVAP control system pressure sensor with its harness connector.

      Always replace O-ring with a new one. 

    3. Install a vacuum pump to EVAP control system pressure sensor.
    4. Turn ignition switch ON and check output voltage between ECM harness connector terminals under the following conditions.
    VOLTAGE SPECIFICATION

    ECM Condition
    [Applied vacuum kPa (kg/cm2 , psi)]    		 Voltage (V)
    Connector + -
    Terminal Terminal
    M107 102 112 Not applied 1.8 - 4.8
    -26.7 (-0.272, -3.87) 2.1 to 2.5 lower than above value
    CAUTION:
    • Always calibrate the vacuum pump gauge when using it.
    • Never apply below -93.3 kPa (-0.952 kg/cm2 , -13.53 psi) or pressure over 101.3 kPa (1.033 kg/cm2 , 14.69 psi).

    Is the inspection result normal? 

    YES: INSPECTION END

    NO: Replace EVAP control system pressure sensor
