Component Inspection

  1. CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR
    1. Turn ignition switch OFF.
    2. Remove EVAP control system pressure sensor with its harness connector. Refer to " REMOVAL AND INSTALLATION ".

      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 REFERENCE CHART

    ECM Condition [Applied vacuum kPa (kg/cm2 , psi)] Voltage
    Connector + -
    Terminal Terminal
    E16 86 (EVAP control system pressure sensor signal) 96 (Sensor ground) Not applied 1.8 - 4.8 V
    -26.7 (-0.272, -3.87) 2.1 to 2.5 V 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. Refer to " REMOVAL AND INSTALLATION ".
