EVAP Control System Pressure Sensor

  1. Remove EVAP control system pressure sensor with its harness connector connected from EVAP canister.

    Always replace O-ring with a new one. 

  2. Install a vacuum pump to EVAP control system pressure sensor.
  3. Turn ignition switch ON and check output voltage between ECM terminal 102 and ground under the following conditions.
    Applied vacuum kPa (kg/cm2 , psi) Voltage V
    Not applied 1.8 - 4.8
    -26.7 (-0.272, -3.87) 2.1 to 2.5V lower than above value
    CAUTION:
    • Always calibrate the vacuum pump gauge when using it.
    • Do not apply below -93.3 kPa (-0.952 kg/cm2 , -13.53 psi) or pressure over 101.3 kPa (1.033 kg/cm2 , 14.59 psi).
  4. If NG, replace EVAP control system pressure sensor.
