      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 and ground under the following conditions.
      ECM Condition [Applied vacuum kPa (kg/cm2 , psi)] Voltage
      Connector + -
      Terminal
      F11 43 68 Not applied 0.5 - 4.6 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.
      • Do not apply below -93.3 kPa (-0.952 kg/cm2 , -13.53 psi) or pressure over 101.3 kPa (1.033 kg/cm2 , 14.69 psi).
