Circuit/System Testing

  1. Ignition OFF, remove the fuel fill cap. Connect the J 41415-30:  Adapter to the fuel tank filler neck. Connect the J 41413-200:  EEST to the J 41415-30:  Adapter.
  2. Ignition ON, seal the EVAP system using the scan tool Purge/Seal function.
  3. Pressurize the EVAP system with nitrogen to 9.33 mm/Hg (5 in/H2O). Compare the scan tool Fuel Tank Pressure Sensor parameter to the J 41413-200:  EEST pressure/vacuum gage. Verify the scan tool FTP sensor parameter is within +/-0.9 mmHg (+/-0.5 in.H2O) of the pressure/vacuum gauge.
    • If not within the specified range, replace the B150 FTP sensor.
  4. Command the Q13 EVAP vent solenoid valve OPEN with a scan tool. Verify the scan tool FTP sensor parameter is -0.9 to +0.9 mmHg (-0.5 to +0.5 in.H2O).
