Component Testing

  1. Pressurize the EVAP system to 5 inches H20.
  2. Compare the Fuel Tank Pressure sensor parameter with a scan tool to the J 41413-200 pressure/vacuum gauge. The scan tool FTP sensor parameter should be within 1 inch H20 of the pressure/vacuum gauge.
  3. Command the EVAP vent valve open with a scan tool.
  4. The scan tool Fuel Tank Pressure parameter should be 0 inches H20.
    • If the FTP sensor parameters do not respond to the change in pressure, replace the FTP sensor.
