Circuit/System Verification

  1. Verify the following conditions do not exist in the EVAP system:
    • Loose, incorrect, missing, or damaged fuel fill cap
    • Loose, missing, or damaged service port schrader valve (if equipped)
    • Loose or damaged fuel tank pressure (FTP) sensor.
    • A damaged EVAP purge solenoid
    • Disconnected, incorrectly routed, kinked, or damaged EVAP pipes and hoses
    • A damaged EVAP vent valve or EVAP canister
      • If you find any of the above conditions, repair as necessary.
        NOTE: Refer to the J 41413-200 operation manual for detailed instructions.
  2. Remove the fuel fill cap. Connect the GE-41415-50 to the fuel tank filler neck. Connect the J 41413-200 to the GE- 41415-50.
  3. Calibrate the J 41413-200 Flow Meter to the correct leak orifice for the vehicle.
  4. Command the EVAP vent solenoid closed with a scan tool.
    NOTE: Larger volume fuel tanks and/or those with lower fuel levels may require several minutes for the floating indicator to stabilize.
  5. Activate the J 41413-200 and compare the flow meter's stable floating indicator position to the red flag. The floating indicator should be below the red flag.
    • If the floating indicator is above the red flag, test for a leak in the EVAP system.
    • If the floating indicator is below the red flag, test for a blockage or restriction in the EVAP system.
  6. If the vehicle passes the Circuit/System Verification test, then operate the vehicle within the conditions for running the DTC. You may also operate the vehicle within the conditions that are captured in the Freeze Frame/Failure Records List.
