• Ignition off.
• Carefully pressurize the fuel tank system to 7 kPa. The cock must be at right angles to the hoses.
  NOTE:

  Max 10 kPa.

  Check the fuel tank system: Spray soapy water from the EVAP canister to the canister purge (CP) valve. Also spray the line between the fuel tank and the EVAP canister shut-off valve. Also check the filler pipe and the fuel tank filler cap.

  It may be necessary to lower the fuel tank in order to fault-trace hoses and connectors on top of the fuel tank.

  Remedy the leakage.
