FUEL PUMP(for High Pressure) ON-VEHICLE INSPECTION

PROCEDURE


  1. CHECK FUEL PUMP OPERATION


    1. Check the fuel pressure.


      1. Connect the intelligent tester to the DLC3.

      2. Start the engine.

      3. Turn the tester on.

      4. Enter the following menus: Powertrain / Engine / Active Test / Control the Target Fuel Pressure / User Data / Fuel Press.

      5. Check that the fuel pressure fluctuates when the target fuel pressure changes.

        Tech Tips

        The Control the Target Fuel Pressure operation lowers the target fuel pressure by 12.5% or increases the target fuel pressure by 25%.

        Standard
        Fuel pressure fluctuates in accordance with tester operation.

        If the result is not as specified, replace the fuel pump or fuel delivery pipe assembly LH (fuel pressure sensor).

  2. INSPECT FUEL PUMP ASSEMBLY
