  1. CHECK FOR FUEL PUMP OPERATION AND INSPECT FOR FUEL LEAK

  2. CHECK FUEL PRESSURE

Топливная Система -- Проверка Без Снятия С Автомобиля



1. CHECK FOR FUEL PUMP OPERATION AND INSPECT FOR FUEL LEAK

  1. Check fuel pump operation.

    1. Connect the intelligent tester to the DLC3.

    2. Turn the ignition switch on (IG) and turn the intelligent tester main switch on.

      ПРИМЕЧАНИЕ:
      Do not start the engine.

    3. Select the following menus: Powertrain / Engine / Active Test / Control the Fuel Pump /Speed.

    4. Check for pressure in the fuel inlet tube from the fuel line. Check that sound of fuel flowing in the fuel tank can be heard. If no sound can be heard, check the integration relay, fuel pump, ECM and wiring connector.

  1. Inspect for fuel leak.

    1. Check that there are no fuel leaks anywhere on the system after performing maintenance. If there is a fuel leak, repair or replace parts as necessary.

  1. Turn the ignition switch off.

  1. Disconnect the intelligent tester from the DLC3.



2. CHECK FUEL PRESSURE

  1. Discharge the fuel system pressure (See page Нажмите здесь).

  1. Using a voltmeter, measure the battery voltage according to the value(s) in the table below.

    Standard voltage:
    Tester Connection
    		Condition
    		Specified Condition
    Positive terminal - Negative terminal
    		Ignition switch off
    		11 to 14 V

  1. Disconnect the cable from the negative (-) battery terminal.

  1. Disconnect the fuel hose from the fuel main tube (See page Нажмите здесь).

  1. Install SST (pressure gauge) using other SST as shown in the illustration.

    SST
    09268-31012(09268-41500,90467-13001,95336-08070)
    09268-45014(09268-41200,09268-41220,09268-41250)

  1. Wipe up any gasoline.

  1. Connect the cable to the negative (-) battery terminal.

  1. Connect the intelligent tester to the DLC3.

  1. Select the following menus: Powertrain / Engine / Active Test / Control the Fuel Pump / Speed.

  1. Measure the fuel pressure.

    Fuel pressure:
    304 to 343 kPa (3.1 to 3.5 kgf*cm2, 44.1 to 49.7 psi)
    1. If the fuel pressure is greater than the standard value, replace the fuel pressure regulator.
    2. If the fuel pressure is less than the standard value, check the fuel hoses and connections, fuel pump, fuel filter and fuel pressure regulator.

  1. Disconnect the intelligent tester from the DLC3.

  1. Start the engine.

  1. Measure the fuel pressure at idle.

    Fuel pressure:
    304 to 343 kPa (3.1 to 3.5 kgf*cm2, 44.1 to 49.7 psi)

  1. Stop the engine.

  1. Check that the fuel pressure remains as specified for 5 minutes after the engine stops.

    Fuel pressure:
    147 kPa (1.5 kgf*cm2, 21 psi) or more
    If the fuel pressure is not as specified, check the fuel pump or fuel injector.

  1. After checking the fuel pressure, disconnect the cable from the negative (-) battery terminal and carefully remove SST to prevent gasoline from splashing.

  1. Reconnect the fuel tube to the main fuel tube (fuel tube connector).

  1. Install the No. 1 fuel pipe clamp to the fuel tube connector.

  1. Check for fuel leaks (Step 1).
