On-Vehicle Inspection

  1. CHECK FOR FUEL PUMP OPERATION AND INSPECT FOR FUEL LEAK 
    1. Check fuel pump operation.
      1. Connect the Techstream to the DLC3.
      2. Turn the ignition switch to ON and turn the Techstream on.
        NOTE: Do not start the engine.
      3. Enter 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 sounds of fuel flowing from the fuel tank can be heard. If no sounds can be heard, check the integration relay, fuel pump, ECM and wiring connectors.
    2. Inspect for fuel leaks.
      1. Check that there is no fuel leakage after performing maintenance anywhere on the fuel system. If there is a fuel leak, repair or replace parts as necessary.
    3. Turn the ignition switch off.
    4. Disconnect the Techstream from the DLC3.
  2. CHECK FUEL PRESSURE 
    1. Discharge fuel system pressure (See FUEL SYSTEM ).
    2. Using a voltmeter, measure the battery voltage according to the value(s) in the table below.

      Standard Voltage 

      STANDARD VOLTAGE

      Tester Connection Switch Condition Specified Condition
      Positive terminal - Negative terminal Ignition switch off 11 to 14 V
    3. Disconnect the cable from the negative (-) battery terminal.
    4. Disconnect the fuel hose from the fuel main tube (See FUEL SYSTEM ).
    5. 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) 

    6. Clean up any spilled gasoline.
    7. Connect the cable to the negative (-) battery terminal.
    8. Connect the Techstream to the DLC3.
    9. Enter the following menus: Powertrain / Engine / Active Test / Control the Fuel Pump / Speed.
    10. Measure the fuel pressure.

      Fuel pressure: 

      304 to 343 kPa (3.1 to 3.5 kgf*cm 2  , 44 to 50 psi) 

      • If the fuel pressure is greater than the standard value, replace the fuel pressure regulator.
      • If the fuel pressure is less than the standard value, check the fuel hoses and connections, fuel pump, fuel filter and fuel pressure regulator.

    11. Disconnect the Techstream from the DLC3.
    12. Start the engine.
    13. Measure the fuel pressure at idle.

      Fuel pressure: 

      304 to 343 kPa (3.1 to 3.5 kgf*cm 2  , 44 to 50 psi) 

    14. Stop the engine.
    15. Check that the fuel pressure remains as specified for 5 minutes after the engine stops.

      Fuel pressure: 

      147 kPa (1.5 kgf*cm 2  , 21 psi) or more 

      If the fuel pressure is not as specified, check the fuel pump or fuel injector.

    16. After checking the fuel pressure, disconnect the cable from the negative (-) battery terminal and carefully remove SST to prevent gasoline from spraying.
    17. Reconnect the fuel tube to the main fuel tube (fuel tube connector).
    18. Install the No. 1 fuel pipe clamp to the fuel tube connector.
    19. Check for fuel leaks (Step 1).

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
