DESCRIPTION

The fuel injectors are located on the intake manifold, They inject fuel into the cylinders based on the signals from the ECM.

DTC No. DTC Detection Condition Trouble Area

P0208

 Current is not applied to the fuel injector more than 10 times with the engine running. (1 trip detection logic)

  • Open or short in fuel injector circuit

  • Fuel injector

  • ECM

MONITOR DESCRIPTION

The ECM monitors the injection control of the fuel injector. If a malfunction is detected in the fuel injector circuit, the ECM cancels the injection control for the corresponding cylinder and turns on the MIL.

Tech Tips

Read freeze frame data using the intelligent tester. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.

PROCEDURE


  1. CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0201, P0202, P0203, P0204, P0205, P0206, P0207 OR P0208)


    1. Connect the intelligent tester to the DLC3.

    2. Turn the engine switch on (IG).

    3. Start the engine.

    4. Turn the tester on.

    5. Enter the following menus: Powertrain / Engine / DTC.

    6. Read DTCs.

  2. CHECK FUEL INJECTOR FOR PORT INJECTION (POWER SOURCE VOLTAGE)


    1. A001EC2E02
      *1 Front view of wire harness connector: (to Fuel Injector)

      Disconnect the fuel injector connector.

    2. Turn the engine switch on (IG).

    3. Measure the voltage according to the value(s) in the table below.

      Standard voltage
      Tester Connection Switch Condition Specified Condition
      J5-2 - Body ground Engine switch on (IG) 11 to 14 V
      I5-2 - Body ground Engine switch on (IG) 11 to 14 V
      J6-2 - Body ground Engine switch on (IG) 11 to 14 V
      I6-2 - Body ground Engine switch on (IG) 11 to 14 V
      J7-2 - Body ground Engine switch on (IG) 11 to 14 V
      I7-2 - Body ground Engine switch on (IG) 11 to 14 V
      J8-2 - Body ground Engine switch on (IG) 11 to 14 V
      I8-2 - Body ground Engine switch on (IG) 11 to 14 V

    CHECK AND REPAIR HARNESS OR CONNECTOR (INJ FUSE - INJECTOR)

    OK

  3. CHECK HARNESS AND CONNECTOR (ECM - FUEL INJECTOR)


    1. Disconnect the E2 and E4 ECM connectors.

      *1 Front view of wire harness connector: (to Fuel Injector for Port Injection)
      *2 Rear view of wire harness connector: (to ECM)

    2. Disconnect the fuel injector connector.

    3. Measure the resistance according to the value(s) in the table below.

      Standard resistance (Check for open)
      Tester Connection Condition Specified Condition
      J5-1 - E4-17 (#10) Always Below 1 Ω
      I5-1 - E2-11 (#20) Always Below 1 Ω
