CAUTION / NOTICE / HINT

Note:

  • When replacing the ECM, the ECM needs Registration and Initialization (Click here).

  • After replacing the differential pressure sensor, the ECM needs initialization (Click here).

Tip:

  • When the ECM must be replaced, before replacing the ECM, perform the "Learning Values Save" function using the GTS. Then after installing the new ECM, perform all of the initialization/registrations for the "Learning Values Write" function by following the instructions shown on the GTS display.

  • Read freeze frame data using the GTS. 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, and other data from the time the malfunction occurred.

PROCEDURE

  1. CHECK HARNESS AND CONNECTOR (DIFFERENTIAL PRESSURE SENSOR - ECM)

    1. Disconnect the differential pressure sensor connector.

    2. Disconnect the ECM connector.

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

      Standard Resistance

      Tester Connection

      Condition

      Specified Condition

      C115-1 (VC) - C112-70 (VCPX)

      Always

      Below 1 Ω

      C115-2 (PEX) - C112-85 (PEX)

      Always

      Below 1 Ω

      C115-3 (E2) - C112-71 (EPEX)

      Always

      Below 1 Ω

      C115-1 (VC) or C112-70 (VCPX) - Body ground

      Always

      10 kΩ or higher

      C115-2 (PEX) or C112-85 (PEX) - Body ground

      Always

  2. CHECK HARNESS AND CONNECTOR (VC VOLTAGE)

    U122325E02

    1. Disconnect the differential pressure sensor connector.

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

      Standard Voltage

      Tester Connection

      Switch Condition

      Specified Condition

      C115-1 (VC) - C115-3 (E2)

      Ignition switch ON

      4.5 to 5.5 V

  3. CHECK DIFFERENTIAL PRESSURE SENSOR AIR HOSE CONNECTION

    1. Check the hose pipe from the exhaust emission system to the differential pressure sensor (for correct installation, sooting and leaks).

      OK

      Part is securely installed.

  4. READ VALUE USING GTS (ADAPTATION VALUE OF DIFFERENTIAL PRESSURE AT PARTICLE FILTER)

    Note:

    The EGR valve is closed during the test.

    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON and turn the GTS on.

    3. Enter the following menus: Powertrain / Engine and ECT / Data List / Adaptation Value of Differential Pressure at Particle Filter.

    4. Start the engine and warm it up until the engine coolant temperature is 80°C (176°F) or higher.

    5. Test 1

      1. Idle the engine for 2 seconds.

      2. Read the value for 10 seconds.

        OK

        With the ignition switch ON, "Adaptation Value of Differential Pressure at Particle Filter" value is within 3.5 kPa.

    6. Test 2

      1. Maintain the engine speed at 2000 rpm for 2 seconds.

      2. Maintain the engine speed at 2000 rpm and read the value for 10 seconds.

        OK

        With the ignition switch ON, "Adaptation Value of Differential Pressure at Particle Filter" value is within 7.5 kPa.

    7. Test 3

      1. With the engine running without load at approximately 3800 rpm, wait for 2 seconds.

      2. With the engine running without load at approximately 3800 rpm, read the value for 10 seconds.

        OK

        With the ignition switch ON, "Adaptation Value of Differential Pressure at Particle Filter" value is within 20 kPa.
