DIFFERENTIAL PRESSURE SENSOR ON-VEHICLE INSPECTION

PROCEDURE

  1. CHECK DIFFERENTIAL PRESSURE SENSOR ASSEMBLY

    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine and ECT / Data List / DPF Differential Pressure.

      Powertrain > Engine > Data List

      Tester Display

      DPF Differential Pressure

    5. Slide the clamp and disconnect the vacuum transmitting hose assembly from the differential pressure sensor assembly.

      Pressure

      Using SST, apply pressure to the differential pressure sensor assembly.

      09992-00242

    7. Check the pressure value of the differential pressure sensor assembly.

      Standard pressure

      Approximately the same pressure as the applied pressure is indicated on the GTS.

      Note:

      Perform the inspection within the range of 0 to 98 kPa (0 to 1.0 kgf/cm2, 0 to 14.2 psi).

      If the result is not as specified, check the differential pressure sensor circuit.
