DIFFERENTIAL PRESSURE SENSOR ON-VEHICLE INSPECTION


  1. CHECK DIFFERENTIAL PRESSURE SENSOR ASSEMBLY


    1. Connect the intelligent tester to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the intelligent tester on.

    4. Enter the following menus: Powertrain / Engine / Data List / DPNR Differential Pressure.

    5. Disconnect the No. 6 exhaust pipe air hose from the sensor.

    7. Check the pressure value of the sensor.

      Standard pressure
      Approximately the same pressure as the applied pressure indicated on the tester.

      Tech Tips

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