DIFFERENTIAL PRESSURE SENSOR(for DPF) ON-VEHICLE INSPECTION

PROCEDURE

1. CHECK DIFFERENTIAL PRESSURE SENSOR ASSEMBLY

   
   

   1. Connect the GTS to the DLC3.

   2. Turn the engine switch on (IG).

   3. Turn the GTS on.

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

   5. for Bank 1:

      Disconnect the No. 1 air hose from the differential pressure sensor.

   6. for Bank 2:

      Disconnect the No. 3 air hose from the differential pressure sensor.

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

   8. Check the pressure value of the sensor.

      Standard pressure
      Approximately the same pressure as the applied pressure is 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).

   9. for Bank 1:

      Connect the No. 1 air hose to the differential pressure sensor.

   10. for Bank 2:

       Connect the No. 3 air hose to the differential pressure sensor.
