DIFFERENTIAL PRESSURE SENSOR INSPECTION


  1. INSPECT DIFFERENTIAL PRESSURE SENSOR ASSEMBLY


    1. Disconnect the 2 differential pressure sensor assembly hoses.

    2. A01CH3A

      Connect SST to the differential pressure sensor assembly as shown in the illustration.

      SST
      09992-00242

    3. Turn the ignition switch to the ON position.

    4. A01CHKAE03

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

      Standard voltage
      Tester Connection Condition Specified Condition
      E22-27 (PEX) - E23-28 (E2) 0 kPa 0.75 V

      20 kPa (0.2 kgf/cm2, 2.8 psi)

      		 1.53 V

      100 kPa (1.0 kgf/cm2, 14 psi)

      		 4.65 V

    5. Disconnect SST from the differential pressure sensor assembly.

    6. Connect the 2 differential pressure sensor assembly hoses.

      Tech Tips

      Be sure to connect the hoses correctly.
