  1. Check the pressure value of the differential pressure sensor.

    Standard pressure:
    Approximately the same pressure as the applied pressure is indicated on the GTS.
    NOTICE:
    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.

  1. Remove SST from the differential pressure sensor.

  1. Connect the air hose to the differential pressure sensor, and slide the clamp to secure the hose.

  1. Install the No. 1 engine cover sub-assembly.
