2. 2

   The power supply to the differential pressure sensor

3. 3

   The differential pressure sensor itself

1. 1

   Inspect

   Check the wiring and connections to the differential pressure sensor for damage, corrosion, or loose connections.

2. 2

   Test

   Verify the power supply to the differential pressure sensor using a multimeter, ensuring it is within the specified range.

3. 3

   Replace

   If the differential pressure sensor is found to be faulty, replace it with a compatible component.
