I have an EMS 120 on my TECNAM  SIERRA P2002-RG. Sometimes the fuel pressure  changes from 0.25  bar to 0.15 bar; I think my fuel sensor for Rotax (Dynon part # 100411-000) is not working perfectly.
Without the 2 wires connected, the value of resistance between the two leads on the sensor is:

19 ohms at 0  bar (electric fuel pump OFF and engine OFF)
34 ohms at 0,25 bar (electric fuel pump ON and engine OFF)

Are these values of resistance corrected?

Regards

11 ohms is technically 0 psi/bar, but 34 ohms is about spot on.
