I was out flying today and suddenly I got a fuel pressure warning and my fuel pressure gauge had a big red X through it. Engine continued running, fuel flow normal, etc.
Previously, the fuel pressure readout was normal and steady, not the fluctuating readouts others have reported.
I thought I might have a bad connection but I checked that out and everything seems OK.
The pressure sensor is stamped with: "E1858" (I think means manuf. date of May 18, 2015) and "P4055-5025-1".
I measured resistances on my sensor and got:
red-black: open
red-green: variable between approx. 0.5K and 1.5K briefly then open
green-black: open
I checked the airframe cable and the red has +5v.
This looks like a sensor failure to me but is there anything I should check before getting a new one?
