Hi.Evey one.
After 55 mint of flight oil pressure fluctuating between 80 PSL to 95 psi with all other indication normal.
After landing duplicate ground run c/out but problem did not duplicate.
All circuit security CX found sat.no abnormality found .
But I replace the sensor and plug and after that ground run c/out found sat.
My question is that why oil pressure fluctuating.max time oil pressure fluctuating .I have 8 a/c and this problem repeat again and again

Had the issue twice and both times it was a loose electrical connector at the pressure sensor.

I had this issue but it showed up to 7psi with the engine off so I cleaned up the connections (no change)
Grabbed an ammeter and checked the resistance (connector and ground on sensor). for me it was at 29 resistance than down to 10 when I tapped sensor body lightly with screwdriver. I have a backup ready to go, but for now it seems to be steady again.
