Oil Pressure

Recommended Posts

I have a 912ULS with Keller 456180 oil pressure transducer.  It is connected to a Dynon SV 1000/700 and EMS.  The equipment has been in operation for 100+ Hrs with out a problem.


On a recent XC the OP went up to 73/74 and after landing it ws 53.  When I booted the avionics with the engine stopped the OP came up showing 53.  On engine start up the OP remained at 53.  After shutdown the OP was still at 53.  Disconnected the transducer and got a red X.  Cleaned the transducer electronic connection with no change to indication.


I am sure I know the answer but thought I would ask if anyone has a solution instead of ordering a new transducer?
