Oscar Avalle Posted November 13, 2023 Report Share Posted November 13, 2023 Yesterday during my run up on my JPI 900 oil pressure went dead... A big red cross across oil pressure. Obvioulsy no flying. But any idea what may have happened? The sensor went dead? connection? or de unit? Any advice more than welcome.

ArtVandelay Posted November 13, 2023 Report Share Posted November 13, 2023 Probably pressure sensor on the firewall or the wiring into the display.I would start from the engine, wiring of the sensor can be broken by careless maintenance, then check the connections of the sensor wires to the wiring harness.The wiring into the display is the last thing I would check unless you have had some work done behind the panel recently. 2 Quote Link to comment Share on other sites More sharing options...
Aerodon Posted November 13, 2023 Report Share Posted November 13, 2023 Most likely the transducer or the wiring going to it. Here's a 'cheat', swap the fuel pressure and oil pressure transducers, see if the red X goes away or moves? Don't start the engine with transducers swapped, they are different pressure ratings. 1 Quote Link to comment Share on other sites More sharing options...
Oscar Avalle Posted November 17, 2023 Author Report Share Posted November 17, 2023 Actually, it was the unit... 2 Quote Link to comment Share on other sites More sharing options...
