Tomorrow I am going to do some troubleshooting to figure out why the oil pressure shows 49 psi prior to starting the engine. I suspect it is a failed oil pressure sensor.
I have reviewed SI 912-020R2 which explains a change in the oil pressure sensor part no. 956413 (new part) for engines with S/N 5,651,797 and higher. My engine should have the new oil pressure sensor which operates on basis of current variation instead of the resistance variation. I have not verified this. Nevertheless, I am planning to power up the avionics then disconnect the wire to the sensor . If the gauge still reads 49 psi I figure the sensor is faulty.
Wondering if any else has experienced this situation and has any other advice on troubleshooting this problem.
