Fuel totalizer reset prior to flight. Flash data card installed before flight.
Attempted to do a second flight today. Filed flight plan to depart Manassas, but immediately after takeoff, the oil pressure gauge did it’s off-scale high anomaly again…Dammit…thought it was fixed. Aborted flight plan and immediately landed. This leaves only a few things left to try: Plug the oil pressure sensor wires into the manifold pressure gauge to see if that changes things or helps isolate, buy a new oil pressure gauge, and update the computer firmware. I’ve checked wiring at each connector end.
Time before: Engine 16.6, Total: 19.0
Time after: Engine 16.8, Total: 19.4
Flight time: 0.4
Good news is my takeoff and aborted departure saved me from having to wait out the rain cell on the ground in Warrenton while Manassas got drenched for an hour.
