Can the oil pressure error be trigged by a bad oil sensor...

See 1st post and subsequent followup.

To sum it up, I believe it was the oil sensor.
Since the 1st incident, it has come up 2 more times.
Yesterday, driving all day. Then stopped for 20 minutes. Started back up and got oil pressure error. Shut it down....checked oil level, started back up. No errors and another 1hr + drive back home.

So in total, since the 1st incident, 2X low oil and 1X oil pressure.
The oil sensor is on my todo list -- just need to finish my spring sh1t list ontop of pressure washing the exterior of the house and all that sch1tz. However, don't want to be throwing parts at it, without a good direction. I feel it's just the oil level sensor but don't see how this would have trigged the low oil pressure error..Then again, maybe it's just ~electricals~ that trickle effect
