So I figured out the issue and yes it makes me feel like an idiot, but the results do confirm a specific suspicion ihad regarding the pressure readings I was seeing from the sensor. I will post the before and after readings. But I thought it was odd that I was seeing negative pressure readings coming from the sensor.
So here is what I did wrong. When I installed the sensor I installed the hoses to the wrong ports on the sensor, so it was obviously seeing very incorrect information, which would explain why i was getting the erratic/intermittent reading on the sensor and a sensor fault. I had a feeling that the negative pressure I was seeing was some sort of sign that the sensor was receiving incorrect data. That is why I double checked the hose routing. On this sensor the hose diameter is the same, so it is possible to mix them up, but I also noticed that where the metal line and the rubber line connect, there is an indent where the metal line should rest. This line had a mark on it where it rested before and I noticed the mark on the metal line was not exactly in the same spot as before, maybe 2 or 3mm back. So this again made me think.
Anyway long story short. I switched the hoses and after a 25 minute drive, no MIL, no codes. So I think the issue has been resolved.
Below are the original readings I had of the pressures, which showed a negative reading. And then the new readings that show positive hPa numbers, which makes more sense to me. So I guess it is a good idea to look at those numbers to see if something looks off.
Thanks to everyone who passed their knowledge on and despite me figuring the issue out, i learned more about ways to diagnose some issues.
