My 2014 3.6L 1500 recently got P0520 and P0522 codes. After extensive research, it would seem it is most likely an oil pressure sensor gone bad. I would normally swap it out and see if it fixes my problem. However, in this case, I have a 3.6L and swapping it out seems like a PITA (i.e. removing the intake manifold, awkward location) AND I don't have the typical symptom everyone mentions (i.e. sensor showing max or min pressure). In my case, the sensor seems to be showing pressure continuously varying somewhere between 240 and 305 kPa (I think that is fairly normal?). See this video of my pressure sensor reading in action:

So the sensor seems to be working. I understand it might be a problem with the harness... but I don't really know how to check that. I did change my oil after the code came up and it didn't change anything. Oil level is ok.
Before I start taking everything apart, what would your approach be to this situation? I would love to hear what you think and what you would do. I don't really feel like taking the top of my engine apart if there is other stuff I should do first, please let me know! Thanks.
