Check Emissions System

Check Emissions System
2014 with 160K miles. Lots of highway driving. Yesterday evening I got this alert while driving home to Denver from Kansas City. Immediately I felt the engine struggle when accelerating. It would shake. No dealerships open on Sunday evening in KC. I decided to just get home. I did. If you are aware, the altitude goes up by 4000 feet and the car struggled whenever I had to climb even a little. I remember this with my previous car, VW Touareg. It turned out to be ignition coils with that one. I wonder what is wrong with this. It was not a fun drive.

At this time, the vehicle is running normally. The check emission system light is still on.

It appears that an oil sensor switch needs to be replaced. Google is Your friend. Here is a Youtube for a different model ,but switch will be in same location.. https://www.youtube.com/watch?v=GlorN9b4D9Y
Bought two of the parts from Amazon and it was a breeze.
Thanks.
