Update. The link wasn’t too informative and P2190 isn’t the usual oxy sensor code even though the description is describing rich bank two. The car ran perfect, strong as ever. I cleared the code and it kept coming back. I saw a new Motorcraft oxy sensor on ebay for around $60 so I grabbed it. The car is 2015 and close to 60k miles but I have B2B coverage for another 3 years. But the warranty has a $100 deductible. Lucky it was bank 2 and only took 15 minutes to change. After a half hour drive the code came back. So I disconnected the battery for a couple hours and it’s been fine since. Not mentioned because I thought I could have been a coincidence, early on the day of the CEL, I got a “no key detected”. I had that happened once before because I carry a couple different fobs in a small coin purse in my cargo pocket and I guessed the signal got blocked. We stopped for gas but I didn’t want to shut the engine off just in case I still had the fault and didn’t want to risk a no start. I know gassing up while with the engine running can mess with the evap system. So bottom line, I don’t know which caused the fault but all is good now.

Our cars have a backup slot in the event the battery in the fob goes bad, you can still start the car. This portion of the fob does not rely on the internal battery to operate. It's either in the glove box or the center consol. If you have the rectangle fob, glove box. If you have the pointed fob it's in the center consol.
I totally forgot about that. Mind goes blank when in panic mode.
