Why couldn’t I figure this out?

Dec. 10, 2020 (Chapter 18 Problem Solving and Making Decisions in my book)

Today I thought that I might need to put air in one of the tires on my vehicle. I decided to start my vehicle to see if the message was still on the screen. It was about 42 degrees outside and there was no message on the screen. This only seems to happen when the temperature falls below freezing. This weekend I'm going to have my vehicle inspected. I will talk to the car place about these messages that I get when the cold weather sets in. I'm hoping that after four years of owning this car that I might understand this sensor in the tires.
