I have driven the car around for a while. The screen still shows check system then shows the air pressure in each tire correctly. So I don't think it is the sensor in the tires. I called the tire shop and they said it would cost about $300 to replace all 4 sensors. They said their own brand does not work well with Mopars so they said to replace them with OEM sensors. But when I told him the the system was reading the tire pressure correctly, he seemed puzzled. So I am taking it in in the morning and they will do a free diagnostic to see if it is something else.

I will let you know the outcome when I get it.

Thanks for the help.
