What is your question?
My dash is reading doors open and trunk open and low tire pressure I'm thinking it's a fuse do to the subs I had hooked up. All my doors are closed my trunk is closed and my tire pressure is good.
How long has your 2010 Mercury Grand Marquis had this problem?

Hello, You will need to identify the fuse according to the diagram in the owners manual, and if it is not there, google images will have tons of them. The tire pressure sensors on your vehicle are passed their shelf life, and are likely losing their battery charge. They tend to last 5-7 years, and after that is all just a nice bonus. They can cost anywhere from 25-60 dollars per sensor, and I recommend only replacing the ones which are not sending out a signal any longer. The tire pressure monitor control module could have a bad fuse as well, and that will be listed on the fuse panel diagram. I would love to just hand you the diagram, but there are hundreds of them posted online.
