I have a 2012 Journey, and have been getting a Tire pressure system error since I had my tires replaced by Firestone. It changes, seemingly at random, which tire is in error. Initially it was the passenger rear then the passenger front, and now the drivers front. Sometimes it shows no error and all pressures are displayed correctly. Any thoughts on what is the culprit, and what kind of cost I'll be looking at to have it fixed?

Thanks,
Adam

 

I’d take it back to firestone and complain about it. They did something wrong.

 

I did that first thing... they spend 4 hours with it and said they couldn't find what was wrong with it, and I needed to take it to the dealership.

 

when the tpm light comes on; is the tpm light on solid or flashing

 

It starts out flashing then goes solid after a few seconds

 

flashing is a system problem....on solid is a low tire pressure reading
