Some of these would have 2 sensors, one for the computer and one for the pressure gauge. As the one for the computer is to tell it is within the pressure range otherwise it will turn on the service/check engine light on as there are OBC II which you can have reset at your local auto part store and get the codes at the same time to find out what is wrong.
