The tire monitors consist of 4 transmitters that are part of the valve stem and a reciever.Either one of your tires are low of a transmitter has died.In irder to check it start by checking you tire pressures to see if they match whats on the door tag-usually the tire pressure gauges are off and read low so set them for about 35 psi and drive it 2 miles above 30 mph.After that you are going to need a special tool that will ping the transmitter and read the pressure directly form them so you can see if its reading at all.

You need to make sure that the tires are aired up correctly first-the system is very touchy about tire pressures being low-then in order to test the transmitters you need a special tool-I dont think any body rents them and they run from $300-$1,000 for the tool.If the tire pressures are good-try a local tire store since most tire shops have the tool now and more then likly the sensor-they can check to see which one needs to be replaced-they have a battery inside of them and a inertial switch that activates when the tire rolls and the transmitters/ sensors do go bad.

You only need to repace damaged or inopertive transmitters-like a light bulb-replace as they fail
