Tire Pressure Monitors – Transmitting LIVE” from a Car Tire Near You”

Brian England, Mon, Jan 16, 2017

For the several years now, automobiles have been produced with tire pressure monitoring systems. These systems warn the driver whenever one of the tires has lost pressure — before it becomes a danger. This early warning system can save you from having a completly flat tire, and over the years, these systems have saved many lives and prevented a lot of inconvienence.
Tire Pressure Sensor

Most of the tire pressure systems (TPS’s) have four or five tiny pressure sensoring electronics coupled with a radio frequency transmitter mounted inside the tire. They constantly send information to the automobile’s computer system. These electronic devices have to stand up to bumps, heat and rotation so they have to be very reliable. Inside each transmitter there is a tiny battery that lasts about 5 to 7 years or around 100,000 miles. This is quite a bit less than the life of the vehicle so there is a good chance that the sensors will have to be replaced. A good time to replace them is when the tires are changed. This cuts down on the labor cost because they can be installed fairly easily while the tire is off.

If your car was built after 2005 and you are having tires changed, we recommend that you ask for a price quote for replacing the sensors. Alternately, you can wait until your tire pressure sensors (TPS’s ) fail.  This will result in diaogostic charges and a larger labor charge to install one or more of the sensors. Each of these sensors can cost from $30 to $80 each.  TSP’s for some European automobile makes and models can cost significantly more.

If your tire pressure monitoring light comes on the first thing to do is to stop your vehicle in a safe place and check to see which tire is low. Use a tire pressure gauge to check each tire. If they all read close to what is recommended then you can continue to drive. In most cases, the recommended tire pressure is located on a label on the driver’s side door jam. If it is not there then check the vehicle handbook for the location. It is a good idea to be ready in advance in the event something like this occurs by knowing where your car’s tire pressure label is. You can also carry an tire pressure sensor guage, particularly if your car is getting close to 100,000 miles.
