How to Calibrate the Tire Pressure Monitoring System?

In 2008, the NHSA passed a law that required all light trucks and cars, from 2008 and forward to have a tire pressure sensor system. This was due to the fact that there had been a high accident rate among cars with underinflated and overinflated tires.

The system sometimes needs to be calibrated in order to function properly. Here are some tips on how to calibrate the tire pressure monitoring system on your vehicle.

Tire Pressure Sensors
  • Type of TPMS. You will need to find out if your car uses a direct system or an indirect system. If your car has a direct system, the tire pressure systems can be reset by using a reset button or following the steps that are listed in your owner’s manual. If you have an indirect system, the system can only be reset by scanning tool or a magnet that you get from the dealer or one that you purchased yourself. There are some systems that have a reset button that is located inside the glove box. This will need to be pressed down, while the ignition is on and pressed for 3 seconds.

  • Inflate the tires. All tires will need to be properly inflated. You will be resetting your sensors back to nothing, so all of your tires must have the right air weight in. If not, you run the risk of the air sensors not being calibrated properly.

  • Do a battery check. These sensors are battery powered. You will want to make sure that the battery is not dead. It is a good idea to get a new battery once every 5 years. Occasionally, this will require that the entire sensor is replaced because the battery is built-in.

  • Transponder recalibration. The transporter is located on the wheel and each will have its own transponder. When you rotate the new tires the TPMS will have to learn their new location. You will find how to do this procedure in your vehicle manual or online. In some cases, the valve stems may also be the tire pressure sensors. If this is the case, when you get new tires, you want to get new valve stems.

  • Using a scanning tool. Look in your owner’s manual and find the TPM S reprogramming procedure and follow the instructions if you have the scanning tool.

  • Using a magnet method. Place your key in the ignition of your vehicle, turn on but do not start the ignition. Press the unlock and lock buttons. Listen for the initial chirp and place in magnet on the valve stems. You will hear the horn chirps. You will need to verify the pressure settings and if this is not correct you will need to restart the procedure.
