What is TPMS?

The TPMS (Tire Pressure Monitoring System) is designed to measure air pressure and alert the driver when the pressure in one or more of the tires is below 25% of the manufacturer’s recommended pressure. There are two types of systems, direct and indirect. The far more utilized and more accurate Direct System uses sensors that are attached to each wheel. These sensors communicate with the vehicle’s TPMS module. The Indirect System typically utilizes the vehicles antilock braking system’s (ABS) speed sensors to monitor pressure.

Can I Replace the TPMS Sensor by Myself?

Replacing TPMS sensors requires a tire changer. The wheel should be rebalanced after installation. If you or your friend have access to a tire changer and balancer, along with the proper tools for installation of the sensors and the relearn procedure, you could attempt to replace a sensor. However, we recommend you have a reputable repair shop do the installation and relearn.

What to do when your TPMS WARNING LIGHT on?

1. If your TPMS light comes on, and stays on, that means at least one of your tires is at low-pressure level. After knowing that, you should check the pressure of all of the tires with a gauge and add air or service the tire(s) accordingly.

2. If TPMS light goes on and off, it could be caused by fluctuating temperatures in the tire. This could be repaired by checking the pressure of all of the tires and adding air to any tire that is low.

3. If the light flashes for approximately 60 to 90 seconds every time you start your car and then the light stays on, you should inspect the TPMS sensor and maybe need to replace a new TPMS in most cases.

Why do I Need the Tire Pressure Monitoring System Sensor (TPMS) in my Vehicle?

As of the model year 2008, the United States Department of Transportation (through NHTSA) requires an installation of a Tire Pressure Monitoring System to all new passenger cars, multipurpose passenger vehicles, trucks, and buses that have a gross vehicle weight rating of 10,000 lbs. or less (except those vehicles with dual wheels on an axle). The legislation requiring TPMS was passed in reaction to Congressional hearings on vehicle rollover deaths caused, in part, by vehicles with underinflated tires.
