If your TPMS - Tire Pressure Monitoring Sensor - indicator is blinking or remains on after filling your tires to the proper pressure, replacement of tire pressure sensors will most likely be required before the warning light will turn off. To find sensors that fit your vehicle, just search for it below.
Warning Light Behavior
The TPMS warning lamp, pictured right, will illuminate if tire pressure is too low or part of the TPMS system has malfunctioned. The light can behave in two ways:
Blinking - This means the TPMS has malfunctioned. One or more sensors may have failed or lost communication with the ECU. Reasons for sensor failure may be a dead battery (in the unit), damage, or failure from natural wear and tear. Most sensors are rated to last 7 or 8 years.
Solid - A solid indicator light means that one or more tires is operating at an unsafe pressure. Check your tires!
Older Vehicles (before 2008)
The distinction between a solid and flashing TPMS indicator was mandated as part of the TREAD act in 2007. Vehicles with TPMS manufactured prior to the TREAD act will not necessarily follow the solid/flashing protocol as described above. Check your vehicle manual or ask an automotive professional to find out more.
