You are motor down the highway, music playing, when suddenly a modest symbol on your fascia get to flash unendingly. It is the Tire Pressure Monitoring System (TPMS) light, but rather of radiate steady, it is flick on and off. Seeing a nictitate tyre light can be alarming for any driver, especially when you are unsure if your tires are safe. While a firm light typically designate low air press in one or more of your tyre, a flashing light often bespeak a technical malfunction within the monitoring scheme itself. Understanding the difference between these two sign is important for maintaining vehicle guard and avoiding unnecessary wayside panic.
What Does a Blinking Tire Light Actually Mean?

This doings is the vehicle's way of narrate you that the TPMS detector network is ineffectual to communicate with the car's computer. Basically, the "brain" of the monitoring scheme has lose contact with one or more of the sensors situate inside your wheel forum. Without this connection, the system can not control your tyre pressing, coerce it to alert the driver that the guard lineament is presently inactive.
Common Causes of a TPMS Malfunction
Various component can lead to this sensor communicating failure. Because these sensor are mounted inside the tires and are exposed to extreme route weather, they are prostrate to specific types of vesture and tear. Here are the most common ground why you might see that wink image:
- Beat Sensor Battery: Most TPMS sensors are powered by minor, non-replaceable li battery that last between 5 and 10 age. Erstwhile the battery dies, the sensor can no longer transmit data.
- Physical Damage: Chuckhole, curbing, or junk can strike the sensor, damaging its home constituent or have it to detach from the valve stem.
- Corrosion: Exposure to route salt and wet can rust the sensor's electrical contacts or valve radical, leading to intermittent signal loss.
- Signal Interference: Rarely, aftermarket electronic devices plugged into the vehicle's ability outlets can create radio frequency noise that disrupt the detector sign.

| Light came on after tire rotation. | Sensor Relearn Required | Perform TPMS reset or relearn procedure. |
| Vehicle is over 7 age old. | Depleted Sensor Battery | Replace detector during next tyre change. |
