A blinking tire pressure monitoring system (TPMS) indicator signifies a malfunction within the system itself, rather than simply low tire pressure. This is distinct from a solid, non-flashing light, which typically denotes that one or more tires are below the recommended pressure. The flashing indicates that a component of the TPMS, such as a sensor or the control module, is experiencing an issue, preventing the system from accurately monitoring and reporting tire pressures. For example, a sensor battery may be failing, or there could be interference disrupting the communication between the sensors and the vehicle’s computer.
Ignoring a flashing TPMS light can have serious consequences. While the vehicle may appear to be operating normally, the system’s inability to properly monitor tire pressure means that underinflated or overinflated tires could go unnoticed. Maintaining correct tire pressure is crucial for optimal fuel efficiency, tire wear, and overall vehicle safety. Historically, drivers relied on manual tire pressure checks. The development and implementation of TPMS technology were intended to provide a more consistent and reliable method of ensuring proper inflation, thereby mitigating risks associated with improper inflation.
