Understanding Your Tire Pressure Monitor Systems
Most drivers understand what tire pressure monitor systems do, but fewer know how they wear down and need to be replaced. These electronic sensors track air pressure inside each tire and alert you when levels drop below safe thresholds. They mount inside the wheel assembly and transmit wireless signals to your dashboard display. Proper tire pressure affects fuel economy, tire wear, and vehicle handling.
How These Sensors Work
Tire pressure monitor systems use battery-powered sensors attached to the valve stem or mounted to the wheel's inner barrel. Each sensor measures pressure and temperature, then broadcasts this data to a receiver module in your vehicle. The system compares readings against factory specifications and triggers warning lights when pressure drops significantly. Nissan Sentra and Nissan Murano models include these sensors as standard safety equipment.
Why Sensors Stop Working
The internal batteries typically last five to ten years before dying completely. Corrosion from road salt damages sensor housings and electrical contacts. Physical damage occurs during tire mounting if technicians aren't careful with equipment. Temperature extremes can cause premature battery failure. Aftermarket sensors often use lower-quality batteries and cheaper components that fail sooner than genuine parts.
When to Replace Your TPMS
Replace sensors showing constant warning lights despite correct tire pressure. Dead battery symptoms include intermittent readings or complete signal loss. Plan replacement during tire changes to avoid extra labor costs. We also recommend checking sensor condition whenever you install new brake pads since wheels come off anyway. Genuine Nissan sensors are programmed specifically for your vehicle and integrate seamlessly with factory systems.
