When keeping your car, truck, or SUV in tip-top shape, Regal Nissan is always there for you. Tire pressure monitor systems use sensors mounted inside each wheel to track air pressure continuously. These electronic components alert you when tire pressure drops below safe levels. Proper TPMS function helps prevent tire damage and improves fuel efficiency. We carry genuine Nissan TPMS sensors that integrate perfectly with your vehicle's computer system.

How TPMS Monitors Your Tire Pressure

TPMS sensors measure air pressure inside each tire and transmit this data wirelessly to your vehicle's computer. The system compares actual pressure against programmed specifications and triggers dashboard warnings when pressure drops significantly. Each sensor contains a battery, pressure transducer, and radio transmitter housed in a compact unit. Your Leaf and Armada both rely on these sensors to provide real-time pressure information. The system works constantly while driving, checking pressure multiple times per minute to detect gradual leaks or sudden pressure loss from road hazards. Proper tire pressure also affects brake performance and vehicle stability.

Why TPMS Sensors Fail

TPMS sensors stop working when their internal batteries deplete after five to ten years of operation. Impact damage from potholes can crack sensor housings or damage internal components. Corrosion from moisture exposure degrades electrical connections and sensor accuracy. Improper tire mounting procedures crush sensors or damage valve stems. Aftermarket sensors often use incompatible transmission frequencies that your vehicle's computer can't recognize. Generic replacement sensors may lack proper programming capabilities for Nissan-specific systems.

When TPMS Sensors Require Replacement

Replace TPMS sensors when the dashboard warning light stays illuminated after proper tire inflation. Sensors typically need replacement every seven to ten years as batteries wear out. Any sensor damaged during tire service must be replaced immediately. If your system shows constant errors or intermittent readings, sensor replacement is necessary. We recommend replacing all sensors simultaneously to prevent future individual failures. Enjoy fast shipping from Regal Nissan's team, with a fair return policy for your peace of mind.
