Keeping your car well-maintained is a great way to protect your investment, as well as your safety on the road. Tire pressure monitor systems alert you when tire pressure drops below safe levels. At Granbury Nissan, we provide genuine Nissan TPMS sensors designed for your Altima and Murano. Aftermarket sensors often fail to communicate properly with your vehicle's computer system or provide inaccurate readings.

How Tire Pressure Monitor Systems Work

TPMS sensors mount inside each tire to measure air pressure and sometimes temperature. Battery-powered sensors transmit data wirelessly to your vehicle's computer system continuously. The system compares pressure readings against manufacturer specifications stored in the computer. When pressure drops significantly below recommended levels, a warning light illuminates on your dashboard. Direct TPMS uses individual sensors while indirect systems monitor wheel speed differences. This technology prevents driving on dangerously underinflated tires that cause poor handling and increased wear.

What Causes TPMS Failure

Internal batteries in sensors have finite lifespans, typically lasting five to ten years before dying. Physical damage during tire mounting or dismounting breaks sensor housings or valve stems. Corrosion from moisture and road chemicals damages electronic components inside sensors. Cheap aftermarket sensors use inferior components that fail prematurely or provide unreliable data. Extreme temperature variations affect sensor accuracy and battery performance over time. Software incompatibility prevents aftermarket sensors from pairing correctly with factory systems.

Signs Your TPMS Needs Service

A constantly illuminated TPMS warning light indicates sensor failure or low battery condition. Intermittent warnings without actual pressure loss suggest failing sensor electronics. Inability to reset the system after tire service points to dead or damaged sensors. Most TPMS sensors require replacement every seven to ten years regardless of appearance. Replace failed sensors promptly to maintain awareness of tire conditions that affect safety. Keeping TPMS functional along with proper wheels maintenance ensures safe vehicle operation in all conditions.
