Why shell out big bucks for parts you're not sure will fit? Tire pressure monitor systems track the air pressure in each tire and alert you when levels fall outside safe operating ranges. These electronic safety systems prevent accidents caused by underinflated tires and help maintain fuel efficiency. The INFINITI Q70 and QX80 include tire pressure monitor systems that display real-time pressure readings on the dashboard.

Understanding Tire Pressure Monitor Systems

Tire pressure monitor systems use sensors mounted inside each wheel that measure air pressure and transmit data wirelessly to a receiver module. Each sensor contains a battery, pressure transducer, temperature sensor, and radio transmitter sealed in a weatherproof housing. The system activates when you start driving and continuously monitors pressure changes during operation. When pressure drops below the programmed threshold, the system illuminates a warning light on the instrument panel. Some systems display individual tire pressures while others only provide a general warning. These sensors mount directly to the valve stem or attach to the inner barrel of the wheel and communicate with the same computer network that controls wheels and other chassis systems.

Why Tire Pressure Sensors Stop Working

Tire pressure monitor systems fail when internal batteries deplete after five to ten years of continuous operation. Impact damage from rough roads or improper tire installation cracks sensor housings and ruins electronic components. Corrosion on valve stems and mounting hardware prevents proper sealing and causes air leaks. Temperature extremes affect battery performance and can cause premature sensor failure. Radio frequency interference from aftermarket electronics disrupts signal transmission.

Recognizing Tire Pressure Monitor System Failure

Replace tire pressure monitor sensors when the dashboard warning light remains illuminated despite correct tire pressures. Inaccurate pressure readings or sensors that stop transmitting data indicate component failure. Battery depletion typically affects all four sensors within a similar timeframe. Aftermarket tire pressure sensors often fail to program correctly with your vehicle's receiver module and may trigger false warnings or provide inaccurate readings. Genuine INFINITI tire pressure monitor sensors ensure proper communication protocols and accurate pressure measurement.
