Ensuring adequate tire pressure is vital for automotive handling, MPG, and your tire's structural integrity. The tire pressure monitoring system or TPMS helps motorists care for their cars and their tires using sensors to alert them to drops in tire inflation levels.

You may not think of your INFINITI's TPMS often, but it's a fundamental road safety component built-into most modern vehicles. As a matter of fact, the benefits of a TPMS are so remarkable that US law requires car manufacturers to add it to every new vehicle sold in the country ever since 2012.

There are two types of TPMS systems—direct and indirect; the former monitors pressure within the tire, while the other tracks your tirescircumferences by comparing each tire's rotation rates.

If your vehicle has a direct tire pressure monitoring system, it utilizes a Tire Pressure Monitoring System Sensor mounted within each tire to continuously measure tire pressure and notify the driver when air pressure decreases significantly. Like the rest of your car's parts, your Tire Pressure Monitoring System Sensor can malfunction if subjected to impact, rough use, age, or if installed incorrectly after a tire service.

Typically, the same dash light that lets you know when your tire pressure is low will become illuminated if there are issues within the tire pressure monitoring system itself. In some cases a reset can fix the issues, but in many cases,

Unless you have a background in automotive care, changing your own Tire Pressure Monitoring System Sensor is a challenging service best left to the pros. The process can involve letting the tire air out, unseating the tire bead from the wheel to remove the bad sensor, and carefully installing a new one. When the new sensor is in place, your INFINITI's tires need to be properly inflated again, and, typically, re-balanced, too! Also, depending on which INFINITI model and year you own, you will need to go the extra mile when calibrating the sensor.

Whether you choose to go to your local INFINITI service center for Tire Pressure Monitoring System Sensor replacements, or you want to try performing the replacement at home, one thing is for sure—having authentic Tire Pressure Monitoring System Sensor replacement parts is crucial.
