Maintaining proper tire pressure is crucial for vehicle handling, fuel efficiency, and your tire's structural integrity. The tire pressure monitoring system (TPMS, for short) helps drivers practice proper tire care by leveraging sensors to let them know when their tires inflation levels drop!

It's easy to overlook the importance of your TPMS, but it's a vital vehicle component included in the majority of cars you spot on the road today! In fact, the TPMS is so consequential that road safety laws in many countries require automakers to include it in all new passenger cars sold in the country since 2012.

There are two main types of tire pressure monitoring systems— direct and indirect; the former monitors pressure within the tire, while the latter measures tire rotations to detect imbalances in your tirescircumferences.

If you have a direct TPMS, it leverages a Tire Pressure Monitoring System Sensor mounted inside of each of the tires to constantly monitor PSIs and activate a dashboard alert when something is amiss. Similar to other car systems, a Tire Pressure Monitoring System Sensor may glitch when subjected to impact, overuse, age, or if it's incorrectly installed following a tire replacement or service.

Most of the time, the dash light that notifies you of low tire air pressure levels will power on if there's something wrong with your INFINITI's tire pressure monitoring system sensor. Sometimes a simple reset can fix these issues, a Tire Pressure Monitoring System Sensor replacement is required.

Unless you're a seasoned at-home mechanic, replacing your INFINITI's Tire Pressure Monitoring System Sensor can be a complicated repair. Doing so usually includes detaching the old sensor from its valve, unseating the tire from the rim to remove the faulty sensor, and mounting the replacement one. Once the replacement sensor is mounted, your tires need to be reinflated and, typically, re-balanced, too! Plus, depending on your INFINITI model and year, you will likely need to go the extra mile when calibrating the sensor.

Whether you decide to visit your nearest INFINITI service center for tire pressure monitoring system services, or you want to try performing the replacement at home, one thing is certain—having authentic Tire Pressure Monitoring System Sensor replacement parts is crucial.
