Keeping an adequate tire pressure level is essential for handling, fuel efficiency, and tire health. The TPMS (short for tire pressure monitoring system) helps drivers practice proper tire care using sensors to let them know when their tires inflation levels drop!
You may not think of your INFINITI's TPMS often, but it's a valuable piece of technology included in the majority of cars you spot on the road today! In fact, the TPMS is so consequential that US law requires car manufacturers to include it in all new passenger cars sold in the country since 2012.
TPMS come in two major varieties— direct and indirect; the former monitors pressure within the tire, and the second tracks tire RPMs to pinpoint imbalances between your tires.
If your INFINITI has a direct TPMS, it leverages a Tire Pressure Monitoring System Sensor mounted inside of each of the tires to constantly monitor PSIs 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, overuse, 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 light up if there are issues within the tire pressure monitoring system itself. In some cases a reset can fix the issues, a Tire Pressure Monitoring System Sensor replacement is required.
Unless you have a background in automotive care, replacing your INFINITI's Tire Pressure Monitoring System Sensor can be a complicated repair. The process can involve unscrewing the faulty sensor from the corresponding valve, dismounting the tire bead from the rim to remove the faulty sensor, and carefully installing a new one. Once the replacement sensor is mounted, your tires need to be reinflated and, in most cases, re-balanced! Also, depending on which INFINITI model and year you own, you may need to to take additional steps to calibrate the sensor.
Whether you choose to go to your local INFINITI service center for tire pressure monitoring system services, or you want to try performing the replacement at home, one thing is for sure—getting authentic Tire Pressure Monitoring System Sensor parts is your best bet.
