Maintaining proper tire pressure is crucial for vehicle handling, gas mileage, and tire health. The tire pressure monitoring system (TPMS, for short) helps motorists care for their cars and their tires using sensors to notify them when one or more of their tires pressure drops past a specific threshold.
It's easy to overlook the importance of your TPMS, but it's a fundamental road safety component found in most vehicles today. In fact, the TPMS is so consequential that automakers have been required to add it to every new vehicle sold in the country ever since 2012.
There are two main types of tire pressure monitoring systems—direct and indirect; the first one directly gauges the pressure inside each tire, while the other tracks your tires circumferences by comparing each tire's rotation rates.
If you have a direct TPMS, it utilizes a Tire Pressure Monitoring System Sensor mounted inside of each of the tires to continuously measure tire pressure and notify the driver when air pressure decreases significantly. Similar to other car systems, a Tire Pressure Monitoring System Sensor may glitch if it is damaged due to impact, rough use, age, or if it's incorrectly installed following a tire replacement or 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. Sometimes a system reset can be a quick fix, but more often than not,
Unless you really know your way around cars, removing and installing a new Tire Pressure Monitoring System Sensor can be a tricky repair to do at-home. Doing so usually includes detaching the old sensor from its valve, unseating the tire from the rim to remove the old sensor, and carefully installing a new one. Once the replacement sensor is mounted, the tires need to be inflated to appropriate pressure levels and, (usually) balanced again, to boot! Plus, depending on the INFINITI model you're dealing with you will likely need to take additional steps to calibrate the sensor.
Whether you choose to go to your local INFINITI service center for TPMS-related services, or if you plan on attempting this service at home, one thing is certain—getting Tire Pressure Monitoring System Sensor replacement parts that fit your model and year is the best decision. Select your INFINITI model and year to find parts that fit your INFINITI JX35 2013-2020 and INFINITI QX60 2013-2020. See the What This Fits tab for more information.
