Ensuring adequate tire pressure is vital for automotive handling, MPG, and tire durability. The tire pressure monitoring system (TPMS, for short) helps motorists care for their cars and their tires utilizing pressure gauges 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 valuable piece of technology included in the majority of cars you spot on the road today! 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 main types of tire pressure monitoring systems—direct and indirect; the former monitors pressure within the tire, while the other tracks your tires circumferences 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 inside of each of the tires to continuously gauge PSIs and alert the driver when pressure drops below a specific threshold. Like the rest of your car's parts, your Tire Pressure Monitoring System Sensor can fail if it is damaged due to impact, overuse, age, or if it's incorrectly installed following a tire replacement or service.

In most cases, 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 system reset can be a quick fix, but in many cases,

Unless you have a background in automotive care, replacing your INFINITI's Tire Pressure Monitoring System Sensor is a challenging service best left to the pros. Doing so usually includes letting all the air out of the tire, dismounting the tire bead from the rim to remove the old sensor, and installing the new one. When the new sensor is in place, your tires need to be reinflated and, (usually) balanced again, to boot! Additionally, depending on which INFINITI model and year you own, you may need to to take additional steps to calibrate the sensor.
