Keeping an adequate tire pressure level is essential for handling, fuel efficiency, and tire durability. The TPMS (short for tire pressure monitoring system) helps car owners care for their vehicles using sensors to alert them to drops in tire inflation levels.

It's easy to overlook the importance of your TPMS, but it's a vital vehicle component built-into most modern vehicles. As a matter of fact, the benefits of a TPMS are so remarkable that road safety laws in many countries require automakers to include it in all new passenger cars sold in the country since 2012.

TPMS come in two major varieties—direct and indirect; the first measures PSI-levels within each tire, and the second tracks tire RPMs to pinpoint imbalances between your tires.

If you have a direct TPMS, it leverages a Tire Pressure Monitoring System Sensor installed inside each tire 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.

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 simple reset can fix these issues, a Tire Pressure Monitoring System Sensor replacement is required.

Unless you really know your way around cars, replacing your INFINITI's Tire Pressure Monitoring System Sensor is a challenging service best left to the pros. The process can involve letting all the air out of the tire, unseating the tire from the rim to remove the faulty sensor, and mounting the replacement one. Once the new sensor is installed, the tires need to be inflated to appropriate pressure levels and, (usually) balanced again, to boot! Also, depending on the INFINITI model you're dealing with you may need to to take extra steps to make sure the new sensor is properly calibrated.
