Keeping an adequate tire pressure level is essential for handling, fuel efficiency, and tire durability. The tire pressure monitoring system or TPMS helps drivers practice proper tire care utilizing pressure gauges to let them know when their tiresinflation levels drop!

it's easy to forget about your INFINITI's TPMS, but it's a fundamental road safety component included in the majority of cars you spot on the road today! This system is so crucial that road safety laws in many countries require automakers to add it to all new vehicles— standard and high-end —sold in the U.S.

There are two main types of tire pressure monitoring systems—direct and indirect; the first one directly gauges the pressure inside each tire, and the second tracks tire RPMs to pinpoint imbalances between your tires.

If your vehicle has a direct tire pressure monitoring system, it leverages a Tire Pressure Monitoring System Sensor installed inside each tire to constantly monitor PSIs and alert the driver when pressure drops below a specific threshold. 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 installed incorrectly after a tire 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. In some cases a reset can fix the issues, but in many cases,

Unless you have a background in automotive care, removing and installing a new Tire Pressure Monitoring System Sensor is a challenging service best left to the pros. The process can involve letting the tire air out, 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 INFINITI's tires need to be properly inflated again, and, typically, re-balanced, too! Plus, depending on your INFINITI model and year, you may need to to take extra steps to make sure the new sensor is properly calibrated.
