A Guide To TPMS Service Kit: Types, Use, & More

All About TPMS Service Kits

All vehicles from 2008 onwards come equipped with a tire pressure monitoring system (TPMS). However, TPMS sensors wear out over time. Even if the sensors don’t wear out, some parts of the TPMS are damaged. Therefore, a TPMS service kit is a set of components that are used to service or repair a TPMS sensor.

Let’s go through the details of the TPMS service kits but before that learn its importance.

What Is A TPMS Service Kit?

A TPMS service kit comes with various components that are used to service, maintain or repair a TPMS sensor. These components may vary depending on the specific kit, but some common items that may be included are:


Valve cores:

These are small components that are inserted into the valve stem of the tire. They are responsible for maintaining proper pressure and allowing air to enter or exit the tire.

Valve caps:

These are small covers that fit over the valve stem to protect the valve core from dirt and debris.

Valve stems:

These are the metal or rubber components that the valve core and valve cap attach to. They are responsible for holding the tire pressure sensor in place.
Grommets: These are small rubber components that are used to seal the valve stem hole in the wheel.
Nuts and washers: These are used to secure the tire pressure sensor to the valve stem.
Sealing washers: These are used to ensure a tight seal between the tire pressure sensor and the valve stem.


These are used to seal the tire pressure sensor to the valve stem.


This is used to lubricate the valve stem and other components during installation to prevent damage and ensure proper function.

A TPMS service kit can be used to maintain or repair a tire pressure monitoring system, which helps to ensure that the tires are properly inflated and safe to use.

Types Of TPMS Service Kits

Different TPMS manufacturers provide their service kits. Each service kit comes with different components. That said, here are a few types of TPMS service kits:


TPMS Service Kit TypeComponents Included
Valve Stem KitValve stem, valve core, valve cap, grommet, nut and washer
Sensor Service KitO-ring, seal, valve core, cap, nut and washer, lubricant
Battery Replacement KitBattery, O-ring, seal, nut and washer
Tool KitTPMS activation tool, torque wrench, valve core tool, valve stem puller

Note that some TPMS service kits can include more components and vary depending on the manufacturer.

The steps for using a TPMS service kit vary depending on the specific kit being used, but the general process is as follows:

  • Determine the type of kit needed for the repair or maintenance task at hand.
  • Remove the tire from the vehicle.
  • If replacing the valve stem or sensor, remove the old one using the appropriate tools.
  • Install the new valve stem or sensor according to the manufacturer\’s instructions, using the components included in the service kit.
  • Use a torque wrench to tighten the nut and washer to the manufacturer\’s specified torque.
  • If the valve core needs to be replaced, install the new one using the appropriate tool.
  • Also, install the new valve cap to protect the valve core from dirt and debris.
  • Inflate the tire properly.
  • Install the tire back on the car

Importance Of TPMS Kits

The TPMS (Tire Pressure Monitoring System) actively monitors the air pressure in the tires and notifies the driver if the pressure falls below the recommended level.. A TPMS service kit is necessary because it allows you to maintain or repair the TPMS sensor in your vehicle. Also, the service kit is essential because driving with underinflated tires can lead to several problems.

A TPMS service kit helps ensure that the TPMS sensor is accurately installed, sealed to the valve stem, and functioning correctly. It can help to improve your vehicle\’s fuel efficiency, tire wear, handling and braking performance, and overall safety on the road. A TPMS service kit helps with compliance with regulations.

By maintaining proper tire pressure with the help of a TPMS service kit, you can have peace of mind knowing that your vehicle is operating at its best. Therefore, you can buy TPMS sensors and service kits from the leading TPMS manufacturer and ensure optimum vehicle performance.
