Everything You Need to Know About TPMS Sensors

SENSOR

Introduction

Tire Pressure Monitoring Sensors (TPMS) play a crucial role in vehicle safety by ensuring that your tires maintain proper inflation. If you've ever seen that little yellow tire pressure light on your dashboard, you may have wondered what it means and how to deal with it. This article will cover everything you need to know about TPMS sensors, their importance, how they work, and whether you should replace them when getting new wheels and tires.

What is a TPMS Sensor?

A TPMS sensor is an electronic device installed in your vehicle's tires to monitor tire pressure levels. It sends real-time data to your car’s onboard system, alerting you if the pressure is too low or too high. Most vehicles manufactured after 2007 are required by law to have TPMS sensors.

Why Are TPMS Sensors Important?

  • Safety: Proper tire pressure reduces the risk of accidents caused by blowouts.

  • Fuel Efficiency: Underinflated tires can reduce fuel efficiency and increase fuel consumption.

  • Tire Longevity: Maintaining the right tire pressure prevents uneven wear and extends tire life.

  • Compliance with Regulations: Many states require TPMS sensors, making them necessary for vehicle inspections.

Common Issues with TPMS Sensors

  1. TPMS Light On: If your TPMS light stays on, it means one or more tires have low pressure, or the sensor needs recalibration.

  2. Sensor Failure: Over time, TPMS sensors wear out and may need to be replaced.

  3. Compatibility Issues: Some aftermarket wheels may not be compatible with your vehicle’s TPMS system

How to Replace TPMS Sensors

Step 1: Purchase the Right TPMS Sensor

  • Different vehicle manufacturers use different types of TPMS sensors.

  • Ensure you get the correct one for your car.

  • Check TPMS Sensors on Amazon

Step 2: Install the Sensor

  • Remove the tire and locate the TPMS sensor.

  • Unscrew the old sensor and replace it with the new one.

  • Secure the sensor and reassemble the tire.

Step 3: Calibration

Some vehicles automatically recognize new TPMS sensors, while others require manual programming. You may need a TPMS reset tool or a visit to the dealership.

Cost of TPMS Sensor Replacement

  • Average Cost: $50 - $100 per sensor

  • Installation Cost: $40 - $60 per sensor (if done by a mechanic)

  • Total Cost: $200 - $400 for a complete replacement

If a shop charges more than $150 per sensor, it’s best to look for another option to avoid overcharging.

Can You Reuse Old TPMS Sensors?

While it may be tempting to reuse old TPMS sensors, it is not always recommended. Sensors in OEM wheels are designed for a specific thickness, which may not be compatible with aftermarket wheels. Using old sensors can lead to inaccurate readings or failure.
