When to Replace Your TPMS Sensor – A Complete Guide

Signs You Need to Replace Your TPMS Sensor

While cruising on a chilly morning, you might spot a warning light illuminating, signaling low tire pressure. This crucial alert is courtesy of your Tire Pressure Monitoring System (TPMS), and it’s a signal you should take seriously. Low pressure can potentially result in a tire blowout. However, in certain cases, especially if you have faith in your tire’s condition, the issue might not be with the tires themselves, but rather the TPMS sensor. But how do you interpret these warnings? When should you opt for roadside assistance, and when is it the right time to contemplate TPMS sensor replacement?

How to Identify a Faulty TPMS Sensor

Determining When to Replace a TPMS Sensor for Your Safety and Vehicle Efficiency: Here’s How:

  1. Battery Issues: TPMS sensors require battery power. An older vehicle battery or prolonged periods without driving can lead to sensor issues, especially in vehicles used in stop-and-go traffic.
  2. Sensor Malfunctions: If your tire pressure is within the recommended range, but the sensor triggers a warning light, it may be malfunctioning.
  3. Handling Differences: Should you notice handling changes like swerving or flat tires without a TPMS alert, the sensor might be failing to detect these crucial pressure drops.
  4. Fuel Economy Changes: An unexpected increase in fuel consumption can indicate driving on under-inflated tires without receiving an alert from a potentially faulty sensor.
  5. Post Tire Replacement: If the TPMS light turns on after getting new tires, it could be due to improper tire installation, sensor damage during the process, or a need for sensor resetting.

Consequences of Not Replacing a Bad TPMS Sensor

When to Replace TPMS Sensor: Consequences of Neglecting Replacement

  • Increased risk of tire failure on the road.
  • Poor fuel economy due to undetected under-inflated tires.
  • Higher wear and tear on tires, leading to premature replacement needs.
  • TPMS Sensor Lifespan and Replacement Costs

Normally, TPMS sensors are designed to last for 5 to 10 years. However, it’s important to note that their batteries are non-replaceable. So, when a sensor’s battery reaches the end of its life, the entire unit must be replaced. The cost of replacing all four TPMS sensors can vary, typically falling in the range of $200 to $800. The exact cost depends on the make and model of your vehicle.

Your Guide to Replacing TPMS Sensors

Replacing your vehicle’s TPMS sensors doesn’t have to be a challenge. If you notice any of the signs mentioned above, it’s time to consider tpms sensor replacement. Consult your vehicle’s manual for specific instructions or seek professional help to ensure proper handling and functionality.

Get Roadside Assistance for Your TPMS Needs

When you encounter TPMS issues, it’s crucial not to delay seeking professional assistance. Companies such as STTC offer around-the-clock emergency road service for commercial trucks. Keep in mind that driving with a malfunctioning TPMS sensor poses risks, so it’s wise to address the problem promptly.

Knowing when to replace the TPMS sensor is integral to maintaining your vehicle’s health and your safety on the road. Keep an eye out for the signs of a bad tpms sensor and take action accordingly. Regular checks and maintenance are the best defenses against unexpected tire-related incidents.
