What Does Tire Pressure Sensor Fault Mean? By Sensor Guides

A tire pressure sensor fault refers to a malfunction or issue with the tire pressure monitoring system in a vehicle. It indicates that the system may not accurately monitor tire pressure, which can compromise safety, handling, and fuel efficiency.

In the modern era of automotive technology, tire pressure sensors have become integral to vehicle safety and performance. These sensors are responsible for monitoring tire pressure and alerting drivers to any deviations from the recommended levels. However, encountering a tire pressure sensor fault can confuse and concern vehicle owners. 

This article will delve into the meaning and implications of a tire pressure sensor fault, understanding its causes, signs, troubleshooting methods, and preventive measures.

What is Tire Pressure Sensor?

Before we explore the concept of a tire pressure sensor fault, it’s essential to clearly understand what a tire pressure sensor is and how it functions. 

A tire pressure sensor is a small electronic device installed in each tire that continuously measures and transmits tire pressure data to the vehicle’s onboard computer system. 

Its purpose is to ensure drivers are aware of deviations from the recommended tire pressure, which can affect handling, safety, and fuel efficiency.

What are common causes of Tire Pressure Sensor Faults?

What Does Tire Pressure Sensor Fault Mean

Several factors can contribute to a tire pressure sensor fault. Understanding these causes can help vehicle owners identify potential issues and take appropriate action. The most common causes of a tire pressure sensor fault include:

  1. Battery Depletion: Tire pressure sensors are equipped with batteries that can eventually deplete over time. When the battery power runs low, it can lead to a sensor fault.
  2. Sensor Damage or Malfunction: Physical damage or internal malfunctioning of the sensor can result in inaccurate readings or a complete sensor failure.
  3. Interference from External Factors: Interference from electromagnetic fields, radio signals, or other external factors can disrupt the communication between the sensors and the vehicle’s onboard system, triggering a fault.

Signs and Symptoms of a Tire Pressure Sensor Fault

When a tire pressure sensor fault occurs, there are several signs and symptoms that vehicle owners should be aware of. These include:

Warning Light Illumination

The most common indication of a tire pressure sensor fault is the illumination of the tire pressure warning light on the vehicle’s dashboard.

Inaccurate or Inconsistent Tire Pressure Readings

Drivers may notice discrepancies between the displayed tire pressure readings and the tire pressure.

Failure to Receive Sensor Signals

If the vehicle’s onboard computer system fails to receive signals from one or more tire pressure sensors, it indicates a fault in the sensor(s).

Troubleshooting and Resolving Tire Pressure Sensor Faults

When faced with a tire pressure sensor fault, there are several troubleshooting steps that vehicle owners can take to address the issue. These include:

  1. Checking Tire Pressure Manually: Using a reliable tire pressure gauge, manually check the pressure in all tires to verify if there is an actual pressure issue.
  2. Inspecting and Replacing Sensor Batteries: If the fault is caused by depleted sensor batteries, replacing them can resolve the issue and restore proper sensor functionality.
  3. Seeking Professional Assistance for Sensor Replacement or Recalibration: If the fault persists or the sensors are damaged, it is advisable to seek professional assistance for sensor replacement or recalibration.

Preventive Measures for Maintaining Tire Pressure Sensors

Prevention is key to avoiding tire pressure sensor faults and ensuring optimal performance. Here are some preventive measures vehicle owners can take:

  1. Regular Tire Maintenance and Inspections: Maintain proper tire inflation by regularly checking and adjusting tire pressure. Additionally, inspect tires for signs of damage or wear.
  2. Protecting Sensors from Damage: Avoid rough driving conditions, curbs, and potholes to prevent physical damage to the sensors. Be cautious when replacing tires to prevent accidental sensor damage.
  3. Monitoring Battery Life and Replacing as Needed: Keep track of the sensor batteries’ lifespan and replace them proactively before they deplete completely.

Can you drive with a tire pressure sensor fault?

It is technically possible to drive with a tire pressure sensor fault, but it is not recommended. A tire pressure sensor fault means the system may not accurately monitor the tire pressure, potentially leading to unsafe driving conditions. 

Incorrect tire pressure can affect handling, braking, and fuel efficiency, compromising vehicle safety and performance. It is crucial to address the issue promptly to ensure proper tire inflation. 

Ignoring a tire pressure sensor fault increases the risk of tire damage, blowouts, and accidents. It is best to have the fault diagnosed and repaired by a professional to maintain optimal safety on the road.


A tire pressure sensor fault can be unsettling for vehicle owners, but understanding its meaning and implications is crucial. By recognizing the common causes, signs, and troubleshooting methods associated with tire pressure sensor faults, drivers can take appropriate action to ensure safety, optimize vehicle performance, and extend tire lifespan.

Regular maintenance, proactive monitoring, and promptly addressing faults are key to maintaining the functionality and reliability of tire pressure sensors. By staying informed and proactive, vehicle owners can enjoy the benefits of accurate tire pressure monitoring and enhance their overall driving experience.
