Tire sensors are essential components in modern vehicles, particularly those equipped with TPMS (Tire Pressure Monitoring System). These sensors continuously monitor the air pressure inside your tires, alerting you when there’s an issue. Over time, these sensors may need replacement due to wear, damage, or battery failure.
Why Tire Sensors Need Replacing
Several factors contribute to the need for replacing tire sensors. Common issues include:
Battery Failure: Most tire sensors are powered by small batteries that can wear out after several years.
Physical Damage: Road debris, impacts, or incorrect tire installation can physically damage sensors.
Sensor Wear: Over time, the sensor may degrade, and the sensor readings may become inaccurate.
When the sensor fails, the dashboard warning light typically illuminates, indicating that a replacement is necessary.

How to Know Your Tire Sensor is Bad
One of the most reliable ways to determine if your tire sensor is malfunctioning is by using OBD-II scanner. These devices can connect to your vehicle’s onboard diagnostics system and provide specific error codes that can point to a faulty tire sensor. When a tire sensor fails, the TPMS light on your dashboard will likely illuminate, but a car scanner will provide more detailed information.
Common error codes related to tire sensor issues include:
-
C0031: This indicates a faulty left front tire sensor, meaning the sensor might be damaged or its communication with the system is lost.
-
C0032: Refers to a right front tire sensor issue, often caused by damage or battery failure in the sensor.
-
C0033: Points to a left rear tire sensor failure, signaling either a bad sensor or wiring issue.
-
C0034: Relates to a right rear tire sensor, which could be malfunctioning due to a physical issue or low battery.
-
C0035: This code means there’s a general TPMS communication issue, which might indicate more than one sensor is having trouble connecting.
By using a car scanner to check for these error codes, you can accurately pinpoint which sensor is malfunctioning and decide whether to replace it or seek professional repair.
Cost of Replacing a Tire Sensor
The cost of replacing a tire sensor depends on various factors, including the make and model of your vehicle, the type of sensor, and labor costs. On average, the cost of replacing a tire sensor can range from $50 to $150 per sensor, with some high end models or specialized sensors potentially costing more. Here's a breakdown of the factors affecting the price:
Type of Sensor:
Direct TPMS sensors, which measure the actual air pressure inside the tires, are usually more expensive than indirect TPMS systems, which estimate tire pressure based on the wheel rotation speed.
Aftermarket vs. OEM Sensors: Original Equipment Manufacturer (OEM) sensors are generally pricier than aftermarket options, but they may be more reliable and compatible with your vehicle.

Labor Costs:
Labor charges vary by location, but replacing a tire sensor typically involves removing the tire, replacing the sensor, and reprogramming the system to recognize the new sensor. Labor costs may range from $20 to $50 per tire.
Vehicle Make and Model:
Luxury vehicles or vehicles with complex systems may have higher replacement costs. For example, high performance cars or certain European brands might require specialized sensors that cost more to replace.
When to Replace a Tire Sensor
Tire sensors typically last between 5 and 10 years, depending on usage and driving conditions. You should replace your tire sensor if:
- You see the TPMS light on your dashboard and the issue persists after checking tire pressure.
- The sensor fails to communicate with the system, even after resetting or reprogramming.
- Your tires have been changed or repaired, and the sensor is damaged during the process.
Can You Replace Just One Sensor
While it’s technically possible to replace just one faulty sensor, it is often recommended to replace all tire sensors at once, especially if they are close to the end of their lifespan. Replacing only one sensor could lead to imbalances in the system, and you might experience issues with sensor communication or calibration in the future.
DIY or Professional Replacement
Replacing a tire sensor is a job that requires some mechanical knowledge, particularly in removing and reassembling tires. If you have experience with tire maintenance, you might opt for a DIY replacement. However, for most drivers, it is advisable to hire a professional mechanic or visit a tire service center.
Additional Costs to Consider
Besides the sensor itself, there are other costs that may be involved when replacing a tire sensor:
Sensor Programming: Some vehicles require the TPMS system to be reprogrammed after replacing a sensor. This process can cost anywhere from $30 to $60, depending on the make and model of the vehicle.
Tire Mounting: If the tires need to be removed for the sensor replacement, you may need to pay additional fees for tire mounting and balancing, which typically costs between $15 and $30 per tire.
Where to Get Tire Sensors Replaced
You can have tire sensors replaced at various locations, including:
Dealerships: Dealerships typically use OEM sensors and may charge higher labor rates.
Tire Shops: Many tire shops offer competitive pricing and may be able to provide both sensors and labor at a more affordable rate.
Auto Parts Stores: If you choose to replace the sensor yourself, you can purchase sensors from auto parts stores, either in person or online.
Conclusion
The cost of replacing a tire sensor can vary, but on average, you can expect to pay between $50 and $150 per sensor, with labor costs ranging from $20 to $50 per tire. While replacing just one sensor is an option, replacing all four sensors at the same time can help avoid future issues.
FAQs
How long do tire sensors last?
Tire sensors typically last between 5 and 10 years, depending on driving conditions and usage.
Can I replace a tire sensor myself?
Yes, if you have the necessary skills, you can replace the tire sensor yourself. However, most people prefer to hire a professional for accurate calibration and installation.
What happens if my tire sensor breaks?
If your tire sensor breaks, the TPMS light will illuminate on your dashboard, signaling a potential issue with tire pressure. You should replace the sensor to ensure accurate monitoring and prevent further problems.
