What Happens If You Don’t Replace TPMS Sensors

In this blog, we’ll explore the consequences of what happens if you don’t replace TPMS sensors and the impact they can have on your vehicle’s safety and efficiency.

Modern vehicles are equipped with a range of sophisticated systems designed to enhance safety, and one such system is the Tire Pressure Monitoring System (TPMS). TPMS sensors play a crucial role in maintaining proper tire pressure, essential for safe driving and overall vehicle performance. 

Consequences of Neglecting TPMS Sensor Replacement

Timely replacement of TPMS sensors is essential for tire health and safe driving. If neglected, it can cause the following adversities for the car owners:

Reduced Fuel Efficiency

When tire pressure is not maintained, it increases the rolling resistance. That said, the engine has to work harder to move the vehicle, leading to decreased fuel efficiency and higher fuel consumption.

Considering the fuel prices around the world, one would not want their car to burn more fuel. That said, TPMS helps detect the low tire pressure earlier. 

Tire Wear and Damage

Improper tire pressure distribution can cause uneven wear on tires. Over time, this can lead to premature tire wear and reduce the lifespan of your tires. Replacing tires can be costly. Therefore, If you do not replace the TPMS sensors, it leads to unnecessary expenses, such as tire changes due to consistent low or high air pressure in tires.

Increased Risk of Accidents

Under-inflated tires affect the vehicle’s handling and braking performance. Reduced traction and longer braking distances can increase the risk of accidents, especially in emergencies or adverse weather conditions.

Blowouts and Safety Hazards

Driving with under-inflated tires puts extra stress on the tire sidewalls, increasing the likelihood of a blowout. Blowouts can lead to loss of control, causing accidents that could have severe consequences for both the driver and passengers.

Legal and Regulatory Consequences:

In some regions, there are legal requirements to have a functioning TPMS system. Driving with a malfunctioning TPMS system could result in fines or penalties, depending on local regulations.

Maintaining TPMS Sensors:

Regular maintenance and timely replacement of TPMS sensors are essential. These sensors have a limited lifespan due to exposure to the elements, temperature changes, and battery life. Replacing them when they are no longer functional is crucial to ensure accurate tire pressure monitoring.

Here are the steps to replace TPMS Sensors:

  • Refer to your vehicle’s manual for information on recommended replacement intervals and compatible TPMS sensor models.
  • Replacing TPMS sensors typically requires specialized tools and knowledge. It’s recommended to have a professional mechanic handle the replacement to ensure accurate calibration and proper installation.
  • After replacing the TPMS sensors, the system needs to be recalibrated to ensure accurate readings. This calibration process might involve resetting the system using the vehicle’s onboard computer or specialized equipment.

The TPMS system is a vital component of modern vehicle safety. Neglecting to replace TPMS sensors can lead to reduced fuel efficiency, increased tire wear, higher accident risks, and legal consequences. To maintain optimal safety, vehicle performance, and overall efficiency, it’s crucial to adhere to recommended TPMS sensor replacement intervals.
