Tire Pressure Sensor Not Working: Causes and Solutions

“Driving long distances with low tire pressure is very dangerous. Luckily, the tire pressure sensor alerted me in time!” – Mr. Ba, a long-haul truck driver on the Hanoi – Hai Phong route, shared. Indeed, the tire pressure monitoring system (TPMS) is a valuable tool, helping drivers feel secure on every journey. However, sometimes this “friend” malfunctions and fails to receive signals, leaving many drivers confused. So, what are the causes and how to fix a tire pressure sensor not working? Let’s find out with xetaihanoi.edu.vn!

1. What is a Tire Pressure Sensor? The Importance of Tire Pressure Monitoring

A tire pressure monitoring system (TPMS) is a small electronic system embedded in tires to monitor the tire pressure of trucks, dump trucks, tractors, etc. in real-time. This system sends a warning to the driver when the tire pressure drops below the standard level, helping drivers take timely action and avoid potential accidents.

According to Mr. Nguyen Van A, an automotive technical expert at Minh Phu Truck Garage (Cau Giay, Hanoi), regularly monitoring tire pressure offers many practical benefits such as:

• Improved braking performance and handling: Proper tire pressure ensures better road grip, shortens braking distance, especially in slippery conditions.
• Fuel efficiency: Underinflated tires increase friction with the road surface, forcing the engine to work harder, leading to higher fuel consumption.
• Extended tire lifespan: Properly inflated tires distribute the vehicle’s weight evenly, promoting even tire wear and extending tire life.
• Safer operation: Underinflated tires can cause blowouts, especially at high speeds or when carrying heavy loads. Monitoring tire pressure helps prevent this, ensuring the safety of people and vehicles.

2. Why is My Tire Pressure Sensor Not Working?

There are many reasons why a tire pressure sensor might not be working. The most common include:

2.1. Sensor Battery Failure

Tire pressure sensors are battery-powered, typically lasting 5-7 years. When the battery is weak or dead, the sensor cannot send signals to the receiver on the vehicle.

2.2. Sensor Damage

Tire pressure sensors can be damaged by strong impacts, water submersion, or poor sensor quality.

2.3. Faulty or Incorrectly Installed Valve Stem

The valve stem connects the sensor to the tire. A damaged, rusted, or improperly installed valve can prevent the sensor from transmitting signals.

2.4. Faulty Receiver Unit in the Vehicle

The receiver unit in the vehicle receives signals from the sensor and displays them on the dashboard. If this unit malfunctions, the sensor will not function.

2.5. Interference from Other Electronic Devices

Signals from phones, Bluetooth devices, dashcams, etc., can interfere with the tire pressure sensor signal.

4. Frequently Asked Questions about Tire Pressure Sensor Malfunctions

Question 1: How do I know if my tire pressure sensor is faulty?

Answer: When a tire pressure sensor malfunctions, the TPMS warning light on the dashboard will illuminate. You can also identify it through signs like:

• Inaccurate tire pressure readings on the display.
• No low-pressure warning when tires are underinflated.
• Sensor not receiving signals after battery replacement.

Question 2: Where can I get a tire pressure sensor replaced reliably in Hanoi?

Answer: You can purchase and replace tire pressure sensors at reputable garages such as:

• Minh Phu Truck Garage – Cau Giay
• Bridgestone Tire Service Center – Hoang Mai
• Thanh Cong Auto Parts Store – Hai Ba Trung

You can also consult friends, relatives, or seek information on truck and automotive forums and groups.

5. How to Fix a Tire Pressure Sensor Not Working

Depending on the cause of the problem, you can apply the following solutions:

• Check and replace the sensor battery: If the battery is weak, replace it with a new one.
• Check and replace the valve stem: Inspect the valve stem for damage or rust. Replace it if necessary.
• Take your vehicle to a garage for inspection: If the above steps don’t resolve the issue, take your vehicle to a reputable garage for diagnosis and repair.

6. Precautions When Using Tire Pressure Sensors

• Install the tire pressure sensors correctly and according to specifications.
• Check and replace sensor batteries periodically (every 2-3 years).
• Protect the sensors when patching or changing tires.
• Choose genuine, high-quality tire pressure sensors that are compatible with your vehicle model.
