Common Causes of TPMS Malfunction
There are several reasons why your TPMS may be malfunctioning, including problems with the tire pressure sensors themselves, the activation of the tire pressure warning light, and the need for a TPMS reset. Understanding these common causes can help you troubleshoot and resolve TPMS issues effectively.
One of the main causes of TPMS malfunction is problems with the tire pressure sensors. These sensors are responsible for transmitting data about the tire pressure to the TPMS system. Over time, the batteries of these sensors can become discharged, leading to a loss of transmission. Additionally, the sensors can become damaged due to tire-to-curb impacts or improper tire mounting/dismounting procedures. In such cases, the affected sensor will need to be replaced.
“A Tire Pressure Sensor Fault can also occur when there is a loss of tire pressure. Some vehicles may display a TPMS fault when there is low tire pressure, confusing it with an actual sensor issue. It is important to manually check the inflation of each tire with a gauge to determine if there is a low tire pressure situation. Driving on underinflated tires can be dangerous and can cause severe tire damage.”
Another common cause of TPMS malfunction is the activation of the tire pressure warning light. This warning light indicates that one or more tires have low pressure. Sometimes, the light may come on when the tire pressure is too high or when there is a fault in the system. In either case, it is essential to check the pressure of all tires manually using a gauge and adjust them to the manufacturer’s recommended specifications.
In certain cases, a TPMS reset may be required to resolve the malfunction. This is often necessary when there have been changes to the wheels or tires, such as mounting new tires or swapping between seasonal wheels. These changes can affect the pressure requirements for the TPMS system, and a reset is needed to ensure accurate monitoring. Consult your vehicle’s owner’s manual or seek professional assistance to perform a TPMS reset.
|Causes of TPMS Malfunction|
|Problems with tire pressure sensors||Discharged batteries or damage|
|Tire pressure warning light activation||Low or high tire pressure, system fault|
|TPMS reset||Changes in wheels or tires|
Understanding the common causes of TPMS malfunctions is crucial for effective troubleshooting. Whether it’s problems with the tire pressure sensors themselves, the activation of the tire pressure warning light, or the need for a TPMS reset, addressing these issues promptly can help ensure the accurate monitoring of tire pressure and prevent potential safety hazards. Remember to manually check tire pressure regularly and follow proper maintenance procedures to keep your TPMS functioning optimally.
Troubleshooting TPMS Issues
If you’re experiencing TPMS issues, understanding what the low tire pressure indicator means and implementing proper maintenance can help you identify and resolve the problem. The TPMS (Tire Pressure Monitoring System) is designed to alert you when tire pressure is too low, which can lead to unsafe driving conditions. Here are some essential tips for troubleshooting TPMS issues:
- Check the low tire pressure indicator: The TPMS indicator on your dashboard is a horseshoe-shaped light with an exclamation point in the center. When this light illuminates, it means your tires could be underinflated. Manually check your tire pressures with a gauge and add air until the pressures reach the vehicle manufacturer’s specification.
- Maintain proper tire pressure: Both overinflation and underinflation can cause tire wear and possible tire failure. Overinflated tires will show premature wear in the center of the tread, while underinflated tires will show premature wear on both sides of the tread edges or “shoulders.” Regularly check and maintain proper tire pressure to avoid TPMS issues.
- Address TPMS warning lights: When the TPMS warning light comes on and stays on, it indicates that at least one of your tires is at a low pressure level. Use a gauge to check the pressure of all the tires and determine the cause of pressure loss. If the TPMS light flashes and then stays on, it means the TPMS isn’t functioning properly and requires inspection and repair at an automotive service center.
Remember, while TPMS can help alert you when pressure is low, it shouldn’t replace regular tire pressure checks. The TPMS warning light may be set to illuminate below the tire pressure needed to carry the load in the vehicle, and the system may not be able to accurately determine if a tire is too low if other tires are losing pressure at the same rate. Therefore, it’s important to check tire pressure once a month and before long trips or when carrying extra load.
|TPMS warning light on and stays on||Low tire pressure||Manually check tire pressures with a gauge and add air as needed|
|TPMS warning light flashes and then stays on||TPMS malfunction||Take the vehicle to an automotive service center for inspection and repair|
By understanding and addressing TPMS issues promptly, you can ensure the safety and performance of your vehicle’s tires. Regular tire pressure checks and proper maintenance are key to preventing potential problems and ensuring optimal tire performance.
Dealing with TPMS Warning Lights
When the TPMS warning light comes on, it’s important to know how to react depending on whether it illuminates while driving, goes on and off intermittently, or flashes before staying on. Understanding the different scenarios can help you take appropriate action and ensure the safety of your vehicle and tires.
TPMS Light Illuminates While Driving
If the TPMS light comes on and stays on while you’re driving, it indicates that at least one tire has low pressure. The first step is to safely pull over and manually check the pressure of all your tires using a gauge. Add air to any tire that is below the recommended pressure specified by your vehicle manufacturer. Once you’ve inflated the tires, you should continue driving cautiously and monitor the TPMS to ensure the light stays off.
TPMS Light Goes On and Off Intermittently
If the TPMS light turns on and then goes off intermittently, it’s likely due to fluctuating temperatures. Temperature changes can cause tire pressure to slightly decrease or increase, triggering the TPMS light. To address this, check the pressure of all your tires with a gauge and add air to any tire that is low. It’s important to keep in mind that proper tire pressure should be maintained for optimal performance.
TPMS Light Flashes and Then Stays On
If the TPMS light flashes for about 60 to 90 seconds when you start your car and then remains illuminated, it indicates a malfunction in the TPMS system. In this case, it’s recommended to take your vehicle to an automotive service center for inspection and repair. While awaiting repairs, continue to check the air pressure of all your tires with a gauge and add air as needed to ensure they are properly inflated.
Remember, the TPMS is a valuable tool for monitoring tire pressure, but it shouldn’t replace regular tire pressure checks. Even with a functioning TPMS, it’s essential to manually check your tire pressure once a month and before long trips or when carrying extra load. Regular maintenance and proper tire inflation contribute to safe and efficient driving.
TPMS Sensors and Their Location
TPMS sensors are installed inside each tire, usually attached to the valve stem where you fill the tire with air. Each tire has its own sensor, so if you’re experiencing a TPMS warning light, it could be due to a fault in any of the sensors. It’s important to have a qualified technician diagnose and replace the faulty sensor as needed.
