Why Is Hyundai Elantra Tire Pressure Sensor Light On?
- Temperature change can affect tire pressure.
- Over-inflated or under-inflated tires.
- Damaged or worn-out tires.
- Faulty tire pressure sensor.
- Low tread depth on tires.
- Leaking air valves.
- Incorrectly calibrated tire pressure monitoring system (TPMS).
- Driving with a heavy load or towing.
- Changes in altitude.
- Using different sized tires than recommended by the manufacturer.
Temperature change can affect tire pressure
One of the most common reasons for the tire pressure light to come on is temperature changes. As temperatures rise and fall, so does the air pressure inside your tires.
This can cause fluctuations in the readings of your TPMS (tire pressure monitoring system), leading to a warning light.
Reasons: So why does temperature affect tire pressure? This is due to the ideal gas law, which states that when temperature increases, so does the volume and pressure of a gas.
In simpler terms, as the air inside your tires heats up, it expands and creates more pressure. This can lead to over-inflated tires and trigger the tire pressure light.
It’s important to note that this issue is not limited to just hot weather. Cold temperatures can also cause a decrease in tire pressure, as the air becomes denser and contracts. This can result in under-inflated tires and trigger the tire pressure light as well.
Solutions: To prevent temperature changes from affecting your tire pressure, it’s important to regularly check and adjust your tire pressure according to the recommended levels for your vehicle. This information can usually be found in your owner’s manual or on a sticker located inside the driver’s door jamb.
Additionally, investing in a quality TPMS can help you monitor and maintain proper tire pressure. Some newer models even have a feature that alerts you when the tire pressure is outside of the recommended range due to temperature changes.
Over-inflated or under-inflated tires
While temperature changes are a common cause of the tire pressure light coming on, it’s important to also check for other issues such as over-inflated or under-inflated tires.
Over-inflated tires have too much air pressure, causing the tire to become harder and more prone to wear in the centre. This can also lead to a bumpy ride and decreased traction.
On the other hand, under-inflated tires have too little air pressure, causing the tire to become softer and more prone to wear on the edges. This can also result in decreased fuel efficiency and increase the risk of a tire blowout.
Solutions: To avoid these issues, regularly check your tire pressure using a reliable tire gauge and adjust accordingly. It’s also important to note that over-inflated or under-inflated tires can be caused by a leak or damage to the tire itself, so it’s always best to have a professional mechanic inspect and repair any issues.
Damaged or worn-out tires
In some cases, the tire pressure light may come on due to a damaged or worn-out tire.
Reasons: This can be caused by factors such as driving over rough terrain, hitting potholes, or simply from normal wear and tear.
Other reasons for damaged or worn-out tires may include improper tire maintenance, driving with excessive weight in the vehicle, or using mismatched tires.
Solutions: If you notice any cracks, bulges, or other signs of damage on your tires, it’s important to have them replaced as soon as possible. Driving on damaged tires can not only affect your vehicle’s performance but also pose a safety hazard.
Faulty tire pressure sensor
In some cases, the tire pressure light may be triggered by a faulty sensor.
A tire pressure sensor is a device that monitors the air pressure inside your tires and sends this information to your vehicle’s computer.
This allows for real-time monitoring of tire pressure and alerts you when there is a significant change or decrease in pressure.
Reasons: One reason a tire pressure sensor may fail is due to a dead or low battery. If the battery in the sensor dies, it will no longer be able to transmit data to your vehicle’s computer, causing the tire pressure light to turn on.
Additionally, dirt and debris can build up around the sensor, affecting its accuracy and causing it to malfunction.
Solutions: If you suspect that your tire pressure sensor is malfunctioning, try resetting it first by following the instructions in your vehicle’s manual. If the light continues to come on, it’s best to have it checked by a professional mechanic for further diagnosis and potential replacement.
Low tread depth on tires
In addition to monitoring tire pressure, it’s also important to keep an eye on your tire tread depth.
Low tread can affect the performance and safety of your vehicle, especially in wet or slippery conditions. The recommended tread depth for most tires is between 4/32 inch and 6/32 inch.
Reasons: There are a few reasons why your tire tread depth may be low. One reason could be regular wear and tear over time, especially if you frequently drive on rough or uneven roads.
Another reason could be improper maintenance, such as not rotating your tires regularly to ensure even wear. Additionally, using the wrong type of tires for your driving habits can also contribute to low tread depth.
Solutions: There are a few ways to address low tread depth on tires. One solution is to regularly check and maintain the proper tire pressure, as this can help prevent uneven wear and tear.
Another solution is to rotate your tires every 6,000-8,000 miles to ensure even distribution of tread wear. You can also invest in high-quality tires that are specifically designed for your driving habits and the conditions you frequently encounter.
If your tire tread depth is significantly low, it may be time to replace your tires altogether. It’s important to prioritize safety and invest in new tires when necessary to ensure optimal performance of your vehicle.
Leaking air valves
Another common cause of the Tire Pressure Light on Hyundai Elantra is leaking air valves.
Leaking air valves refers to the valve stem, also known as the Schrader valve, found on each tire that helps you inflate or deflate your tires. This valve can become loose or damaged over time, causing air to leak out of the tire and resulting in low tire pressure.
Reasons: This can happen when the valve stem or core becomes damaged, allowing air to slowly leak out of the tire. This can also be caused by a faulty valve cap that is not sealing properly.
Solutions: If you suspect that leaking air valves are causing the Tire Pressure Light to turn on in your Hyundai Elantra, it’s important to address the issue promptly.
One solution is to tighten or replace the valve stem or core if they are damaged.
Another solution is to invest in high-quality valve caps that create a tight seal and prevent air from escaping. It’s also important to regularly check and replace valve caps if necessary.
Incorrectly calibrated tire pressure monitoring system (TPMS):
The Tire Pressure Light on Hyundai Elantra may also be triggered by an incorrectly calibrated TPMS. This system uses sensors to monitor the air pressure in each tire and alerts you when the pressure is too low.
However, if these sensors are not properly calibrated, they may provide inaccurate readings and trigger the Tire Pressure Light.
Reasons: This can happen if the sensors that measure tire pressure are not properly calibrated or if there is a malfunction in the system.
Solutions: If you suspect that your TPMS is not functioning correctly, it’s important to take your vehicle to a trusted mechanic or dealership for diagnosis and repair.
They will be able to recalibrate the sensors or replace any faulty components to ensure that your TPMS is accurately monitoring your tire pressure.
