The TPMS (Tire Pressure Monitoring System) is designed to notify you when a tire’s pressure is too low and may result in hazardous driving situations. If the indicator is on, your tires may not be properly inflated, which might result in premature tire wear and even tire failure. It’s critical to comprehend the value of appropriate tire inflation and how TPMS can prevent a potentially hazardous situation.
Both excessive and inadequate tire inflation can result in early tread deterioration and potential tire failure. Increased traction, early wear, and an inability to withstand impact from the road can all be effects of overinflation. The middle of the tread on tires with excessive air pressure may prematurely wear out. Underinflation, on the other hand, results in slow tire reaction, lower fuel economy, excessive heat buildup, and tire overload. The shoulders or tread edges of a tire that is underinflated will prematurely wear out on both sides.
Finding the TPMS indicator on your dashboard is straightforward if this is your first time hearing about tire pressure sensors. It is a light that has a horseshoe form with an exclamation point in the middle.

My 2010 Sonata has TWO different graphical warning symbols for low tire pressure: one is a cross-section of a tire with an exclamation point in it, and the other is a text warning that reads “TPMS” that illuminates if communication between the wheel pressure sensor and the car is lost. Therefore, on mine, if the TPMS in text is illuminated, it may still be safe to drive even though the tire pressure may not be low. Just be sure to check the tires frequently, pay attention to how the car handles, and take it to a repair to have it serviced.
It implies that a sensor is malfunctioning. In order to examine your tires, you will have to do it the old-fashioned way: by looking. till the sensor is fixed. My Sonata is a 2008 model.
The issue is the same for us. Four sensors total have been replaced thus far, and a week after the final sensor was changed, the light turned back on. Considering how inexpensive you may get the part, all work has been done at a Hyundai dealer for a significant amount.
What does the Hyundai Elantra’s TPMs light mean?
Your Hyundai Elantra’s TPMS light turning on indicates that one of the tires has low pressure. Tire pressure monitoring system is referred to as TPMS. When this light illuminates, you should inspect each tire to make sure there are no noticeable holes, screws, or nails in them. Then, as instructed on the sticker on the driver’s door jamb, you should inflate the tires to the recommended PSI. Pressing and holding the TPMS button on the dash will reset the system and turn off the light after all the tires have been inflated. To avoid uneven tire wear, it’s crucial to maintain your tires inflated.
The tire pressure monitoring system (TPMS) light on a Hyundai Elantra indicates that one of the tires has low air pressure.
TPMS for Hyundai
Hyundai vehicles are equipped with TPMS, or tire pressure monitoring systems, which may detect low tire pressure in any of the car’s four tires and issue an alert. According to the table below, a TPMS from one of two manufacturers is installed as a component of the valve assembly in every Hyundai vehicle.
According to the table below, a TPMS from one of two manufacturers is installed as a component of the valve assembly in every Hyundai vehicle. The tire pressure monitor ECU/receiver receives the data from the sensor, which detects the pressure and temperature inside the tire, together with the TPMS’s distinctive ID.
If the TPMS ID is stored with the ECU, the placard pressure is checked with it, and if there is a pressure difference, a warning light is illuminated on the dash-mounted display.
How do you reset the Hyundai TPMS?
Once the TPMS light has flashed three times, let go of the tire pressure monitor reset button. Start the engine and give the sensor 20 minutes to refresh. Under the steering wheel is typically where you’ll find the TPMS reset button.
How is the TPMS fixed?
When the tire pressure light blinks three times, release pressure on the TPMS reset button. For the sensors to reset, start the car and let it run for 20 minutes. The button to reset the tire pressure monitor is under the steering wheel.
Can you operate a vehicle with a TPMS issue?
Depending on how many kilometers a vehicle is driven, the service life can change.
Tire pressure sensors that have reached their end of the line are to blame for the majority of TPMS failures. The lifespan of the batteries in tire pressure sensors is normally between 5 and 7 years. Depending on how many kilometers a vehicle is driven, the service life can change. Additionally, rust on or inside the valve stem might cause tire pressure sensors to malfunction. This has been a significant issue with several brands, most notably Toyota, and has led to valve stems snapping or coming off, which causes a tire to go flat suddenly—exactly the type of thing that TPMS sensors were meant to prevent!
Sensors with metal stems are more susceptible to corrosion than those with rubber stems. A TPMS system can also malfunction due to TPMS module, keyless entry, and wiring issues, however these issues are considerably less frequent. When a tire pressure sensor malfunctions, the TPMS system should recognize it and illuminate or flash the TPMS warning light.
Unfortunately, a lot of drivers are unaware of what the TPMS warning light looks like or indicates, thus it can be disregarded. As long as the tires are keeping normal air pressure, the car is still safe to drive, but without the TPMS system, there will be no low tire pressure alert if a tire begins to go flat.
TPMS sensors should typically be replaced when the vehicle needs a new set of tires, which is usually after 5 to 7 years or 60,000 to 80,000 miles. The TPMS sensors might still be working when the first set of tires is changed, but it’s unlikely that the batteries will still have enough life in them to power a second set of tires under normal driving circumstances. The types and designs of TPMS sensors vary, and some original equipment sensors can be very pricey. A “universal” replacement sensor that may be configured to function in a wide range of applications is currently offered by the majority of aftermarket sensor suppliers. These sensors’ electronics include a variety of protocols, allowing them to function in a wide range of applications. While some sensors operate at a 125 KHz frequency, others operate at 309 MHz, 433 MHz, or other frequencies. Although they will need a TPMS service tool to program the sensors for the application and to reset the system, professional installer customers will find it easier to install a universal sensor and your inventory requirements will be reduced.
No. The actual architecture of the sensor shouldn’t matter as long as it produces the same signal frequency and broadcasts the same information as the original. While universal TPMS sensors could be different from the original design, direct replacement TPMS sensors are identical to the original (same fit and function). A rubber valve stem sensor can be used to replace large TPMS sensors that are sometimes positioned in the drop center of wheels with a steel band.
Can I change my own TPMS?
The Tire Pressure Monitoring System, which notifies you when a tire is dangerously low on air, typically uses TPMS sensors embedded in the tires to detect low tire pressure. The majority of TPMS sensors use internal batteries that cannot be changed to power them.
The lithium ion batteries in a TPMS sensor have a lifespan of 5 to 10 years. The duration of the TPMS sensor batteries is difficult to predict because it depends on how many radio frequency broadcasts the sensors send out. The amount of driving you perform over time and the conditions you drive in will affect the sensor battery life. The TPMS battery life is less affected by cold conditions than by warmer ones. When compared to continuous pace, stop-and-go traffic has a greater effect on TPMS battery life. This is due to the fact that sensors send out more radio frequency broadcasts as a vehicle changes its speed.
The system will issue a malfunction warning when a TPMS sensor’s battery runs out, which will be visible as a blinking TPMS light on your dashboard. After 60 to 90 seconds, the light may either continue to flash or turn solid. Be a repair appointment as soon as you can if you receive this warning, but also check the tire pressure in each tire right away to make sure you have safe inflation all around.
You can change each individual TPMS sensor separately if one of them malfunctions and needs to be replaced. The other sensors, on the other hand, are probably on the verge of failing as well if the failure was brought on by a dead sensor battery. You might wish to proactively replace all the sensors so you have brand-new sensor batteries all around when you take into account the time and hassle of taking your car off for a sensor replacement.
