The most common reasons a 2017 Lexus NX200t tire pressure warning light stays on are a leaking tire, a wheel that no longer holds air, or a faulty tire pressure monitoring system.
  • Tire Leaking Air: A puncture, valve stem issue, or rim damage can cause a tire to leak air, leading to loss of pressure.
  • Wheel Leaking Air: A puncture or damage to the tire or rim can cause air to leak, resulting in a loss of tire pressure.
  • Tire Pressure Monitoring System: A malfunctioning tire pressure monitoring system can be caused by faulty sensors or a dead battery in the sensor units.
Proper diagnosis will determine the exact cause of your symptom, saving you money on unnecessary repairs. The diagnostic experts at RepairPal Certified shops have the right tools and experience to solve any symptom.

How much does it cost to fix a 2017 Lexus NX200t tire pressure warning light stays on?

Common Repairs

The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.

When a tire pressure monitoring sensor fails, the tire pressure monitoring system control module will recognize a loss in communication and turn on the warning lamp which indicates the failure. This is most often the case. However, the tire pressure monitoring sensor may also fail by reporting incorrect tire pressures. This could cause a flat tire to go unrecognized, or a properly inflated tire to signal a low or high tire pressure warning.

When a relearn is needed, for any reason, the TPMS warning light will illuminate, and many vehicles will display a message relating to the TPMS system being inoperative or loosing communication. It is important to keep a watchful eye on tire pressures when this system is having issues because there is no warning available for underinflation or overinflation of the tires.

Wheels offer very few symptoms, but these symptoms should never be ignored. Visible cracks on the wheels may appear, especially after hitting a large bump, Most often, this will also be accompanied by loss of air from the tire on that wheel. Also, vibration in the steering wheel is very common when the tire is out of balance, and improper wheel nuts or bolts can cause creaking and popping noises to develop. Again, there are very few symptoms, but they should not be ignored.

The only symptoms requiring diagnosis for the tire pressure monitoring system warning lamp is if the warning lamp has illuminated while the tires have correct air pressure, or if the air pressure for the tires is out of specification and the warning lamp is off. This is because the overwhelming majority of cases where the TPMS lamp illuminates is due to the change in ambient temperature.

What steps should I take to diagnose the tire pressure warning light issue in my 2017 Lexus NX200t?

To effectively diagnose the tire pressure warning light issue in your 2017 Lexus NX200t, begin with a thorough check of the tire pressure in all four tires using a reliable tire pressure gauge. Ensure that the readings align with the recommended levels found in your vehicle's manual, as incorrect pressure is a common cause for the warning light. Next, inspect the tires for any visible damage, such as punctures, cuts, or bulges, which could indicate a more serious problem. If the tires appear to be in good condition, attempt to reset the tire pressure monitoring system, as this can sometimes clear false warnings. Additionally, examine the valve stems for any signs of damage or leaks that might trigger the warning light. If, after these steps, the warning light remains illuminated, it is advisable to consult a mechanic or dealership for a comprehensive diagnosis, as they can identify more complex issues that may not be immediately apparent. By following this diagnostic approach, you can systematically address the problem and ensure your vehicle's safety on the road.

What are the common causes for the tire pressure warning light to remain on in a 2017 Lexus NX200t?

When the tire pressure warning light remains illuminated in a 2017 Lexus NX200t, it can signal several common issues that DIY enthusiasts can troubleshoot. The most frequent cause is low tire pressure; therefore, it's essential to check each tire and inflate them to the recommended levels. If the pressure is adequate, the next step is to examine the tire pressure sensor, as it may be faulty and unable to provide accurate readings. Inspecting the sensor for any visible damage or wear can help identify the problem. Additionally, consider that the sensor batteries might need replacement, as they have a finite lifespan and can lead to persistent warning lights when they are depleted. Calibration of the sensors is another important aspect; they may require adjustment to ensure they are functioning correctly. If these DIY solutions do not resolve the issue, it may indicate a more complex malfunction within the tire pressure monitoring system, which would require professional diagnosis. Addressing these concerns promptly is vital for ensuring the safety and performance of your vehicle.

What immediate steps should be taken to address the tire pressure warning light that remains on in a 2017 Lexus NX200t?

When the tire pressure warning light remains illuminated in your 2017 Lexus NX200t, it is crucial to act promptly to ensure your safety and prevent further damage to your vehicle. Ignoring this warning can lead to unsafe driving conditions, such as reduced traction and increased tire wear, which may ultimately result in a blowout or costly repairs. Start by checking the tire pressure in all four tires with a reliable gauge, ensuring they are inflated to the manufacturer's recommended levels. If you find any tires underinflated, use an air compressor to bring them up to the correct pressure. Additionally, inspect each tire for visible damage, such as punctures or bulges, as these can compromise your vehicle's safety. After making necessary adjustments, you may need to reset the tire pressure monitoring system, which can typically be done through your vehicle's onboard menu. If the warning light persists despite these efforts, it is essential to consult a qualified mechanic to diagnose any underlying issues with the monitoring system. Taking these immediate steps not only enhances your driving safety but also helps maintain the longevity and performance of your Lexus NX200t.
