The most common reasons a 2021 Ford Bronco Sport 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 2021 Ford Bronco Sport 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 2021 Ford Bronco Sport?

To effectively diagnose the tire pressure warning light issue in your 2021 Ford Bronco Sport, begin with a straightforward approach by checking the tire pressure in all four tires using a reliable tire pressure gauge. Ensure that the readings align with the recommended PSI found in your owner's manual or on the driver's side door jamb sticker. Next, inspect each tire for any visible damage, such as punctures or bulges, which could indicate a loss of pressure. If you find that the tire pressure is low, adjust it by inflating or deflating the tires to the correct levels. After making these adjustments, it may be necessary to reset the tire pressure monitoring system (TPMS); refer to your owner's manual for specific instructions on how to do this. Additionally, don't overlook the spare tire, as it can also trigger the warning light if its pressure is insufficient. If the warning light remains illuminated despite these checks, it may signal a more complex issue with the TPMS sensors or system, at which point consulting a mechanic or dealership for further diagnosis is advisable. By following this diagnostic approach, you can systematically address the tire pressure warning light issue and ensure your vehicle's safety and performance.

What could be causing the tire pressure warning light to remain on in a 2021 Ford Bronco Sport?

When the tire pressure warning light stays illuminated in a 2021 Ford Bronco Sport, it signals potential issues that DIYers can troubleshoot effectively. Start by checking the tire pressure in all four tires, as low pressure is the most frequent cause of the warning light. Inflate any under-inflated tires to the recommended levels, which are usually indicated on a sticker inside the driver's door. If the tire pressure is adequate, inspect the tire pressure sensors for faults; a malfunctioning sensor may need replacement. Additionally, recalibrating the sensors can often resolve inaccuracies in pressure readings, and this can typically be done by following the instructions in the vehicle's manual. If the warning light persists, investigate possible electrical faults within the tire pressure monitoring system, which may require specialized diagnostic tools. Lastly, ensure that the sensors are clean and unobstructed, as external debris can interfere with their operation. By addressing these issues promptly, you can ensure the safety and optimal performance of your Ford Bronco Sport.

How urgent is it to address the tire pressure warning light on my 2021 Ford Bronco Sport?

Addressing the tire pressure warning light on your 2021 Ford Bronco Sport is not just a matter of convenience; it is a critical safety concern that requires immediate attention. Ignoring this warning can lead to serious consequences, including compromised vehicle handling and stability, which can significantly increase the risk of accidents. Underinflated tires can also result in decreased fuel efficiency, costing you more at the pump, and can accelerate tire wear, leading to costly replacements. Moreover, driving on tires that are not properly inflated raises the likelihood of a blowout, particularly at high speeds, posing a severe danger to you and other road users. Additionally, maintaining the correct tire pressure is essential for optimal traction, especially in challenging weather conditions, ensuring that your vehicle performs reliably when you need it most. Therefore, it is imperative to take prompt action when the tire pressure warning light illuminates, safeguarding your safety and enhancing the longevity of your tires.
