The most common reasons a 2021 Ford EcoSport 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 EcoSport 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 EcoSport?

To effectively diagnose the tire pressure warning light issue in your 2021 Ford EcoSport, begin with a thorough check of the tire pressure in all four tires using a reliable tire pressure gauge. This initial step is crucial as it ensures that the tire pressure aligns with the recommended levels found in your vehicle's manual. Next, inspect each tire for visible damage, such as punctures, cuts, or bulges, and look for any foreign objects that may be causing a leak. If the tire pressure is correct and no damage is evident, consider resetting the tire pressure monitoring system (TPMS) as outlined in your vehicle's manual, as this can sometimes resolve false warnings. Should the warning light persist despite these efforts, it may be time to consult a mechanic for a professional diagnosis, as the issue could stem from faulty sensors that require replacement. By following this diagnostic approach, you can systematically address the tire pressure warning light issue and ensure your vehicle remains safe and roadworthy.

What could be causing the tire pressure warning light to stay on in a 2021 Ford EcoSport?

When the tire pressure warning light stays on in a 2021 Ford EcoSport, it can signal several underlying issues that DIYers should investigate. The most common reason is low tire pressure, which can be easily checked with a tire pressure gauge. Ensuring that all tires are inflated to the recommended levels is vital for safe driving and optimal vehicle performance. If the tire pressure is correct, the problem may stem from a faulty tire pressure sensor that could require replacement if it fails to provide accurate readings. Additionally, sensor calibration issues might arise, which typically necessitate professional recalibration to ensure proper functionality. Electrical faults within the tire pressure monitoring system can also cause the warning light to remain illuminated, indicating the need for a diagnostic check to identify the specific issue. Furthermore, extreme temperature changes can affect tire pressure readings, so it's crucial to check the pressure when the tires are cold for the most accurate results. If these troubleshooting steps do not resolve the warning light issue, seeking assistance from a qualified mechanic is recommended to ensure the vehicle's safety and reliability.

What should I do if the tire pressure warning light on my 2021 Ford EcoSport stays on?

When the tire pressure warning light on your 2021 Ford EcoSport remains illuminated, it is crucial to act promptly to avoid potential safety hazards and costly repairs. Ignoring this warning can lead to decreased fuel efficiency, uneven tire wear, and even tire blowouts, which pose serious risks while driving. Start by checking the tire pressure in all four tires, including the spare, using a reliable tire pressure gauge. Ensure that each tire is inflated to the recommended levels found in your vehicle's manual or on the sticker inside the driver's side door jamb. If you discover any underinflated tires, inflate them accordingly to maintain optimal performance. Additionally, inspect your tires for any visible damage, such as punctures or bulges, as these can compromise safety and require immediate attention. After making necessary adjustments, you may need to reset the tire pressure monitoring system (TPMS) to clear the warning light; refer to your owner's manual for specific instructions. If the light persists despite your efforts, it is advisable to consult a qualified mechanic or visit a Ford dealership to prevent further complications. Taking these steps not only ensures your safety but also enhances the longevity of your tires and vehicle.
