The most common reasons a 2019 Ford Fiesta 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 2019 Ford Fiesta 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 2019 Ford Fiesta?

To effectively diagnose the tire pressure warning light issue in your 2019 Ford Fiesta, begin with a straightforward approach that prioritizes simple solutions before delving into more complex diagnostics. Start by checking the tire pressure in all four tires using a reliable tire pressure gauge, ensuring they are inflated to the levels recommended in your vehicle's manual. This initial step is crucial, as improper tire pressure is a common cause of the warning light activation. Next, inspect each tire for visible damage, such as punctures or bulges, which could indicate a more serious problem. If the tires are in good condition and properly inflated, consider resetting the tire pressure monitoring system (TPMS) as outlined in your vehicle's manual, as this can sometimes resolve the issue. After making any necessary adjustments, take your Fiesta for a short drive; the TPMS may need to recalibrate to turn off the warning light. If the light remains illuminated despite these efforts, it may be time to consult a mechanic or dealership for a thorough inspection of the TPMS, as persistent issues could signal sensor malfunctions or other underlying problems. By following this diagnostic approach, you can efficiently address the tire pressure warning light and ensure your vehicle's safety on the road.

What could be causing the tire pressure warning light to remain on in a 2019 Ford Fiesta?

When the tire pressure warning light stays illuminated in a 2019 Ford Fiesta, it can be a source of concern for drivers. The most common issue is low tire pressure, which can easily be checked and adjusted to the manufacturer's recommended levels. If the tire pressure is adequate and the light remains on, the next step is to consider the possibility of a faulty tire pressure sensor, which may need replacement. Additionally, some sensors are equipped with batteries that can deplete over time, leading to persistent warning lights. If these components are functioning correctly, the tire pressure monitoring system might require recalibration, a task that can often be completed by following the instructions in the vehicle's manual. In rare cases, underlying electrical issues could be the cause, necessitating a professional diagnostic check to identify and resolve any complex problems. By methodically addressing these potential causes, you can effectively troubleshoot and resolve the tire pressure warning light issue in your Ford Fiesta.

How urgent is it to address the tire pressure warning light that stays on in a 2019 Ford Fiesta?

Addressing the tire pressure warning light that remains illuminated in a 2019 Ford Fiesta is an urgent matter that should not be overlooked. Ignoring this warning can lead to serious safety concerns, as improper tire pressure significantly affects vehicle handling and braking, increasing the likelihood of accidents or tire blowouts. Additionally, neglecting to check and adjust tire pressure can result in uneven tire wear, which not only shortens the lifespan of your tires but also poses a risk of sudden tire failure while driving. Furthermore, maintaining the correct tire pressure is essential for optimal fuel efficiency; under-inflated tires can lead to increased fuel consumption, ultimately costing you more at the pump. The Tire Pressure Monitoring System (TPMS) is designed to alert you to these issues, and failing to address the warning can compromise the system's effectiveness. Therefore, it is crucial to check your tire pressure regularly, inflate your tires to the recommended levels, and consult a qualified mechanic for any underlying issues to ensure your safety and the longevity of your vehicle.
