The most common reasons a 2018 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 2018 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 on my 2018 Ford EcoSport?

To effectively diagnose the tire pressure warning light issue on your 2018 Ford EcoSport, begin with the simplest step: checking the tire pressure in all four tires using a reliable tire pressure gauge. This initial check is crucial, as maintaining the correct PSI is essential for safe driving and can often resolve the warning light issue. Next, inspect each tire for visible damage, such as punctures or bulges, which could indicate a more serious problem. If you find that the tire pressure is low, inflate the tires to the recommended level, or if they are overinflated, carefully release some air. After adjusting the pressure, it’s important to reset the tire pressure monitoring system (TPMS) to ensure it accurately reflects the new tire conditions. If the warning light remains illuminated, the issue may lie with a faulty tire pressure sensor, which would require professional inspection. Always refer to your owner’s manual for specific troubleshooting instructions tailored to your vehicle, as this can provide additional insights and guidance. By following these steps, you can systematically address the tire pressure warning light issue and ensure your Ford EcoSport is safe and road-ready.

What could cause the tire pressure warning light to stay on in a 2018 Ford EcoSport?

When the tire pressure warning light remains on in your 2018 Ford EcoSport, it can be frustrating, but understanding the common problems can help you troubleshoot effectively. One of the primary culprits is low tire pressure, which is easily checked with a tire pressure gauge. Ensure all tires are inflated to the manufacturer's recommended levels, as even a slight drop can trigger the warning light. If the pressure is adequate, consider the possibility of a faulty tire pressure sensor; these sensors can wear out over time and may need replacement. Additionally, sensor calibration issues can arise, particularly if tires have been recently changed or rotated, necessitating a recalibration to ensure accurate readings. Electrical faults within the tire pressure monitoring system can also lead to persistent warning lights, so a thorough inspection may be required to identify any underlying issues. Lastly, if all else fails, performing a system reset can sometimes resolve the problem, which can typically be done by following the vehicle's manual instructions. If the warning light continues to stay on after these checks, consulting a certified mechanic or Ford dealership is advisable for a comprehensive diagnosis.

How urgent is it to address the tire pressure warning light on a 2018 Ford EcoSport that stays on?

Addressing the tire pressure warning light on your 2018 Ford EcoSport is not just a matter of convenience; it is a critical safety concern that requires immediate attention. When this light remains illuminated, it signals that your tires may be underinflated, which can severely compromise your vehicle's handling and braking capabilities. This increases the likelihood of accidents, particularly in emergency situations where quick response is essential. Furthermore, driving on underinflated tires accelerates uneven wear, leading to premature tire replacement, which can be a costly endeavor. Additionally, low tire pressure negatively impacts fuel efficiency, resulting in higher fuel costs over time. Ignoring this warning can also lead to significant tire damage, including the risk of a blowout while driving. Therefore, it is crucial to check your tire pressure, inflate your tires to the recommended levels, and inspect for any leaks or punctures as soon as the warning light activates. Regular maintenance of your tire pressure not only enhances your vehicle's performance but also ensures your safety on the road.
