The most common reasons a Lincoln MKT 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 Lincoln MKT 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.

Troubleshooting Tire Pressure Warning Light in a Lincoln MKT

When faced with a tire pressure warning light in your Lincoln MKT, the first step is to check the air pressure in all tires, as low pressure is the most common trigger for this alert. Use a reliable tire gauge to ensure accuracy, and adjust the pressure to the specifications found on the vehicle's certification label, typically located on the driver's door. If the light remains illuminated after correcting the tire pressures, consider the possibility of a depleted battery in one of the tire pressure sensors. In this case, replacing the battery may resolve the issue. If the problem persists, inspect the TPMS receiver module for any malfunctions, as this component is crucial for relaying tire pressure information to the vehicle's system. Lastly, if you suspect damage to a pressure sensor, it may need to be replaced. Once any necessary adjustments or repairs are made, utilize a TPMS Relearn Tool to reset the system, ensuring that the warning light is turned off and that your vehicle is accurately monitoring tire pressure moving forward.

What to Do When the Tire Pressure Warning Light Stays On in a Lincoln MKT?

When the tire pressure warning light remains on in your Lincoln MKT, it can be indicative of several common problems that may require your attention. One frequent issue is simply low tire pressure, which can occur due to temperature changes or slow leaks. It's essential to regularly check the air pressure in all tires, including the spare, to ensure they are inflated to the manufacturer's recommended levels. Additionally, visible damage to the tires, such as punctures or sidewall bulges, can trigger the warning light, necessitating a thorough inspection. If the tire pressure is adequate and no damage is found, the problem may lie within the TPMS itself. This could involve a malfunctioning tire pressure sensor, which may need replacement, or a depleted battery in the sensor. In some cases, the TPMS receiver module may also fail, leading to persistent warning lights. If you've checked the tires and reset the system according to your vehicle's manual but the light remains on, it’s advisable to consult a qualified technician for further diagnosis. Understanding these common issues can empower you to take the right steps in maintaining your vehicle's safety and performance.

Why is the Tire Pressure Warning Light Staying On in a Lincoln MKT?

When the tire pressure warning light remains illuminated in your Lincoln MKT, it is crucial to address the issue without delay. Ignoring this warning can lead to unsafe driving conditions, as low tire pressure can significantly affect vehicle handling and increase the risk of tire blowouts. Additionally, a malfunctioning TPMS sensor or a depleted battery in a pressure sensor can lead to further complications, potentially resulting in costly repairs. If you notice the light staying on despite checking and inflating your tires to the recommended pressure, it may indicate a deeper issue, such as a damaged sensor or a malfunctioning TPMS receiver module. For DIY enthusiasts, it is advisable to first ensure that all tires are properly inflated and then consider using a scanner to reset the TPMS system if necessary. Addressing these issues promptly not only enhances your safety on the road but also helps maintain the overall health of your vehicle, preventing more significant problems down the line.
