The most common reasons a Lincoln MKS 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 MKS 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 MKS

When troubleshooting the tire pressure warning light in your Lincoln MKS, it's essential to adopt a systematic diagnostic approach. Start by checking the tire pressure of all four tires, ensuring they are inflated to the manufacturer's recommended levels, which can be found on the Tire Label located on the driver's door. Once the tires are properly inflated, take the vehicle for a short drive at speeds exceeding 20 mph for at least two minutes; this allows the Tire Pressure Monitoring System (TPMS) to recalibrate. If the warning light remains illuminated, the next step is to reset the TPMS sensor, which may require a TPMS Relearn Tool. Should the light persist after these actions, it’s advisable to inspect the sensors for any faults or damage, as faulty components may need replacement. Always refer to your owner's manual for specific instructions related to your model year, as the reset process can vary. By following this methodical approach, you can effectively diagnose and resolve the tire pressure warning light issue in your Lincoln MKS.

Troubleshooting Tire Pressure Warning Light in Lincoln MKS

When troubleshooting the tire pressure warning light in your Lincoln MKS, it's important to recognize the common problems that could be triggering this alert. One of the primary culprits is tire leaks, which can cause a slow loss of air pressure, so checking both the tires and wheels for any signs of leaks is essential. Additionally, the Tire Pressure Monitoring System (TPMS) may not be functioning correctly, leading to false readings that activate the warning light. If you suspect an issue with the TPMS, utilizing an OBD-II scanner can assist in resetting the system and clearing any erroneous alerts. Once you've confirmed that your tires are inflated to the manufacturer's recommended pressure, driving the vehicle for a short distance allows the TPMS to recalibrate and accurately reflect the tire conditions. If you've recently changed tires or adjusted the pressure, resetting the TPMS sensor may also be necessary to turn off the warning light. By understanding these common issues and following the appropriate troubleshooting steps, you can effectively address the tire pressure warning light and ensure your Lincoln MKS remains safe and performs optimally on the road.

What Should You Do When the Tire Pressure Warning Light Stays On in a Lincoln MKS?

When the tire pressure warning light remains illuminated in your Lincoln MKS, it is crucial to address the situation without delay. Ignoring this warning can lead to serious safety risks, including reduced vehicle handling, increased tire wear, and even tire blowouts, which can result in accidents. Proper tire pressure is essential for optimal vehicle performance and fuel efficiency, so start by checking the pressure in all tires, including the spare. If you find any tires underinflated, inflate them to the recommended levels as specified in your owner's manual. Additionally, inspect each tire for signs of damage, such as punctures or bulges, which could compromise safety. After making necessary adjustments, resetting the tire pressure monitoring system is often required to clear the warning light. If the light persists despite your efforts, it’s wise to consult a professional, as there may be underlying issues with the TPMS that need expert attention. Taking these steps not only ensures your safety but also prolongs the life of your tires and enhances your driving experience.
