The most common reasons a 2015 Mitsubishi Lancer 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 2015 Mitsubishi Lancer 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 are the initial steps to diagnose a persistent tire pressure warning light on a 2015 Mitsubishi Lancer?

To effectively diagnose a persistent tire pressure warning light on your 2015 Mitsubishi Lancer, start with the most straightforward solution: checking the tire pressure. Ensure that all tires are inflated to the manufacturer's recommended levels, as low pressure is a frequent culprit for triggering the warning light. Next, visually inspect each tire for any signs of damage, such as punctures or bulges, which could indicate a leak. If the tires appear to be in good condition, proceed to reset the tire pressure monitoring system by following the instructions in your vehicle's manual. This step can often resolve minor glitches in the system. Additionally, examine the tire pressure sensors for any visible damage or malfunction, as faulty sensors can also cause the warning light to remain illuminated. If, after completing these steps, the warning light persists, it may be time to consult a professional mechanic or dealership for a more thorough diagnosis and repair. By following this methodical approach, you can efficiently troubleshoot the issue and potentially save on repair costs.

What could be causing the tire pressure warning light to stay on in a 2015 Mitsubishi Lancer?

When the tire pressure warning light stays on in a 2015 Mitsubishi Lancer, it is essential to identify the underlying issues to ensure safe driving. The most common reason for this warning light is low tire pressure, which can result from slow leaks, temperature changes, or natural air loss. Additionally, a malfunctioning tire pressure sensor may fail to provide accurate readings, causing the light to remain illuminated. It's also possible that the sensor's battery needs replacement; a dead battery will prevent the sensor from communicating tire pressure data effectively. In some instances, the tire pressure monitoring system may require recalibration, as incorrect calibration can trigger the warning light even when tire pressures are adequate. Furthermore, inspect the wiring and connections for any damage or loose fittings, as these can disrupt the system's communication. Lastly, check for any visible tire damage or punctures, as these can lead to low pressure and activate the warning light. By addressing these potential problems, you can maintain the safety and performance of your vehicle.

What should I do if the tire pressure warning light on my 2015 Mitsubishi Lancer stays on?

When the tire pressure warning light on your 2015 Mitsubishi Lancer remains illuminated, it is crucial to act swiftly to avoid safety hazards and potential damage to your vehicle. Ignoring this warning can lead to decreased handling, increased tire wear, and even blowouts, which pose serious risks while driving. Start by checking the tire pressure in all tires, including the spare, using a reliable gauge to ensure they meet the manufacturer's specifications. If you find any tires underinflated, inflate them accordingly, as proper tire pressure is essential for optimal performance and safety. Additionally, inspect each tire for visible damage, such as punctures or bulges, which could compromise their integrity. 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 is advisable to consult a professional mechanic, as there may be underlying issues with the tire pressure monitoring system that need expert attention. By addressing the tire pressure warning light promptly, you not only enhance your vehicle's safety but also prolong the life of your tires.
