The most common reasons a 2021 Mitsubishi Mirage 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 2021 Mitsubishi Mirage 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 2021 Mitsubishi Mirage?

To effectively diagnose the tire pressure warning light issue on your 2021 Mitsubishi Mirage, begin with a straightforward approach that prioritizes simpler 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. Next, inspect each tire for visible damage, such as punctures or bulges, which could indicate a leak or other issues. If the tire pressure is correct and the tires appear undamaged, consider resetting the tire pressure monitoring system (TPMS) as outlined in your vehicle's manual, as this can sometimes resolve false warnings. After making any necessary adjustments, take your vehicle for a short drive; the system may require some time to recalibrate and turn off the warning light. If the light remains illuminated despite these efforts, it may be time to consult a mechanic for a more comprehensive diagnosis, as there could be underlying issues that require professional attention. By following this methodical approach, you can efficiently address the tire pressure warning light concern and ensure your vehicle is safe to drive.

What could cause the tire pressure warning light to remain on in a 2021 Mitsubishi Mirage?

When the tire pressure warning light remains illuminated in a 2021 Mitsubishi Mirage, it can be attributed to several common problems that DIYers can investigate. The most frequent culprit is low tire pressure, which can easily be checked using a tire pressure gauge. Ensuring that all tires are inflated to the manufacturer's recommended levels is crucial for both safety and performance. If the pressure is adequate, the issue may lie with a faulty tire pressure sensor, which could be malfunctioning and failing to provide accurate readings. Additionally, the sensor's battery may be depleted, leading to a persistent warning light. Inspecting the wiring and connections associated with the tire pressure sensor is also essential, as damaged or loose connections can disrupt communication with the vehicle's system. Lastly, if all else seems normal, recalibrating the tire pressure monitoring system may be necessary to reset the warning light. By systematically addressing these potential issues, you can effectively troubleshoot the tire pressure warning light and ensure your Mitsubishi Mirage remains safe and roadworthy.

How urgent is it to address the tire pressure warning light that stays on in a 2021 Mitsubishi Mirage?

Addressing the tire pressure warning light in your 2021 Mitsubishi Mirage is not just a matter of convenience; it is a critical safety concern that requires immediate attention. Ignoring this warning can lead to serious consequences, including compromised vehicle handling and braking performance, which significantly increases the risk of accidents. Additionally, driving on underinflated tires can cause uneven wear, leading to premature tire replacements and unnecessary expenses. Furthermore, maintaining proper tire pressure is essential for optimal fuel efficiency; neglecting this can result in higher fuel consumption, impacting your overall driving costs. Therefore, it is crucial to regularly check your tire pressure, inflate your tires to the recommended levels, and inspect for any damage. If the warning light persists despite these measures, seeking professional assistance is advisable to ensure your vehicle remains safe and efficient on the road. Taking these steps not only protects your vehicle but also enhances your driving experience.
