The most common reasons a 2017 Mitsubishi Outlander 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 2017 Mitsubishi Outlander 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 the tire pressure warning light on a 2017 Mitsubishi Outlander?

To effectively diagnose the tire pressure warning light on your 2017 Mitsubishi Outlander, begin with a straightforward approach that prioritizes simple solutions before delving into more complex diagnostics. Start by checking the tire pressure in all four tires using a reliable tire pressure gauge, ensuring that the readings align with the recommended PSI found in your owner's manual or on the driver's side door jamb. Next, conduct a thorough visual inspection of each tire for any visible damage, such as cuts, punctures, or foreign objects lodged in the tread, as these can directly affect tire pressure. If the tire pressure appears normal, consider resetting the Tire Pressure Monitoring System (TPMS) according to the instructions provided in your owner's manual, as this can sometimes resolve temporary warning light triggers. Additionally, driving the vehicle for a short distance at varying speeds may help recalibrate the system and turn off the warning light. However, if the light remains illuminated after these steps, it may indicate a more serious issue with the TPMS sensors or system, at which point seeking assistance from a qualified mechanic or dealership is recommended for further diagnosis and repair. By following this methodical approach, you can efficiently address the tire pressure warning light and ensure your vehicle's safety on the road.

What could be causing the tire pressure warning light to stay on in a 2017 Mitsubishi Outlander?

When the tire pressure warning light remains illuminated in your 2017 Mitsubishi Outlander, it can be frustrating, but understanding the common problems can help you diagnose the issue. One of the primary culprits is low tire pressure, which can occur due to natural air loss or temperature fluctuations. Regularly checking and inflating your tires to the manufacturer's recommended pressure is essential. If the pressure is adequate, the problem may lie with a faulty tire pressure sensor, which could require recalibration or replacement. Additionally, consider the possibility of dead sensor batteries, as some systems rely on battery-operated sensors that can fail over time. If you suspect a more complex issue, such as a malfunction within the tire pressure monitoring system itself, diagnostic testing may be necessary. Lastly, inspect your tires for any leaks or punctures, as these can lead to pressure loss and trigger the warning light. By systematically addressing these potential issues, you can effectively troubleshoot and resolve the tire pressure warning light concern in your Outlander.

How urgent is it to address the tire pressure warning light that stays on in a 2017 Mitsubishi Outlander?

Addressing the tire pressure warning light in your 2017 Mitsubishi Outlander is not just a matter of convenience; it is a critical safety concern that requires immediate attention. When this warning light remains illuminated, it indicates that your tires may be underinflated, which can severely compromise your vehicle's handling and braking capabilities. Driving on underinflated tires not only increases the risk of a blowout but also leads to uneven tire wear and decreased fuel efficiency, ultimately resulting in costly repairs. Moreover, the potential for losing control of your vehicle, especially in adverse weather conditions, makes it imperative to act swiftly. To ensure your safety and the longevity of your tires, check the tire pressure as soon as possible, inflate them to the recommended levels found in your owner's manual, and investigate any underlying issues with the tire pressure monitoring system. Ignoring this warning could lead to dangerous situations on the road, making prompt action essential.
