The most common reasons a 2009 Mitsubishi Eclipse 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 2009 Mitsubishi Eclipse 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 2009 Mitsubishi Eclipse?

To effectively diagnose the tire pressure warning light issue on your 2009 Mitsubishi Eclipse, begin with a thorough check of the tire pressure in all four tires, ensuring they meet the recommended levels outlined in your owner's manual. This initial step is crucial as improper tire pressure is a common cause of the warning light activation. Next, inspect each tire for visible damage, such as punctures or bulges, and look for any foreign objects that may be causing a leak. If the tire pressure is correct and the tires appear undamaged, proceed to reset the tire pressure monitoring system, as some vehicles require this after adjustments. If the warning light persists, it may indicate a malfunction in the tire pressure sensors, which should be examined by a professional. Finally, using a diagnostic tool to scan for error codes can provide further insights into any underlying issues with the tire pressure monitoring system, allowing you to address the problem effectively. By following this structured approach, you can systematically identify and resolve the cause of the tire pressure warning light on your vehicle.

What could be causing the tire pressure warning light to remain on in a 2009 Mitsubishi Eclipse?

When the tire pressure warning light remains illuminated in your 2009 Mitsubishi Eclipse, it can be frustrating, but understanding the common problems can help you diagnose the issue. The most frequent cause is low tire pressure, which can easily be checked with a tire pressure gauge. Ensure all tires are inflated to the manufacturer's recommended levels, as even a slight drop can trigger the warning light. If the pressure is adequate, the problem may lie with a faulty tire pressure sensor, which may require replacement if it fails to provide accurate readings. Additionally, sensor calibration issues can arise, necessitating a recalibration to ensure proper functionality. Electrical problems within the tire pressure monitoring system, such as damaged wiring or loose connections, can also lead to persistent warning lights. Lastly, a malfunctioning control module may be at fault, and diagnosing this issue may require professional assistance. By systematically addressing these potential causes, you can effectively troubleshoot and resolve the tire pressure warning light issue in your vehicle.

How urgent is it to address the tire pressure warning light that stays on in a 2009 Mitsubishi Eclipse?

Addressing the tire pressure warning light in your 2009 Mitsubishi Eclipse is not just a matter of convenience; it is a critical safety issue that requires immediate attention. When this warning light remains illuminated, it signals that your tires may be underinflated, which can severely compromise your vehicle's handling and braking capabilities. This is particularly dangerous in adverse weather conditions, where the risk of accidents increases significantly. Moreover, driving on underinflated tires can lead to uneven wear, necessitating costly premature tire replacements. Additionally, low tire pressure can negatively impact your fuel efficiency, resulting in higher fuel costs over time. Ignoring this warning can also lead to tire damage, increasing the likelihood of a blowout while driving. Therefore, it is essential to check and adjust your tire pressure according to the manufacturer's specifications as soon as the warning light activates, ensuring both your safety and the longevity of your vehicle.
