The most common reasons a 2015 Ram 2500 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 Ram 2500 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 Ram 2500?

When faced with a persistent tire pressure warning light on your 2015 Ram 2500, start by checking the tire pressure in all four tires, ensuring they are inflated to the levels specified in your vehicle's manual. This simple step can often resolve the issue if the light is triggered by low pressure. Next, visually inspect each tire for any signs of damage, such as punctures or bulges, which could indicate a leak or other problems. If the tires appear to be in good condition, attempt to reset the tire pressure monitoring system following the manufacturer's instructions; sometimes, the system may need a refresh to clear the warning light. If the light remains on, examine the tire pressure sensors for any signs of malfunction or damage, as faulty sensors can also trigger the warning. Finally, if all else fails, using a diagnostic tool to scan for fault codes related to the tire pressure monitoring system can help identify any underlying issues that require further attention. By following this structured approach, you can effectively troubleshoot the warning light and ensure your vehicle's safety on the road.

What are the common problems that could cause the tire pressure warning light to stay on in a 2015 Ram 2500?

When the tire pressure warning light remains illuminated in a 2015 Ram 2500, it is essential to understand the common problems that could be causing this issue to effectively troubleshoot it. One of the primary culprits is low tire pressure, which can result from a slow leak, temperature fluctuations, or improper inflation. Regularly checking and maintaining the correct tire pressure is crucial for safety and performance. Another potential issue is a faulty tire pressure sensor; if the sensor malfunctions, it may fail to provide accurate readings, leading to the warning light staying on. Additionally, the sensors are equipped with batteries that can deplete over time, necessitating replacement to ensure proper functionality. If you've recently rotated your tires or replaced any sensors, the system may require a relearn procedure to recalibrate the sensors with the vehicle's onboard system. Lastly, inspect the wiring and connections associated with the tire pressure monitoring system, as damaged wires or loose connections can also trigger the warning light. By systematically addressing these common problems, you can effectively resolve the tire pressure warning light issue in your Ram 2500.

What immediate actions should be taken if the tire pressure warning light on a 2015 Ram 2500 remains illuminated?

When the tire pressure warning light on your 2015 Ram 2500 stays illuminated, it signals an urgent need for action to ensure your safety and the vehicle's performance. Ignoring this warning can lead to serious consequences, including tire blowouts or compromised handling, which can endanger you and other road users. Start by checking the tire pressure of all tires, including the spare, using a reliable gauge to confirm they meet the manufacturer's recommended levels. If you find any tires underinflated, inflate them immediately to restore optimal performance. Additionally, inspect each tire for visible damage such as punctures or bulges, as these can exacerbate the issue and lead to further complications if left unaddressed. After adjusting the tire pressure, consult your vehicle's manual to see if you need to reset the tire pressure monitoring system; this step is crucial to ensure the warning light turns off. If the light remains on despite these efforts, it’s essential to seek professional assistance, as there may be underlying issues with the monitoring system that require expert diagnosis. Taking these steps promptly not only enhances your safety but also helps prevent costly repairs down the line.
