The most common reasons a Ram 3500 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 Ram 3500 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.

Troubleshooting Tire Pressure Warning Light in a Ram 3500

When dealing with a tire pressure warning light in your Ram 3500, it's essential to adopt a systematic diagnostic approach. Start by visually inspecting each tire for any signs of damage or leaks, as a simple puncture or slow leak can often be the culprit behind the warning light. If you identify a tire that appears to be losing air, address the issue by repairing or replacing it as necessary. Next, if all tires seem intact, proceed to reset the Tire Pressure Monitoring System (TPMS) by locating the reset button, usually found beneath the steering wheel. Press and hold this button until the warning light blinks three times, then release it. After resetting, start your vehicle and allow approximately 20 minutes for the system to recalibrate and recognize the correct tire pressures. Finally, ensure that all tires are inflated to the manufacturer's recommended PSI, which can typically be found on a sticker inside the driver’s door. Once the tires are properly inflated, the warning light should turn off automatically, confirming that your tire pressure system is functioning correctly. By following these steps, you can effectively troubleshoot and resolve the tire pressure warning light issue, ensuring a safer driving experience.

Troubleshooting Tire Pressure Warning Light in a Ram 3500

When dealing with a tire pressure warning light in your Ram 3500, it's essential to understand the common problems that could trigger this alert. One frequent culprit is a tire that is losing air due to a leak or damage, which can often be identified by visually inspecting the tires for punctures or irregular wear. Additionally, if you've recently changed your tires or wheels, the tire pressure monitoring system (TPMS) may need recalibration to recognize the new components. Prolonged periods of inactivity can also lead to natural deflation, so checking the pressure regularly is crucial. If the warning light blinks, it may indicate a malfunction in the tire pressure sensors or the receiver, suggesting that a reset of the TPMS could be necessary. By systematically checking these potential issues and ensuring all tires are inflated to the recommended pressure, you can effectively troubleshoot and resolve the tire pressure warning light concern, ensuring a safer driving experience.

Why is the Tire Pressure Warning Light Staying On in a Ram 3500?

When the tire pressure warning light remains illuminated in your Ram 3500, it is crucial to take immediate action to ensure your safety and the longevity of your vehicle. Ignoring this warning can lead to serious consequences, such as reduced traction, increased tire wear, and even tire blowouts, which can compromise your control over the vehicle. Common culprits for this warning include leaking tires, faulty tire pressure monitoring systems, or simply low air pressure due to temperature fluctuations or air leaks. If you've recently changed tires or if your truck has been stationary for an extended period, these factors could also trigger the warning light. To address the issue, start by checking the air pressure in all tires and inspecting them for visible leaks or damage. If the problem persists after ensuring proper inflation and tire condition, it may be time to consult a professional to evaluate the tire pressure monitoring system. Taking these steps not only enhances your driving safety but also promotes better tire maintenance, ultimately saving you from costly repairs down the line.
