The most common reasons a 2019 Ram 1500 Classic 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 2019 Ram 1500 Classic 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 tire pressure warning light that stays on in a 2019 Ram 1500 Classic?

To effectively diagnose a tire pressure warning light that remains illuminated in your 2019 Ram 1500 Classic, begin with the simplest and most straightforward approach. First, manually check the tire pressure in all four tires, including the spare, using a reliable tire pressure gauge. Ensure that each tire is inflated to the manufacturer's recommended PSI, as incorrect pressure is a common cause for the warning light. Next, conduct a visual inspection of the tires for any visible damage such as punctures, cuts, or bulges, which could indicate a loss of pressure. If the tire pressure is correct and no damage is found, proceed to reset the tire pressure monitoring system (TPMS) according to your vehicle's manual, as this can sometimes resolve the issue. Additionally, inspect the valve stems for any signs of wear or leaks, as faulty valve stems can also lead to pressure problems. If the warning light persists after these checks, consider using a diagnostic tool to scan for fault codes related to the TPMS, which can help identify more complex issues. By following these steps, you can effectively troubleshoot the tire pressure warning light and determine whether further professional assistance is needed.

What could cause the tire pressure warning light to remain on in a 2019 Ram 1500 Classic?

When the tire pressure warning light remains on in your 2019 Ram 1500 Classic, it’s crucial to identify the underlying issues that may be causing this alert. One of the most frequent reasons is low tire pressure, which can be easily remedied by checking and inflating the tires to the recommended levels. If the tire pressure is adequate, the problem might stem from a faulty tire pressure sensor that may need replacement. Additionally, the tire pressure monitoring system could require recalibration to ensure it functions correctly, a process that can often be completed by following the manufacturer’s instructions. Electrical problems, such as damaged wiring or blown fuses, can also lead to the warning light staying on, so a thorough inspection of the vehicle’s electrical system is advisable. Lastly, environmental factors like significant temperature changes or driving on rough terrain can impact tire pressure, making it essential to monitor your tires for any signs of damage or irregularities. By addressing these common issues, you can effectively troubleshoot and resolve the persistent tire pressure warning light in your Ram 1500 Classic.

What immediate steps should be taken if the tire pressure warning light remains on in a 2019 Ram 1500 Classic?

When the tire pressure warning light remains illuminated in your 2019 Ram 1500 Classic, it is crucial to act promptly to avoid potential safety hazards and costly repairs. Ignoring this warning can lead to decreased vehicle performance, increased tire wear, and even blowouts, which pose serious risks on the road. Start by checking the tire pressure in all four tires with a reliable gauge, ensuring they meet the manufacturer's specifications. If you find any tires underinflated, use a quality air compressor to inflate them to the correct levels. Next, inspect each tire for visible damage, such as punctures or bulges, as these issues can compromise safety and require immediate attention. After addressing any pressure discrepancies or damage, reset the tire pressure monitoring system according to your owner's manual. If the warning light persists, it is essential to consult a professional mechanic, as there may be a deeper issue with the monitoring system that needs expert diagnosis. Taking these steps not only enhances your vehicle's safety but also prolongs the life of your tires, ensuring a smoother and more secure driving experience.
