The most common reasons a Ram ProMaster City 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 ProMaster City 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 of a TPMS control module failure are failing to alert the driver of underinflation or overinflation of one or more tires, failure to communicate with the body control module or TPMS sensors, or erroneously reporting incorrect tire pressure.

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 ProMaster City

When addressing the tire pressure warning light in your Ram ProMaster City, it's essential to adopt a diagnostic approach that prioritizes straightforward solutions before delving into more complex issues. Start by checking the tire pressure in all four tires, ensuring they are inflated to the manufacturer's recommended levels. This simple step can often resolve the warning light if it was triggered by low pressure. If the tires are adequately inflated, turn off the ignition and restart the vehicle; this can sometimes reset the system and turn off the warning light. If the light remains illuminated, inspect for any visible leaks or damage to the tires, as these can also trigger the alert. Should you suspect a malfunctioning tire pressure monitoring system (TPMS) sensor, consider replacing it, as faulty sensors are a common culprit. Additionally, resetting the tire pressure in the early morning when temperatures are cooler can help prevent false alerts. Understanding how the TPMS operates in your vehicle will further aid in diagnosing the issue effectively. Regular maintenance of your tire pressure not only ensures safety but also enhances the longevity of your tires and the efficiency of the TPMS system. By following this methodical approach, you can effectively troubleshoot and resolve the tire pressure warning light issue in your Ram ProMaster City.

Troubleshooting Tire Pressure Warning Light in Ram ProMaster City

When dealing with the tire pressure warning light in your Ram ProMaster City, it's essential to understand the common problems that may be at play. One of the most frequent culprits is a significant drop in tire pressure, which can occur due to punctures, leaks, or even temperature changes affecting the air inside the tires. Additionally, tire pressure monitoring system (TPMS) faults can trigger the warning light, indicating that the sensors may be malfunctioning or need recalibration. It's also worth noting that if the vehicle has recently been serviced or had tires replaced, the TPMS may require a reset to recognize the new tire pressures. In some cases, simply restarting the vehicle can clear the warning light if it was triggered by a temporary glitch. However, if the light remains illuminated after checking tire pressures and resetting the system, it may be necessary to inspect and potentially replace faulty sensors to ensure accurate monitoring. By being aware of these common issues, you can take proactive steps to maintain your vehicle's safety and performance.

What Should You Do When the Tire Pressure Warning Light Stays On in a Ram ProMaster City?

When the tire pressure warning light remains illuminated in your Ram ProMaster City, it is crucial to act promptly to avoid serious safety risks and potential damage to your vehicle. Ignoring this warning can lead to decreased tire performance, increased wear, and even tire blowouts, which can compromise your safety on the road. Start by checking the tire pressure in all tires, as low pressure can significantly affect handling and fuel efficiency. If you discover that the pressure is below the recommended levels, inflate the tires accordingly. However, if the warning light persists even after correcting the tire pressure, you must reset the Tire Pressure Monitoring System (TPMS) to ensure it accurately reflects the current tire conditions. This process is straightforward and typically involves locating the TPMS reset button beneath the steering wheel. Remember, the TPMS is designed to keep you informed about your tire health, and addressing any issues immediately not only enhances your vehicle's performance but also safeguards your well-being while driving.
