2022 Dodge Challenger TPMS Light On: Diagnosis & Fixes

Seeing the Tire Pressure Monitoring System (TPMS) warning light illuminate on your 2022 Dodge Challenger can be unsettling, especially when you've already checked your tire pressures and confirmed they are correct. This common scenario indicates that while your tires might be properly inflated, there's an underlying issue within the TPMS itself that needs attention. It's more than just a low tire; it's a signal that a sensor, module, or system component is malfunctioning, preventing your Challenger from accurately monitoring tire pressure and potentially compromising a crucial safety feature. Addressing this promptly ensures your vehicle can continue to alert you to actual low-pressure situations, maintaining optimal handling, fuel efficiency, and tire longevity.

What the TPMS Light Means on Your 2022 Dodge Challenger

The Tire Pressure Monitoring System (TPMS) is a vital safety feature designed to warn you when one or more of your tires are significantly under-inflated, which can lead to unsafe driving conditions, premature tire wear, and decreased fuel economy. Each tire (and sometimes the spare) contains a sensor that transmits pressure data wirelessly to your Challenger's onboard computer.

When the TPMS light illuminates on your dashboard, it's communicating one of two primary messages:

• Solid Amber Light: This typically means one or more of your tires are under-inflated by 25% or more below the recommended PSI, or there is a system malfunction. In the context of this article, if your pressures are correct, a solid light points to a system fault.
• Flashing Amber Light (for 60-90 seconds upon start-up, then solid): This almost always indicates a malfunction within the TPMS itself, such as a dead sensor battery, a faulty sensor, or an issue with the TPMS control module. The system is unable to monitor tire pressures reliably.

Understanding this distinction is crucial for proper diagnosis. If your 2022 Dodge Challenger's TPMS light is on and you've confirmed correct tire pressures, you are dealing with a system component failure rather than just a low tire.

What drivers notice on this 2022 Dodge Challenger

Drivers of the 2022 Dodge Challenger often first notice the TPMS light as a solid amber icon on the dashboard, resembling a cross-section of a tire with an exclamation point inside. Initially, the natural reaction is to check tire pressures, but for this specific issue, the light persists even after adjusting all tires to the recommended PSI. This can be frustrating, as the primary purpose of the system is to provide peace of mind regarding tire safety. The system might also display a 'Service TPMS' message or specific tire pressure readings that are incorrect or missing altogether, further indicating a system fault rather than just a low tire.

Symptoms and warning signs

When the 2022 Dodge Challenger TPMS light is on despite correct tire pressure, you might observe several related symptoms:

• Solid amber TPMS light: The most obvious sign, indicating a system malfunction rather than a low tire. This light will remain illuminated as long as the fault is present.
• 'Service TPMS' message: A direct message on the instrument cluster, prompting system inspection. This often accompanies a flashing TPMS light.
• Incorrect tire pressure readings: The display shows wildly inaccurate pressures for one or more tires, such as 0 PSI, or pressures significantly different from your manual gauge readings.
• Missing tire pressure readings: One or more tire positions show dashes ('--') or no data displayed on the infotainment screen or instrument cluster.
• Flashing TPMS light (on start-up): If the light flashes for 60-90 seconds upon starting the vehicle before remaining solid, it often indicates a TPMS sensor fault or system error, such as a dead sensor battery or a communication issue.
• Inability to reset TPMS: Attempts to reset the system (e.g., by driving for a certain period, or through the infotainment system's settings) are unsuccessful, and the light quickly reappears.
• No warning for actual low pressure: If the system is faulty, it may not alert you to a genuinely under-inflated tire, which is a significant safety concern.

How to verify and confirm the issue

Confirming the exact cause of a persistent 2022 Dodge Challenger TPMS light requires more than just a visual check. Here’s how to systematically verify the issue:

• Manually check tire pressure: Use a reliable, calibrated tire gauge to ensure all four road tires (and the spare, if equipped with a sensor) are at the manufacturer's recommended PSI. This information is typically found on a sticker inside the driver's door jamb or in your owner's manual. This crucial first step rules out actual low pressure as the cause.
• Perform a visual inspection: Carefully inspect the valve stems on all tires. TPMS sensors are often integrated into the valve stem. Look for any obvious damage, corrosion, or signs of tampering. Sometimes, a damaged valve stem can prevent the sensor from transmitting.
• Check for recent tire service: Did the light come on after a tire rotation, replacement, or repair? Improper handling during tire service is a common cause of sensor damage or a loss of programming.
• Test drive: After ensuring correct tire pressure, drive the vehicle for at least 10-15 minutes at speeds above 15-20 mph. Some systems require this to recalibrate or relearn sensor positions, especially after pressure adjustments or tire rotations. If the light persists, the issue is more complex.
• Use an OBD-II scanner with TPMS capabilities: A specialized TPMS scan tool is essential. While a generic OBD-II scanner can read general powertrain codes, a TPMS-specific tool can:
  • Activate individual sensors.
  • Read sensor IDs, battery status, and current pressure/temperature data directly from each sensor.
  • Identify which specific sensor is faulty or has a dead battery.
  • Perform a TPMS relearn procedure, if necessary.
• Check for Technical Service Bulletins (TSBs): Consult a Dodge dealership or a reputable automotive information service for any known TSBs related to TPMS issues on the 2022 Challenger. Manufacturers sometimes release specific fixes or software updates for common problems. You can also visit the Dodge vehicle hub for more model-specific information.

Common causes (most likely first)

Several factors can cause the 2022 Dodge Challenger TPMS light to remain on, even with proper tire pressure:

• Faulty TPMS sensor: This is the most common cause. Sensors have internal batteries that eventually die (typically 5-10 years, but can vary), or they can be damaged during tire service. A dead or malfunctioning sensor won't transmit data, triggering the light. This often manifests as a flashing TPMS light on start-up.
• TPMS sensor battery depletion: The internal battery in each sensor has a finite lifespan. Unlike car batteries, these are usually non-replaceable, meaning the entire sensor needs to be replaced once its battery dies.
• TPMS sensor damage: Impact from potholes, curb strikes, or improper tire mounting/dismounting can physically damage the sensor itself, breaking its internal components or antenna.
• Loss of sensor programming/relearning: Sensors sometimes lose their programming or connection to the TPMS module, especially after tire rotations, replacements, or battery disconnections. They need to be
