2021 Nissan Rogue Tire Maintenance Light

Alright, so your 2021 Nissan Rogue's tire pressure monitoring system (TPMS) light is on. Don't panic! It doesn't automatically mean you have a flat or a serious problem. More often than not, it's something relatively straightforward. This article will walk you through diagnosing and resolving common TPMS issues specific to the 2021 Rogue, assuming you have some basic mechanical knowledge and tools.

Understanding the 2021 Rogue TPMS

Before diving into troubleshooting, let's quickly review how the 2021 Rogue's TPMS works. It's a direct system, meaning each wheel has a sensor inside the tire. These sensors measure the tire pressure and transmit this data wirelessly to the vehicle's electronic control unit (ECU), specifically the body control module (BCM). The BCM then compares these readings to a preset threshold. If one or more tires fall below this threshold (typically around 28 PSI), the TPMS light illuminates on your dashboard.

There are two types of TPMS lights you might see. A solid light indicates that one or more tires are underinflated. A flashing light usually signifies a more serious problem, such as a malfunctioning sensor, a system fault, or interference.

Common Causes & Troubleshooting Steps

Let's tackle the most likely culprits in order of ease of diagnosis and repair:

1. Low Tire Pressure (Solid TPMS Light)

This is the most common reason for a solid TPMS light. Temperature fluctuations significantly affect tire pressure. As the temperature drops, the air inside your tires contracts, leading to lower pressure. Conversely, warmer temperatures cause the pressure to increase.

Diagnosis:

• Visual Inspection: Check each tire for obvious signs of damage, such as cuts, bulges, or embedded objects.
• Tire Pressure Gauge: Use a reliable tire pressure gauge to check the pressure in all four tires. Compare these readings to the recommended tire pressure listed on the sticker inside your driver's side door jamb (usually around 33 PSI, but confirm yours). Don't rely solely on the TPMS reading, as it can sometimes lag or be slightly inaccurate.

Resolution:

• Inflate Tires: Inflate any tires that are below the recommended pressure. Overinflation is also bad, so avoid exceeding the maximum pressure listed on the tire sidewall.
• Check for Leaks: After inflating, listen for hissing sounds around the tire, valve stem, and wheel. If you suspect a leak, spray soapy water on these areas. Bubbles will form where air is escaping. If you find a leak, get the tire repaired or replaced by a professional.

Important Note: Even if only one tire is low, it's a good idea to check and adjust the pressure in all four tires to ensure even wear and optimal handling.

2. TPMS Sensor Battery Failure (Flashing TPMS Light)

Each TPMS sensor has a battery that powers its radio transmitter. These batteries typically last for 5-7 years, depending on usage and environmental conditions. If the TPMS light is flashing, a sensor battery may be dying. It's important to note that the 2021 Rogue has a complex system, and sometimes a dying sensor will also trigger a solid light, so this is not always a definitive diagnosis.

Diagnosis:

• Scan Tool: A professional-grade scan tool that can read TPMS data is the best way to diagnose a sensor failure. These tools can display individual sensor IDs, battery status, and pressure readings. Many aftermarket scan tools can also perform this function.
• Listen Closely: You may hear no error beep when starting the car.
• Visual Inspection (during tire change): If you're already getting new tires, you can visually inspect the sensors for physical damage when the tires are dismounted.

Resolution:

• Sensor Replacement: The only real solution for a dead sensor battery is to replace the entire sensor. This involves dismounting the tire, removing the old sensor, installing a new sensor, and re-mounting the tire. This is a job best left to a tire professional unless you have experience with tire changing and TPMS service.
• Sensor Programming/Relearning: After replacing a sensor, it needs to be programmed or relearned by the vehicle's BCM. Some sensors are pre-programmed, while others require programming using a TPMS programming tool. The 2021 Rogue typically requires a relearn procedure, which can sometimes be initiated through the vehicle's infotainment system (check your owner's manual) or using a scan tool.

3. TPMS Sensor Damage

TPMS sensors are vulnerable to damage from impacts, corrosion, and improper tire service. A bent or broken sensor can cause inaccurate readings or complete failure, leading to a flashing TPMS light.

Diagnosis:

• Visual Inspection (during tire change): As mentioned earlier, visually inspect the sensors for any signs of damage when the tires are dismounted. Look for cracks, corrosion, or broken components.
• Scan Tool: A scan tool can often identify a sensor that is transmitting erratic or nonsensical data, which can indicate damage.

Resolution:

• Sensor Replacement: Replace any damaged TPMS sensors.
• Sensor Programming/Relearning: Follow the same programming/relearning procedure as outlined for sensor battery failure.

4. Interference

Although less common, radio frequency (RF) interference can sometimes disrupt the TPMS signal. This is more likely to occur in areas with high levels of RF activity, such as near cell towers or radio transmitters. Aftermarket electronic devices could also be a culprit.

Diagnosis:

• Temporary Interference: If the TPMS light comes on suddenly in a specific location and then disappears when you move, interference is a likely cause.
• Rule Out Other Causes: Before attributing the problem to interference, rule out low tire pressure, sensor failures, and system faults.

Resolution:

• Move Location: If you suspect interference, drive the vehicle to a different location. If the TPMS light clears after driving for a short distance, interference was likely the cause.
• Check for Aftermarket Electronics: Temporarily disconnect any aftermarket electronic devices (e.g., dash cams, radar detectors) to see if they are causing interference.

5. TPMS System Fault

In rare cases, the TPMS light may indicate a more serious fault within the TPMS system itself. This could involve a problem with the BCM, wiring, or other components.

Diagnosis:

• Scan Tool: A scan tool can often retrieve diagnostic trouble codes (DTCs) related to the TPMS system. These codes can provide valuable clues about the nature of the fault. Common codes might indicate a loss of communication with one or more sensors or a problem with the BCM.
• Wiring Inspection: Check the wiring harness and connectors for any signs of damage, corrosion, or loose connections.

Resolution:

• Professional Diagnosis: A TPMS system fault is usually beyond the scope of most DIYers and requires professional diagnosis and repair. A qualified mechanic can use specialized tools and diagnostic procedures to pinpoint the source of the problem.

Resetting the TPMS Light

After addressing the underlying cause of the TPMS light, you may need to reset the system. The 2021 Rogue's TPMS typically resets automatically after driving for a few minutes at a speed above 25 mph. However, in some cases, you may need to perform a manual reset using a scan tool or through the vehicle's infotainment system (refer to your owner's manual for instructions).

Tools You'll Need

Disclaimer: Tire pressure monitoring systems are safety-critical components. If you are not comfortable working on your vehicle's TPMS, it is best to seek professional assistance from a qualified mechanic. Incorrect installation or programming of TPMS sensors can lead to inaccurate readings and compromise vehicle safety.
