4 Reasons Honda CRV Tire Pressure Light Keeps Coming On [+Fixes!]

A blinking or illuminated tire pressure light on your Honda CRV dashboard warns you that one or more tires have gone flat. In such a case, your first approach would be to refill the tires. 

But what if your Honda CRV tire pressure light keeps coming on? Certain facts can cause such a scenario. These include: 

• temperature fluctuations due to weather change, 
• flat tires, 
• TPMS system malfunctions, 
• installing new tires, and 
• using tire sealants

To get rid of the issue, you may need to refill the tires, replace or repair any bad sensors, and repair the TPMS system. Let’s find out the details of these solutions.

What Does Honda CRV Tire Pressure Light Mean?

The Tire Pressure Monitoring System, or TPMS, is a safety feature in the Honda CRV. This system incorporates a warning light that illuminates and warns you when a tire’s pressure becomes significantly low. 

On selected Honda models like the CRV, the multi-information display will indicate which tire is low along with a checked tire pressure message. The low tire pressure indicator in the shape of a tire cross-section will light up on the instrument panel. 

There’s also an indicator with the letters TPMS that will light up if there’s a fault in the system itself. This alert means a visit to the service department is necessary. 

The pattern of tire pressure light illumination signifies different scenarios. Check out the table below showing what the Honda CRV Tire Pressure Light Means based on different illumination patterns. 

The Role of Tire Pressure Light in Honda CRV

In the Honda CRV, the TPMS constantly monitors each tire’s air pressure using sensors installed within them. According to the American Automobile Association, there is a minimum tire pressure requirement for safe driving. 

If there is a significant drop in pressure (usually below 25% of the recommended level), the system triggers the tire pressure light on the dashboard. This visual indicator alerts drivers to check their tires and take prompt action if necessary.

However, you can’t rely only on the tire pressure monitoring system instead of regularly checking your tire pressure. On the whole, the tire pressure light serves the following role:

• Warns drivers about low tire pressure while driving.
• Helps to maintain optimal tire pressure
• Prevents unusual tire wear due to low tire pressure
• Aids in vehicle handling
• Prevents decreased traction due to over-inflation of tires. 
• Facilitates ideal fuel economy

troubleshooting guide for Honda CRV Tire Pressure Light Keeps Coming On

We have already highlighted some of the common reasons why the Honda CRV tire pressure light coming on. Now it’s time to discuss them in detail, along with their potential fixes. 

1. One or Multiple Tires Are Flat

As you know, the tire pressure monitoring system (TPMS) in your CRV is an essential feature designed to detect any deviations in tire pressure, including the occurrence of a flat tire. 

If you notice that the tire pressure light illuminates while driving, this is likely due to the system detecting low tire pressure or a potential flat tire situation. 

Potential Fix

If you observe visibly deflated tires, it’s crucial not only to refill them with the appropriate amount of air but also to inspect their condition for any punctures or leaks thoroughly. 

A reliable digital gauge to manually measure and adjust air pressure in all four tires according to the recommended levels should be carried out regularly. 

Professional assistance may be required if you are uncertain about fixing a damaged or flat tire properly.

2. Temperature Fluctuation Due to Weather Change

In cold weather, the temperature drops significantly throughout the season. Naturally, the temperature inside the tires will also decrease. 

But the fact is that it significantly affects tire pressure. According to the ideal gas law, if the temperature of a given volume (closed system) is decreased, the pressure will also be decreased. 

Since a tire acts like a closed system, a decrease in temperature will eventually lead to reduced pressure. This effect becomes more significant when the temperature drops below the freezing point. 

The opposite happens when the temperature rises more than when you refill your tire. As a result, the TPMS will trigger the warning light. 

Potential Fix

If the temperature in your area increases or decreases, and the tire pressure light keeps coming on, it doesn’t mean the air leaks out. 

Rather, it’s because the pressure inside the tire is increased or decreased. In this case, follow the steps mentioned below:

• Step-1: Reset the tire pressure before winter or summer comes. 
• Step-2: If the tire pressure light still comes on, refill the tire to the set level. 

3. Tire Pressure Monitoring System Malfunction

When we notice the tire pressure light keeps coming on continuously, the initial thought that comes to mind is that the system is malfunctioning. 

This is what many Honda CRV owners express in forums or communities. Luckily, the Honda CRV is a vehicle that suffers less commonly from this type of malfunction. 

Yet, different sensors attached to the tires can be faulty due to age or physical damage. So, if you have found that the tire pressure is at the optimum level, but the warning light is coming on, the system itself can be blamed. 

Potential Fix

To fix a faulty tire pressure monitor system, the only option you have is to get it inspected by an expert mechanic. The mechanic can be either from your dealership or your nearby repair shop. 

In the event that any of the sensors attached to your system are damaged or malfunctioning, the mechanic will replace them. 

4. Using Tire Sealants

Tire sealants are quite popular for preventing and repairing tire punctures. Sealants can be adhesive or adhesive-free. However, both types of sealants are injected through the valve. 

Though it’s confusing whether tire sealants cause tire pressure lights to come on, we can’t ignore this fact completely. 

Even many experts suggest avoiding the use of tire sealants. This is because the tire pressure monitor system can start malfunctioning if the sealants come into contact with the sensor. 

This can eventually lead to false readings, and you end up with   illuminated tire pressure light. 

Potential Fix

Once you’ve confirmed that the issue is caused by using sealants, the best solution is to avoid them. 

However, sealants can be your only option when you’re in a roadside emergency. In that case, we recommend injecting the sealant with the help of an expert mechanic. Besides, make sure tire pressure sensors are properly cleaned.

How to Reset Honda CRV Tire Pressure Sensor Light? top 2 method

Sometimes resetting the tire pressure monitor system is necessary even after you have fixed the tire pressure light issue. Thankfully, resetting the tire pressure monitor system of a Honda CRV is an easy task. 

All you need to do is follow the steps mentioned below. However, before you start, don’t forget to refill your tires properly and park the vehicle on a flat surface. Here we go:

Resetting TPMS on Models With Touch Screen

Modern Honda CRV models come with a touchscreen display, which brings changes to the resetting process. Follow the steps:

• Step-1: First, go to the menu and select “settings.”
• Step-2: If there is the “Vehicle” or “Customize settings” option, select any of them. Otherwise, go to the next step.
• Step-3: Press on “TPMS Calibration.”
• Step-4: Click “Calibrate’ and then select the “Initialize” option.
• Step-5: Confirm your actions by clicking on the “Yes” option. 
• Step-6: Now, drive your CRV for at least 20 minutes. Hopefully, your TPMS will be reset within this period.

Resetting TPMS on Models Without Touch Screen

If you own a Honda CRV model that doesn’t possess a touchscreen display, check out the steps below:

• Step-1: Find the TPMS button on the left side of the steering wheel. This button is typically located beneath or adjacent to the steering column. 
• Step-2: Press and hold the TPMS button until the warning light starts blinking. 
• Step-3: Release the button as the light blinks and drive your CRV for at least 20 minutes. Hopefully, this will reset the TPMS system. 

Risk of Avoiding Tire Pressure Light Keeps Coming On Continuously

If we compare tire pressure with most other warning lights in your Honda CRV, the TPMW light will be on the less severe side. 

Still, avoiding a continuously illuminating tire pressure light can warn you of something dangerous to come. There are certain risks involved if the tire pressure light is ignored. Check them out below:

• You’ll get significantly reduced fuel economy
• Your ride will be less comfortable 
• You’ll face difficulties in handling due to reduced traction
• The lifespan of your tires will be shortened
• Your journey will be unsafe.
