How To Reset Check Anti Pollution System Renault

Renault vehicles are known for their sleek design and innovative technology. However, like any other vehicle, they are not immune to occasional issues. One common problem that Renault owners may encounter is the “Check Anti Pollution System” warning message. This can be a cause for concern, but fortunately, there are steps you can take to reset this warning and get your vehicle back on track. In this article, we will guide you through the process of resetting the check anti-pollution system on your Renault.

Understanding the Check Anti Pollution System Warning

The “Check Anti Pollution System” warning typically indicates an issue with the vehicle’s emissions control system. This system is designed to reduce harmful pollutants released into the atmosphere. When the warning message appears, it means that something is amiss within this system, and it needs to be addressed.

It is important to note that the warning could be triggered by various factors, including faulty sensors, clogged filters, or even a loose gas cap. Therefore, it is crucial to diagnose the root cause of the problem before attempting a reset.

Resetting the Check Anti Pollution System on Your Renault

Resetting the “Check Anti Pollution System” warning on your Renault is a relatively straightforward process. Follow the steps below:

Step 1: Identify the Issue

Before resetting the warning, it is important to determine the underlying cause. This will help you understand if the issue can be resolved without professional assistance or if further action is required. Some common causes of the warning message include a faulty oxygen sensor, a clogged particulate filter, or a malfunctioning catalytic converter.

Step 2: Address the Cause

If you have identified the issue and it is within your capability to address it, do so before proceeding with the reset. For instance, if the gas cap is loose, tighten it securely. Similarly, if a sensor is faulty, you may need to replace it. Keep in mind that some issues may require professional intervention, especially if they involve complex components or systems.

Step 3: Disconnect the Battery

To begin the reset process, you will need to disconnect the battery. Locate the vehicle’s battery, which is usually situated in the engine compartment. First, ensure that the vehicle is turned off and the ignition key is removed. Then, using a wrench or socket set, carefully disconnect the negative terminal of the battery. Leave the battery disconnected for approximately 15-30 minutes. This will allow the vehicle’s electrical circuits to reset completely.

Step 4: Reconnect the Battery

After the allotted time has passed, reconnect the negative terminal of the battery and tighten it securely. Ensure that the connection is snug but not overly tight, as excessive force may damage the battery or components.

Step 5: Start the Vehicle

With the battery reconnected, turn on the ignition and start the vehicle. Allow it to idle for a few minutes to stabilize. During this time, the vehicle’s onboard computer will perform self-diagnostics and may recalibrate various systems, including the emissions control system.

Step 6: Test Drive

Take your Renault for a short test drive, preferably on a mix of urban and highway roads. Pay close attention to any changes in vehicle performance or any recurring warning messages. If the “Check Anti Pollution System” warning no longer appears, it is likely that the reset was successful, and the issue has been resolved. However, if the warning persists or if new issues arise, it is advisable to schedule a professional inspection to identify and address any underlying problems.


Resetting the “Check Anti Pollution System” warning on your Renault is a relatively straightforward process that can save you from unnecessary worry. However, it is essential to diagnose and address the underlying issue before proceeding with the reset. By following the steps outlined in this article and seeking professional assistance if necessary, you can ensure that your Renault continues to provide a smooth and eco-friendly driving experience.
