How to Reset Anti Pollution Fault Peugeot 207 – A Step-by-Step Guide


Peugeot 207 is a popular compact car known for its efficient performance and stylish design. However, like any other vehicle, it can encounter issues over time. One issue that may arise is the “Anti Pollution Fault” error message. This error indicates that the vehicle’s pollution control system is experiencing a problem. While it is advisable to diagnose and fix the underlying issue causing this fault, in some cases, a simple reset procedure can resolve the problem. In this article, we will guide you on how to reset the Anti Pollution Fault in your Peugeot 207.

Step 1: Preparation

Before attempting to reset the Anti Pollution Fault, it’s important to ensure your vehicle is parked in a safe location and the engine is turned off. Additionally, make sure you have a reliable OBD-II (On-Board Diagnostic) scanner or the necessary tools to perform the reset procedure.

Step 2: Locate the OBD-II Port

Next, you need to locate the OBD-II port in your Peugeot 207. This port is typically found underneath the dashboard, on the driver’s side. It is a small rectangular connector with 16 pins. Once you have located the port, you’ll be ready to connect the OBD-II scanner.

Step 3: Connect the OBD-II Scanner

Connect your OBD-II scanner to the OBD-II port in your Peugeot 207. Ensure that the connector is securely plugged in. The scanner will establish a connection with the vehicle’s computer system, allowing you to retrieve fault codes and perform diagnostics.

Step 4: Retrieve Fault Codes

Once the OBD-II scanner is connected, turn on the ignition without starting the engine. The scanner will power on and display various options on its screen. Select the “Read Codes” or similar function to retrieve the fault codes stored in the vehicle’s computer. These fault codes will provide insight into the underlying cause of the Anti Pollution Fault.

Step 5: Diagnose the Issue (Optional)

If you have retrieved the fault codes, it is advisable to diagnose and fix the underlying issue before proceeding with the reset procedure. The fault codes will indicate specific areas or components that require attention, helping you pinpoint the problem more accurately. Additionally, resolving the underlying issue will prevent the error message from reoccurring in the future.

Step 6: Clear the Fault Codes

If you have diagnosed and resolved the underlying issue or choose to proceed with the reset procedure without diagnosis, it’s time to clear the fault codes. Using your OBD-II scanner, select the “Clear Codes” or similar function to erase the stored fault codes in the vehicle’s computer system. This action resets the system, including the Anti Pollution Fault message.

Step 7: Restart the Vehicle

After successfully clearing the fault codes, turn off the ignition and disconnect the OBD-II scanner. Wait for a few minutes before turning on the ignition again. Start the engine and observe if the Anti Pollution Fault message reappears. In most cases, the message should be gone, indicating a successful reset.

Step 8: Test Drive and Monitor

Take your Peugeot 207 for a test drive to ensure that the reset procedure was successful and that the Anti Pollution Fault message does not reappear. Monitor the vehicle’s performance during the drive, paying attention to any abnormal signs or symptoms. If the message persists or other issues arise, it is recommended to seek professional assistance and have your vehicle thoroughly inspected.


Resetting the Anti Pollution Fault in your Peugeot 207 can be a simple procedure that may resolve the error message. However, it is important to keep in mind that a reset is not always a permanent solution. It serves as a temporary fix, allowing you time to diagnose and address the underlying issue. If the fault messages persist or other problems arise, consult a qualified mechanic or a Peugeot service center for a thorough examination and proper repair.

Remember, regular maintenance, timely repairs, and attentive driving habits are key to keeping your Peugeot 207 in optimal condition and preventing potential issues.
