Anti-Pollution Fault: Can You Still Drive Your Peugeot 207?

The anti-pollution fault is a common issue with the Peugeot 207, affecting vehicles built between 2007 and 2015 with standard 1.4 and 1.6-litre engines and higher-powered VTi and GT CC versions. This warning message can be caused by various factors, including issues with the ECU, head gasket, fuel/air ratio, fuel quality, spark plugs, exhaust system, and air management. While the car can still be driven, it is recommended to get it checked by a professional to identify the specific cause and resolve the issue.

The ECU and head gasket are often the cause of the anti-pollution fault in the Peugeot 207

The Peugeot 207 is a popular car model, but it is not without its faults. One issue that has been known to affect these vehicles is the appearance of an 'anti-pollution fault' message on the information display in the instrument cluster. This fault often stems from issues with the ECU (engine control unit) or the head gasket.

The ECU in the Peugeot 207 is prone to failure, and this can trigger the 'anti-pollution fault' message. A faulty ECU can cause a range of problems, including a constant overheating warning light, a constantly running coolant fan, and engine idling and misfire issues. The failure of the coolant temperature sensor or gauge can also lead to the anti-pollution fault message being displayed.

Another common cause of the anti-pollution fault in the Peugeot 207 is a faulty head gasket. This can lead to a loss of coolant without any visible external leaks. The incorrect fuel/air ratio caused by a faulty head gasket can trigger the anti-pollution fault, as the second sensor in the exhaust detects this issue.

In addition to ECU and head gasket problems, there are other factors that can contribute to the anti-pollution fault in the Peugeot 207. These include low-quality or incorrect fuel types, worn spark plugs, blocked or damaged exhaust system components, and malfunctioning air sensors or dirty air filters.

While the anti-pollution fault in the Peugeot 207 can be worrying, it is a fixable problem. Experts in remanufacturing and instrument cluster repairs can help get your car back on the road. Remanufacturing involves restoring used or worn-out products to a condition that meets or exceeds their original specifications, providing an environmentally friendly and sustainable solution.

The anti-pollution fault can also be caused by an incorrect fuel-to-air ratio, leading to engine misfire

The Peugeot 207 is a popular car model, but like any vehicle, it has its issues. One common problem is the appearance of an 'Anti-Pollution Fault' message on the information display. This issue affects Peugeot models built between 2000 and 2014, and while it can be worrying, there are solutions available.

The anti-pollution fault in the Peugeot 207 is often caused by issues with the ECU or the head gasket. However, in the 1.4 or 1.6 VTI models without a turbo, the fault is triggered by an incorrect fuel-to-air ratio, which can lead to engine misfire. This means that there is too much air and not enough fuel in the mixture, resulting in incomplete combustion. This, in turn, leads to increased emissions, which trigger the anti-pollution fault.

An incorrect fuel-to-air ratio can cause the engine to run rich, which has several consequences. Firstly, it can cause the engine oil to turn black due to unburned fuel passing through the piston rings and being absorbed by the crankcase oil. This can be identified by a "Check Engine" light on the dashboard. Additionally, the increased emissions can lead to the anti-pollution fault, as the car's systems detect higher levels of unburned fuel in the exhaust.

There are several potential causes of an incorrect fuel-to-air ratio. One possibility is a problem with the air intake system, where a sensor malfunction or a dirty air filter can disrupt the air-fuel ratio. Another cause could be related to the fuel system, where low fuel intake due to component issues results in an incorrect ratio. Exhaust system issues, such as leaks or faulty sensors, can also contribute to the problem.

To address an incorrect fuel-to-air ratio, several corrective actions can be taken. One suggestion is to use a fuel system or injector cleaner additive and ensure that the air filter is clean and the fuel cap is secure. Extended motorway driving can also help clear the pipes. In some cases, the issue may be as simple as a loose connection or corrosion, especially if the problem occurs after heavy rain, as water ingress can be a factor.

Faulty ignition coils can cause the anti-pollution fault, and they are a straightforward repair

If you're experiencing an anti-pollution fault in your Peugeot 207, don't panic. This issue is not uncommon and can be fixed. One potential cause is faulty ignition coils, which is good news because they are straightforward to repair.

The ignition coil is responsible for providing the spark that ignites the fuel in the engine, and when it's not working properly, it can cause a range of issues, including the anti-pollution fault. The good news is that ignition coils are relatively easy and inexpensive to replace. In some cases, you may only need to replace one coil, not all of them.

If you're handy with cars, you can replace the ignition coil yourself. It's a simple process that just requires a few tools and some basic knowledge of car maintenance. However, if you're not comfortable doing it yourself, it's best to take your car to a trusted mechanic or garage. They will be able to diagnose the issue and replace the ignition coil if needed.

To prevent future issues, it's important to maintain your Peugeot 207 according to the manufacturer's recommendations. This includes regular oil changes, spark plug replacements, and other routine maintenance. Additionally, using a higher-quality fuel and fuel additive can help keep your engine running smoothly and prevent issues like the anti-pollution fault.

While the anti-pollution fault can be frustrating, it's important to address it promptly. Driving with this fault can cause further damage to your car, and it's also not ideal for the environment due to increased emissions. So, whether you choose to fix it yourself or take it to a professional, don't ignore the issue. Get it fixed, and your Peugeot 207 will be back on the road in no time!

Water ingress can cause the anti-pollution fault, especially after heavy rain

Water ingress can cause the anti-pollution fault in a Peugeot 207, especially after heavy rain. Water ingress occurs when water from the outside finds its way into the structure of the car. Heavy rain can cause water to enter the car through cracks, porous building materials, or other vulnerabilities.

In the case of the Peugeot 207, water ingress can affect the ECU (Engine Control Unit) and BSI connectors. The ECU is particularly sensitive and delicate, and water ingress can cause a variety of issues, including the anti-pollution fault. It is important to inspect the ECU and BSI connectors for any signs of moisture or oxidation, as this can indicate water ingress.

To prevent water ingress, it is recommended to inspect the car regularly for any cracks or vulnerabilities that could allow water to enter. Sealing these areas with waterproof materials can help to prevent water ingress and the associated issues.

If water ingress has occurred, it is important to act quickly to address the problem.

The anti-pollution fault can be caused by a faulty lambda sensor circuit, leading to MOT emissions failure

The Peugeot 207 is a popular car model that has been in production since 2007. However, some owners of this vehicle have reported issues with the "anti-pollution fault" message appearing on their dashboard. This issue is not uncommon and can be caused by a variety of factors, one of which is a faulty lambda sensor circuit.

The lambda sensor, also known as the oxygen sensor, plays a crucial role in ensuring the car's engine burns the correct mixture of air and fuel. It is located in the car exhaust, between the exhaust manifold and the catalytic converter. When the lambda sensor is faulty, it fails to send the necessary data to the car's Electronic Control Unit (ECU), which then uses faulty information, leading to increased fuel consumption and higher polluting emissions.

In the case of the Peugeot 207, a faulty lambda sensor circuit can result in MOT emissions failure. This is because the lambda sensor is responsible for ensuring the car complies with European regulations on pollution and CO2 emissions. When the sensor malfunctions, it can cause the catalytic converter to become clogged, leading to a failure during emissions testing.

There are several symptoms that may indicate a faulty lambda sensor. These include the engine warning light illuminating on the dashboard, jerking or shaking while the car is in park, unusually high fuel consumption, and low engine power during acceleration. If you notice any of these issues, it is recommended to consult a mechanic, who can diagnose the problem using a car diagnostic tool.

It is important to address a faulty lambda sensor as soon as possible. Driving without a functioning lambda sensor is not advisable, as it can lead to increased fuel consumption and higher emissions, which are not only harmful to the environment but may also result in costly repairs due to clogged catalytic converters.
