Contamination warning light: action and meaning

The anti-pollution warning light is identical to the engine warning light: it is an engine icon and illuminates yellow in the instrument panel. It has three different ignition modes to suit different situations. But it always warns you of a malfunction that affects your pollutant emissions.

🔍 What is a pollution indicator light?

there is no pollution protection indicator As a matter of fact: in fact, it is the same light as the headlight of the engine. Hence, he is a seer yellowwhich represents the engine. It has a peculiarity in that it can flash or remain on, as well as periodically light up: these different modes matter. Pollution protection light three different ignition modes.

When the anti-pollution warning light is on, it indicates a malfunction in the engine. The illumination of this warning light is controlled by a diagnostic system controlled by the device. EOBD (European On-Board Diagnostics) and the system OBD (On-board diagnostics) is an American system.

These two systems meet the requirements of the pollution control standards. Today it Standard Euro 6... These standards are aimed at controlling the emission of pollutants into the atmosphere from cars in order to reduce the pollution of the environment from cars.

Among the components in your vehicle that are included in the EOBD system and which can trigger the anti-pollution warning light in the event of a malfunction are, in particular, exhaust system parts (catalytic converter, particulate filter, etc.) related to combustion (TDC sensor , temperature sensor) and all parts that affect emission control.

💡 Why does the anti-pollution indicator light up?

The anti-pollution warning light comes on when one of the parts affecting the control or emission of pollutants in your vehicle: the TDC sensor, the catalytic converter or even the particulate filter. It may be accompanied by a message indicating the nature of the problem or a “pollution anomaly”.

The anti-pollution indicator light has three different operating modes:

• It turns on for a moment and then turns off : This is a small defect that does not have a long-term effect on the level of pollutant emissions.
• Contamination protection indicator flashes : This is a malfunction that can damage or even destroy the catalytic converter.
• The anti-pollution indicator remains on. : the problem constantly affects the level of pollutant emissions.

If the anti-pollution warning light comes on, the engine may go into reduced performance mode. You will also experience loss of power and other symptoms associated with the failure of the part responsible for the failure.

🚗 Can I drive with the pollution warning lamp lit?

It is possible to drive with the anti-pollution warning light on, especially if it comes on intermittently during this operating mode. However, we do not recommend continuing to drive when the anti-pollution warning light comes on, regardless of the ignition mode.

Indeed, a lit anti-pollution indicator not only indicates increased emissions of pollutants your car, but also a problem that could cause you degraded engine and / or damage it. The part responsible for turning on the warning light can also be irreparably damaged.

In short, continuing to drive with the pollution warning lamp on can damage your engine or one of its components and result in a costly bill.

👨‍🔧 How to remove the light to protect against pollution?

If the anti-pollution lamp is on, go to the garage. If the light stays on, the problem is serious and you should contact a mechanic immediately because the engine will go into reduced performance mode to protect it and prevent damage.

The mechanic will conductself-diagnosis to understand the nature of the problem, then repair the part causing the anti-pollution warning light to illuminate. It is likely that it will be required change the room discussed. This will turn off the anti-pollution warning light and return your vehicle to normal operation.

That's it, you know how the anti-pollution indicator light works! As you already understood, this is a warning light that warns you of a problem with one of the parts of your car. Do not continue driving like this and consult one of our trusted mechanics.
