Check Engine Light Turns On- An Emission System Problem

If your engine light is on, it typically means the vehicle’s emissions control system is not working correctly, and the vehicle is polluting the atmosphere beyond acceptable standards set by the government. A vehicle in this state would fail a smog check or an emission inspection. In this situation, you must visit any Emission Testing Centre in Ontario to get a proper emission test from qualified technicians.



Don’t confuse the check engine light with the service or maintenance light. These lights lighten when your regular vehicle maintenance service is due. They are generally triggered by mileage, lots of fuel consumed, or some other types of vehicle inspection measurement.

Check Engine Light Turns On

Not all check engine light warnings are responding in the same way. Here are four general situations:

• The check engine light lights up only in some conditions or flickers.

If the check engine light illuminates while driving in the city but goes off on the freeway, then the problem only occurs in city traffic conditions. It also might glint inconsistently. Pay attention to whether or not the vehicle drives any differently when you see the light. If you observe a difference, drive the car as little as possible and bring it to the automobile service center. If you don’t see any variation in vehicle performance, you can drive home but have it checked as quickly as possible. In this condition, you risk the vehicle dying or malfunctioning its components.

• The check engine light brightens and remains on.

If your vehicle’s check engine light regularly illuminates during driving with no noticeable driving or performance issues, there is a permanent defect in the emission control system. When this happens, the computer that regulates the emissions system will normally make it, so your SUV runs only at a low speed- this is known as “limp mode.” You must get the vehicle overhauled as soon as possible.

• The check engine light irradiates, stays on, and there are performance glitches.

This means that an important component of the emission control and engine management system has severe issues. It generally involves an automobile part or mechanism required for the vehicle to run. In several cases, driving a vehicle is not safe at all; it could stop at any moment. It’s good to pull over your mini truck to a safe place and have the vehicle towed to an automobile service center for a full inspection.
