Many factors can trigger the illumination of the engine emission warning light. Some common reasons include carbon buildup in the catalytic converter, exhaust system malfunctions, fuel pump or ignition system failures, among others. If these issues are not addressed promptly, they may cause greater damage to the vehicle and even pose a risk to the safety of the driver and others.
If the engine emission warning light comes on and the vehicle can still be driven, but experiences shaking, lack of acceleration, or other issues, it is advisable to pull over and park the vehicle as soon as possible. Seek the assistance of a professional mechanic for inspection. It is not advisable to continue driving, as safety always comes first.
Additionally, emission issues with the engine are crucial for the vehicle's annual inspection. Therefore, it is important to address these problems promptly to avoid affecting normal vehicle use and passing the annual inspection.
When the engine exhaust system malfunction light illuminates, it is recommended to call for roadside assistance and have the vehicle towed to a repair facility. Even though the vehicle may still be able to drive normally, the emission of exhaust gases may become heavier, internal engine wear may intensify, and fuel consumption may noticeably increase.
The reasons for engine emission system failures may include subpar gasoline quality, leading to poisoning of the catalytic converter or sensor malfunctions. Therefore, upon discovering an engine malfunction, it is best to visit a repair shop for inspection immediately. Additionally, simple methods can be tried to determine if a genuine malfunction exists, such as performing three consecutive start and stop cycles or disconnecting the battery's negative terminal for 30 seconds before reconnecting it. These methods can help assess whether a real fault is present.
