What is the service engine soon light?

The service engine soon light is a warning light that illuminates on the dashboard of a vehicle to indicate that there is a problem with the engine or its emissions control systems.

When the service engine soon light comes on, it means that there is a problem with the engine or its emissions control systems.

What are the causes of the service engine soon light coming on?

There are many different causes of the service engine soon light coming on. Some of the most common causes include:

* **Misfires:** A misfire occurs when the spark plug does not ignite the fuel in the cylinder. This can cause the engine to run rough and can eventually damage the catalytic converter.
* **Fuel system problems:** Fuel system problems can include a clogged fuel filter, a faulty fuel injector, or a problem with the fuel pump. These problems can cause the engine to run lean or rich, which can damage the engine and its emissions control systems.
* **Emissions control system problems:** Emissions control system problems can include a faulty oxygen sensor, a faulty catalytic converter, or a problem with the evaporative emissions control system. These problems can cause the engine to emit excessive pollutants, which can lead to fines and other penalties.

What should I do if the service engine soon light comes on?

If the service engine soon light comes on, you should take your vehicle to a qualified mechanic as soon as possible to have the problem diagnosed and repaired. Ignoring the service engine soon light can lead to further damage to the engine or its emissions control systems, which can be expensive to repair.
