What is check engine light?

The check engine light, also known as the malfunction indicator lamp (MIL), is a warning light on the instrument panel of a vehicle that indicates a problem with the engine or emissions control system. It is typically illuminated when the vehicle's on-board diagnostics (OBD) system detects a fault or malfunction in any of the vehicle's systems.

Here are some common causes of the check engine light coming on:

>* Loose or faulty gas cap

>* Faulty oxygen sensor

>* Catalytic converter problems

>* Engine misfires

>* Problems with the emissions control system

>* Faulty spark plugs or ignition coils

>* Vacuum leaks

>* Faulty fuel injectors

>* Coolant temperature sensor problems

>* Mass airflow sensor (MAF) problems

When the check engine light comes on, it is important to have the vehicle diagnosed by a qualified mechanic to determine the cause of the problem and have it repaired as soon as possible. Ignoring the check engine light can lead to more serious problems and expensive repairs in the future.
