Check Engine Light Basics

Last updated 7 years ago

There are many things that can cause your check engine light to illuminate, and not all of the reasons are apparent to the naked eye. Certain procedures must be followed to determine what in particular is causing your car’s computer to turn on the check engine light.

This video explains how a mechanic goes about determining what is wrong with a vehicle when a check engine light is on. The presenter demonstrates the use of a device that retrieves codes from your car’s computer and allows the mechanic to easily find what part of the engine is causing trouble and must be inspected.
