Turn off your Check Engine light

So your Check Engine light is on, staring at you every day. You know there must be something wrong, but you don’t want to pay to have the problem diagnosed. Don’t worry - we’ve got you covered. With a simple code-reader tool, you can find out what’s wrong and turn the light off. When the Check Engine light is on, it means one or more trouble codes are stored in your vehicle’s computer. Trouble codes tell you that a problem was identified in the engine- management system. Reading the stored trouble codes is the first step in diagnosing the problem.
Code readers are inexpensive and simple to use
