What Does the Check Engine Light Do?

A check engine is an indicator lamp that lets you know that something is wrong with your engine. Specifically, it illuminates when there is a problem that would impact the vehicle’s emissions. This can be a broad range of problems, primarily ones with the drivetrain or exhaust system. However, the light wouldn’t come on when there is a problem with the headlights, for example.

When the check engine light turns on, it is because the engine control unit has detected a fault. The ECU will store a code then illuminate the light. Because the light is binary (on or off), it is important to check the codes to figure out the problem.

How Do You Check Your Codes?

When you have your check engine light on and need to check the codes, you can use a system called OBD-II (short for on-board diagnostics version two). Every vehicle built after 1996 in the U.S. (and most other countries) has a port that can accept an OBD-II scanner. Using a code reader, you can check what the current diagnostic trouble codes set in the ECU are.

You can easily find OBD-II scanners of different complexities and price points at stores like AutoZone. Additionally, any mechanic you visit will have one and can check the codes for you.

It is worth noting that the code is just the first step in troubleshooting. In many cases, you may need to take a closer look at the system to find the problem. Nonetheless, it will let you know which subsystem is the cause. Trouble codes provide a lot of detail and can help you find a step-by-step troubleshooting and fixing process.

Check out the problem and pick up some parts to help you fix it.
