How to Reset a Check Engine Light

Having trouble with that pesky “Check Engine” light? The check engine light can be an enigma to many Livonia drivers, but luckily, Gordon Chevrolet, Inc. can help you navigate it. Here, we break down “How to reset a check engine light” into simple, user-friendly steps.

Why Does the Check Engine Light Come On?

Your vehicle is a sophisticated machine, and the check engine light is a way for it to communicate potential issues. While the exact cause varies from minor issues like a loose gas cap to more serious ones like malfunctioning spark plugs or emission system problems, the main thing to remember is not to panic.

Reset the Check Engine Light: Guide 

Resetting the check engine light (CEL) can vary from vehicle to vehicle, and the process is usually specific to the make and model of the car. But here is a general step-by-step rundown: 

Method 1: Using an OBD-II Scanner

• Plug an OBD-II scanner into the OBD-II port, usually located under the dashboard.
• Turn on the car’s ignition but don’t start the engine.
• Follow the instructions on the scanner to read the codes. Make note of them so you can address the underlying issue.
• Erase or clear the codes using the scanner’s instructions.
• Unplug the scanner and turn off the ignition.
• Start the engine to see if the light has been reset.

Method 2: Disconnecting the Battery 

If you don’t have an OBD-II scanner, you might try disconnecting the battery, but this method can sometimes cause other issues, like losing settings for the radio, clock, and other systems.

• Turn off the vehicle and remove the keys.
• Open the hood and locate the car’s battery.
• Disconnect the negative battery terminal (usually marked with a “-” sign) by loosening the bolt with a wrench.
• Leave the terminal disconnected for 10-15 minutes.
• Reconnect the terminal and tighten the bolt.
• Start the vehicle and check if the light has been reset.

Please note that this second method doesn’t always work on all vehicles and can lead to unintended consequences, like losing saved settings in your vehicle.

Also, in some cases, if the underlying issue is fixed and it’s not a serious problem, the check engine light might reset itself after several driving cycles.
