Seeing that warning light glowing on your Chevrolet's dashboard can be worrying. Whether you drive a Chevy truck, car, or SUV, understanding how to reset the check engine light can save you time and stress. However, before attempting to reset it yourself, there are important things you should know.
Things To Consider Before Resetting the Check Engine Light
The check engine light on your Chevy warns you about potential issues with your vehicle. Before you reset it:
-
Check your gas cap: A loose or damaged fuel cap is a common cause of check engine lights in Chevrolet vehicles. Make sure it's tight and not cracked.
-
Consider the actual problem: The light might indicate something minor or a serious issue. This includes things like oxygen sensor failure, catalytic converter issues, spark plug or ignition coil problems, a failing mass airflow sensor, or even just a simple need for an oil change. But if your Chevy is running strangely, making unusual noises, or showing other warning signs, resetting the light without fixing the problem could lead to damage.
-
Use a code reader: Before resetting, it's helpful to know what triggered the light. Most auto parts stores often offer free code-reading services, or you can purchase an OBD-II scanner to read the codes yourself.
Resetting the Check Engine Light on Your Chevy
If you've addressed the underlying issue or confirmed there's no serious problem, here's how to reset the check engine light on your Chevrolet.
Method 1: Use an OBD-II Scanner
-
Purchase or borrow an OBD-II scanner compatible with Chevrolet vehicles. Alternatively, seek help from a Chevrolet service center.
-
Locate the diagnostic port under your dashboard (usually near the steering column).
-
Plug in the scanner and turn on your Chevy's ignition without starting the engine.
-
Follow the scanner's instructions to read and clear the codes.
-
Turn off the ignition and remove the scanner.
-
Start your vehicle to check if the light has reset.
Method 2: Disconnect the Battery
-
Turn off your Chevy and open the hood.
-
Locate the battery and disconnect the negative cable (usually black with a "-" symbol).
-
Wait about 15 minutes for the car's computer to reset.
-
Reconnect the negative battery cable.
-
Start your Chevy and check if the light is gone.
Method 3: Drive Cycle Reset
Sometimes, your Chevy's computer will reset the light automatically after a certain number of driving cycles if the problem doesn't reoccur:
-
Fix the underlying issue.
-
Drive your Chevrolet normally for several days.
-
The computer may turn off the light after determining the problem is resolved.
