Before you reset the check engine light, it’s crucial to understand what it’s trying to tell you. The check engine light—also known as the malfunction indicator lamp (MIL)—is part of your vehicle’s onboard diagnostics system (OBD2). When it illuminates, it means the computer has detected a problem with the engine, transmission, emissions system, or related components.
On a 2014 Chevy Traverse, the light can come on for a wide range of reasons, from something as simple as a loose gas cap to more serious issues like a failing oxygen sensor or catalytic converter. The light may appear as a steady glow or flash. A flashing light indicates a severe problem that requires immediate attention, while a steady light usually means the issue is less urgent—but still needs to be addressed.
Ignoring the check engine light can lead to reduced fuel efficiency, increased emissions, and even engine damage over time. That’s why it’s important to diagnose the problem before resetting the light. Resetting it without fixing the issue is like turning off a smoke alarm while the fire is still burning—it doesn’t solve the problem.
Why You Shouldn’t Just Reset the Light Without Diagnosis
Many drivers make the mistake of resetting the check engine light as soon as it comes on, hoping it will stay off. But this is a risky approach. The light is there for a reason. If you clear it without addressing the root cause, the problem will likely persist—and the light will return.
For example, if your Traverse has a faulty oxygen sensor, resetting the light won’t fix the sensor. The computer will continue to monitor the sensor’s performance, and once it detects the same issue again, the light will come back on. Worse, driving with a bad oxygen sensor can reduce fuel economy by up to 40% and increase harmful emissions.
Additionally, some issues—like a misfiring engine or a failing catalytic converter—can cause long-term damage if left unchecked. Resetting the light gives you a false sense of security and delays necessary repairs.
So, before you reset the check engine light, take the time to diagnose the problem. Use an OBD2 scanner to read the trouble codes, or visit a trusted mechanic if you’re unsure. Once the issue is fixed, then—and only then—should you reset the light.
Tools You’ll Need to Reset the Check Engine Light
To reset the check engine light on your 2014 Chevy Traverse, you’ll need a few basic tools. The most effective method uses an OBD2 scanner, but there are alternative approaches if you don’t have one.
Here’s what you’ll need:
- OBD2 Scanner: This is the best tool for reading and clearing trouble codes. Most modern scanners are affordable and easy to use. Look for one that’s compatible with GM vehicles and supports OBD2 protocols.
- Owner’s Manual: Your Traverse’s manual contains valuable information about the check engine light, fuse locations, and battery disconnection procedures.
- Basic Hand Tools: If you plan to disconnect the battery, you’ll need a wrench or socket set to remove the negative terminal.
- Pen and Paper: Keep a record of the trouble codes you read and any repairs you make. This helps track your vehicle’s history.
If you don’t own an OBD2 scanner, you can purchase one online for as little as $20–$50. Many auto parts stores also offer free code reading services, so you can get the diagnostic information without buying a scanner.
Method 1: Using an OBD2 Scanner (Recommended)
The most reliable and accurate way to reset the check engine light on your 2014 Chevy Traverse is by using an OBD2 scanner. This method allows you to read the trouble codes, understand what’s causing the light, and safely clear it after repairs.
Step 1: Locate the OBD2 Port
The OBD2 port on your 2014 Chevy Traverse is located under the dashboard, near the driver’s side footwell. It’s usually a 16-pin connector, shaped like a trapezoid, and may be covered by a small plastic panel. To access it, simply reach under the steering column and look for the port.
If you’re having trouble finding it, consult your owner’s manual or look for a diagram online. The port is standard across all OBD2-compliant vehicles, so it should be easy to identify.
Step 2: Plug in the OBD2 Scanner
Turn off the ignition, then plug the OBD2 scanner into the port. Make sure the connection is secure. Some scanners have a power button, while others turn on automatically when plugged in.
Once connected, turn the ignition to the “ON” position (but don’t start the engine). This powers up the vehicle’s computer and allows the scanner to communicate with it.
Step 3: Read the Trouble Codes
Follow the scanner’s on-screen instructions to read the trouble codes. Most scanners will display a list of codes, such as P0420 (catalytic converter efficiency below threshold) or P0171 (system too lean).
Write down each code and refer to the scanner’s manual or an online database to understand what it means. This information will help you determine what repairs are needed.
For example, a P0442 code often indicates a small leak in the evaporative emissions system, which could be caused by a loose or damaged gas cap. Tightening or replacing the cap may resolve the issue.
Step 4: Repair the Issue
Once you’ve identified the problem, make the necessary repairs. This could involve replacing a sensor, fixing a vacuum leak, or tightening the gas cap.
If you’re not comfortable making the repair yourself, take your Traverse to a qualified mechanic. Be sure to provide them with the trouble codes so they can diagnose the issue accurately.
Step 5: Clear the Codes and Reset the Light
After the repair is complete, return to the OBD2 scanner and select the option to “Clear Codes” or “Reset MIL.” The scanner will send a command to the vehicle’s computer to turn off the check engine light.
Once the codes are cleared, the light should go off. If it doesn’t, double-check the scanner’s connection and try again. Some scanners may require you to turn the ignition off and on after clearing.
Step 6: Complete a Drive Cycle
After resetting the light, it’s important to complete a drive cycle. This allows the vehicle’s computer to recheck all systems and confirm that the issue has been resolved.
A typical drive cycle for a 2014 Chevy Traverse includes:
- Start the engine and let it idle for 2–3 minutes.
- Drive at 30–40 mph for 5–10 minutes.
- Accelerate to 55–60 mph and maintain speed for several minutes.
- Decelerate and come to a complete stop.
- Repeat the cycle once or twice.
During this process, the computer will run self-tests on the emissions system, oxygen sensors, and other components. If no new trouble codes are detected, the check engine light should remain off.
Method 2: Disconnecting the Battery (Alternative Method)
If you don’t have an OBD2 scanner, you can try resetting the check engine light by disconnecting the battery. This method forces the vehicle’s computer to reset, which may clear the light—but it’s not as reliable as using a scanner.
Step 1: Turn Off the Engine and Remove the Key
Make sure the engine is off and the key is removed from the ignition. This prevents any electrical surges or damage during the process.
Step 2: Locate the Battery
The battery on a 2014 Chevy Traverse is located in the engine compartment, on the driver’s side. It’s housed in a black plastic case with positive (+) and negative (-) terminals.
Step 3: Disconnect the Negative Terminal
Using a wrench or socket set, loosen the nut on the negative (-) battery terminal. Carefully remove the cable and set it aside, making sure it doesn’t touch the terminal or any metal parts.
Wait at least 15–30 minutes. This allows the vehicle’s computer to fully power down and reset.
Step 4: Reconnect the Battery
After waiting, reattach the negative cable to the battery terminal and tighten the nut securely. Make sure the connection is tight to prevent electrical issues.
Step 5: Start the Engine
Turn the ignition to the “ON” position and wait a few seconds. Then start the engine. The check engine light may flash briefly, then turn off.
Note: Disconnecting the battery can reset other systems, such as the radio presets, clock, and adaptive transmission settings. You may need to reprogram these features after reconnecting.
Also, this method doesn’t guarantee the light will stay off. If the underlying issue isn’t fixed, the light will likely return after a few drive cycles.
Method 3: Drive Cycle Reset (Natural Reset)
In some cases, the check engine light may turn off on its own after the issue is resolved—especially if it was triggered by a temporary condition, like a loose gas cap.
This is known as a “natural reset” and occurs when the vehicle’s computer runs a drive cycle and confirms that all systems are functioning properly.
To encourage a natural reset:
- Ensure the gas cap is tight and properly sealed.
- Drive the vehicle normally for several days, including highway and city driving.
- Avoid short trips—longer drives help the computer complete its self-tests.
If the light turns off after a few days of driving, the issue may have been minor and resolved itself. However, if the light returns, it’s time to diagnose the problem properly.
Common Causes of Check Engine Light on 2014 Chevy Traverse
Understanding why the check engine light comes on can help you prevent future issues. Here are some of the most common causes on the 2014 Chevy Traverse:
- Loose or Faulty Gas Cap: This is the #1 cause of check engine lights. A loose cap allows fuel vapors to escape, triggering an evaporative emissions code.
- Oxygen Sensor Failure: The Traverse has multiple oxygen sensors that monitor exhaust gases. A faulty sensor can reduce fuel efficiency and increase emissions.
- Mass Airflow Sensor (MAF) Issues: The MAF sensor measures incoming air. If it’s dirty or malfunctioning, it can cause poor performance and trigger the light.
- Catalytic Converter Problems: A failing converter can trigger codes like P0420. This is often due to long-term engine issues or poor fuel quality.
- Spark Plug or Ignition Coil Failure: Misfires can damage the catalytic converter and trigger codes like P0300.
- Evaporative Emissions System Leaks: Small leaks in the EVAP system can cause codes like P0442 or P0455.
Regular maintenance—such as changing spark plugs every 100,000 miles, replacing the air filter, and using quality fuel—can help prevent many of these issues.
Troubleshooting Tips
If you’ve reset the check engine light but it keeps coming back, here are some troubleshooting tips:
- Double-check repairs: Make sure the issue was fully resolved. For example, if you replaced a sensor, verify it’s the correct part and installed properly.
- Clear codes after repairs: Always use an OBD2 scanner to clear codes after fixing the problem. Don’t rely on battery disconnection alone.
- Monitor driving habits: Aggressive driving, short trips, and low fuel levels can trigger the light. Drive smoothly and keep the tank above 1/4 full.
- Check for software updates: Sometimes, a software update from a dealership can fix computer-related issues.
- Visit a mechanic: If the light persists, have a professional diagnose the issue. They have advanced tools and experience with GM vehicles.
