Chevy Trax Check Engine Light
Schedule ServiceIf your Chevy Trax's check engine light is on, your first instinct may be to panic. After all, the check engine light is there to alert you early when something under the hood isn't working as it should.
But don't panic just yet!
The check engine light in your Chevy Trax is part of its onboard diagnostics system, which continuously monitors engine performance and emissions. It usually appears as a yellow or amber engine-shaped icon on the dashboard, sometimes accompanied by a message.
The cause can range from minor to more serious, so it's best to have it checked as soon as possible. At Boyd Chevrolet, we're here to help you understand what this light in your Chevy Trax means, why it comes on, and what steps to take next.
Read on to find everything you need to know about this little light and how to address it!
Why Is My Chevy Trax Check Engine Light On?
While the check engine light can be triggered by different issues, certain causes are more common in the Chevy Trax. Here are a few to look out for:
Loose or Damaged Gas Cap
This is one of the most common causes of the check engine light. If the gas cap isn't sealed properly, it can trigger the light.
Faulty Oxygen Sensor
This sensor helps manage fuel efficiency and emissions. When it fails, your engine may not run as efficiently, which causes the light to illuminate.
Worn Spark Plugs or Ignition Coils
These components wear over time and can lead to engine misfires, rough idling, or reduced performance.
Catalytic Converter Issues
This is a more serious issue that can affect performance and emissions if not addressed.
Mass Airflow Sensor Problems
This sensor measures the amount of air entering the engine and helps regulate fuel delivery. When it's not working properly, it'll let you know via the check engine light.
EVAP System or Vacuum Leaks
The Trax uses an Evaporative Emission Control (EVAP) system to control fuel vapors and emissions. A loose hose, a small leak, or a faulty valve can all trigger the engine light.
Chevy Trax Check Engine Light Codes
When your check engine light turns on, your Chevy Trax stores a diagnostic trouble code (DTC). These codes are generated by your vehicle's onboard system and help identify the cause of the issue.
Here are a few common check engine light codes you may see in a Chevy Trax:
P0300
Engine misfire detected
The engine isn't firing properly, often caused by worn spark plugs, ignition coils, or fuel system issues.
P0171
System running too lean
The engine is getting too much air and not enough fuel, which can be caused by a vacuum leak or sensor problem.
P0420
Catalytic converter efficiency issue
Indicates a problem with the catalytic converter that can affect emissions and overall engine performance.
P0442
Small EVAP system leak
Usually related to a minor leak in the emissions system, typically due to something simple like a loose or faulty gas cap.
P0496
EVAP system high purge flow
Usually means there's an issue with the purge valve, allowing too much fuel vapor into the engine.
P0101
Mass airflow sensor performance issue
Indicates the mass airflow sensor isn't reading correctly, which can affect how the engine balances air and fuel.
These are just a few of the most common codes your Chevy Trax may display. Once the code is read, the service team at our Chevy Trax dealer near you can run a full diagnostic to identify the cause and recommend the right fix!

Schedule ServiceHow to Reset a Chevy Trax Check Engine Light
If your Chevy Trax check engine light stays on after the issue has been addressed, there are a few ways to reset it. Keep in mind, the light will return if the underlying problem hasn't been properly fixed.
1
Check and Tighten the Gas Cap
A loose or damaged gas cap is one of the most common reasons the check engine light comes on. Tightening or replacing it may cause the light to turn off after a short drive.
2
Allow the System to Reset Naturally
After a repair is completed, your Trax may clear the code on its own after a few normal driving cycles. This can take a day or two, depending on driving conditions.
3
Disconnect the Battery
Disconnecting the negative battery cable for a short period can reset the vehicle's system and clear stored codes. You can also use this method to reset other vehicle settings.
4
Use an OBD-II Scanner
A diagnostic tool can be used to read and clear the trouble code directly. This is one of the most reliable ways to reset the check engine light once the issue has been resolved.
Why You Shouldn't Ignore the Check Engine Light
If the check engine light comes on but your Chevy seems to be running normally, it can be tempting to ignore the light. This is never a good idea, though. Even if you can't feel something wrong with your vehicle, waiting too long can lead to more serious and costly issues, including:
- Worsening Issues Minor problems, such as a sensor issue or a small leak, can develop into larger engine or system issues if left unaddressed.
- Increased Repair Costs What could have been a simple fix can quickly become more expensive over time if additional components are affected.
- Reduced Fuel Efficiency Engine or emissions issues can cause your Trax to use more fuel than necessary, costing you more at the pump.
- Emission Test Failure An active check engine light can cause your vehicle to fail an emissions test.

Schedule Service OnlineFAQs
Why is my Chevy Trax's check engine light flashing?
A flashing check engine light usually means the problem is more serious, such as an engine misfire. It's best to avoid driving and have your vehicle checked as soon as possible to prevent further damage.
How long can I drive my Chevy Trax with the check engine light on?
If the light is solid and your Trax is running normally, you can usually drive for a short time. However, it's best to have it checked soon. If the light is flashing or the vehicle is running poorly, you should stop driving as soon as possible and schedule service right away.
Will the check engine light turn off on its own in a Chevy Trax?
In some cases, yes. If the issue that triggered the light has been resolved, the system may turn the light off after a few normal driving cycles. However, if the problem persists, the light will remain on or come back on. It's best to have the vehicle checked to make sure the issue is properly addressed.
Is it expensive to fix a check engine light on a Chevy Trax?
It depends on the cause. Some issues, like a loose gas cap or faulty sensor, are relatively inexpensive (under $100), while more serious problems can cost more. Getting a diagnostic scan early can help avoid higher repair costs later on.
