Loose Gas Cap

This is a common and easiest issue to solve. Simply tightening the gas cap on your car will solve the issue. So, when the check engine light comes on, before doing anything, first check the gas cap of your Chevy Traverse.

Malfunctioning Fuel Injection System

The main problems that cause the check engine light on the fuel injection system are clogged injectors and problematic fuel pumps. In this case, you will have to replace the injector or fuel pump.

Dirty Mass Airflow Sensor

This is another cause for the check engine light on the Chevy Traverse. A dirty mass airflow sensor interrupts the air-fuel mixture. So, this results in triggering the check engine light. You may need the help of a professional to check the mass airflow sensor.

The Damaged Emissions Control Part

A damaged component of the emissions control system, such as the catalytic converter or oxygen sensor, can cause the check engine light to turn on.

A problematic catalytic converter or oxygen sensor in the emission control system causes the check engine light on the Chevy Traverse. You need to check them out and repair them before or after resetting the check engine light.

Damaged Head Gasket

The head gasket of the Chevy Traverse is found between the engine block and the cylinder head. This tiny yet essential component seals the internal combustion process. This enables coolant and oil to circulate throughout the engine to cool and lubricate it. If the gasket is damaged, coolant and oil are mixed. This results in engine overheating and check engine light.

Old Spark Plugs

Spark plugs are worn out when they become old. Worn-out spark plugs result in engine misfires and reduced fuel efficiency.

How To Reset Check Engine Light Chevy Traverse?

Now you know why the check engine light comes on in Chevy Traverse. So, how to reset check engine light on Chevy Traverse? You need an OBD2 scanner for this task. If you currently don’t have a scanner, you have to borrow or buy one.

What Are the Things You Should Know Before Buying an OBD2 Scanner?

Are you going to buy an OBD2 scanner? Here are the 6 main things you should consider when buying:

Tool Capability

Ensure that the scanner covers the specific systems you want to diagnose. Check if it covers the engine, ABS, airbag, or other systems you’re interested in.


Consider your budget and the level of functionality you need. If you only need to diagnose a check engine light, a cheaper tool will be enough.

Updates and Update Costs

Free updates allow you to access the latest software and add support for newer vehicles. Find out if the scanner provides free updates. If not, you need to pay extra money for them. Tools under a certain price range offer free updates. For other tools, we have to buy a subscription.

Realistic Expectations

Understand that an OBD2 scanner is not a magic fix for all car problems. You can only clear certain warning lights with an OBD2 scanner. Then you should address the underlying issues. If not, the check engine light will come on again after a few days.

Working with Mechanics

If you diagnose a fault yourself, don’t assume that mechanics will solely rely on your findings. They might use their equipment to verify and diagnose the problem. These tools are more effective for personal diagnosis and repair attempts.

Trusted Manufacturers

Stick to reputable manufacturers and software developers.
