Why Is My Check Engine Light On?

Top Things to Do When Your Check Engine Light Comes On  

• Check for critical warnings: Look at your other dashboard lights and gauges. If oil pressure is low or the engine is overheating, pull over and turn off your vehicle immediately.
• Consult your owner's manual: It will help you understand your vehicle's warning indicators and common causes of check engine alerts.  
• Tighten your gas cap: This is one of the most common and easily fixable issues. It may take a few trips for the light to reset if this was the cause.  
• Reduce stress on your engine: If the light is blinking or your vehicle is running rough, reduce speed and engine load. Stop towing if you're hauling and seek service right away.  
• Read the diagnostic code: If you have a scan tool, you can check the engine code yourself. These are available at most auto parts stores. However, for many drivers, letting a certified technician handle the diagnosis is more efficient and cost-effective. 
• Don't delay service: Even if your car seems to run fine, the check engine light means something needs attention. For fast, affordable diagnostics and repair near Little Rock, contact Gwatney Chevrolet today.

Frequently Asked Questions About Check Engine Lights

What does the check engine light mean?

The check engine light, or "service engine soon" light, is a warning that your vehicle's onboard diagnostic system has detected a problem. It could be a simple issue like a loose gas cap or something more serious like a misfiring engine or a failing sensor.

Is it safe to drive with the check engine light on?

If the light is steady and your vehicle seems to run normally, it's usually safe to drive for a short period. However, you should have it checked soon. If the light is flashing or your car is showing performance issues, reduce speed, pull over safely, and seek service immediately.

What should I check first when the check engine light comes on?

Start by checking your gas cap. A loose or damaged cap is one of the most common reasons for the light to appear. Also, check your dashboard for other warning lights like low oil pressure or overheating.

How can I turn off the check engine light?

If the issue is minor and resolved-like tightening the gas cap-the light may turn off after a few drive cycles. Otherwise, you'll need a scan tool to read and clear the diagnostic trouble code. Our certified technicians at Gwatney Chevrolet can do this quickly and accurately.
