What Does the Check Engine Light Indicate?

The check engine light warns you of engine or emission system issues. It could be something simple like a loose gas cap or a bigger problem. Cars today have smart systems that give more details when the light comes on.

When the light turns on, check your dashboard for other lights. Also, notice if your car is driving differently. The emissions sensor is key in checking emissions and can turn on the light if it finds a problem.

Common Myths About the Check Engine Light

There are myths about the check engine light that can confuse or worry you. One myth is that it always means a big problem. But, it can also mean a simple fix like tightening a gas cap.

Another myth is driving with the light on is safe. While sometimes it is, it’s best to get it checked by a pro. At Heaven Automotive, we say don’t ignore the light and get it checked to fix the problem.

Top Causes for the Check Engine Light Activation

Knowing why the check engine light turns on is key to keeping your car in good shape. It can light up for many reasons. Finding the main problem is vital for fixing it right.

Faulty Oxygen Sensor

A bad oxygen sensor is a common reason for the check engine light. It checks the exhaust gases’ oxygen levels. This helps the engine computer adjust the air-fuel mix for best performance.

If the sensor goes wrong, the engine might run too rich or lean. This can lower fuel efficiency and harm the catalytic converter.

Check Engine Light Causes

Loose or Damaged Gas Cap

A loose or broken gas cap is another common cause. The gas cap keeps the fuel system tight, stopping fuel vapors from escaping.

If the cap is loose or broken, it can cause the check engine light to turn on. Just tightening or replacing the cap might fix it.

Malfunctioning Catalytic Converter

The catalytic converter is key for reducing harmful emissions. It’s part of the vehicle’s emissions system.

If it fails, the check engine light will turn on. This is often because of clogs or failure. Replacing a bad catalytic converter can be expensive, so it’s important to fix it quickly.

Engine Misfires

Engine misfires happen when the fuel-air mix in the engine’s cylinders doesn’t light up right. This lowers engine performance and can damage parts like the catalytic converter.

The check engine light can light up for misfires. These can be caused by bad spark plugs, ignition coil problems, or fuel system issues.

By knowing these common causes, car owners can start figuring out and fixing the problem that makes the check engine light come on.
