Check Engine Light On Dashboard: Causes and What to do Next article content
The check engine light is usually a yellow or amber engine-shaped warning light on your dashboard that comes on when your car’s onboard computer detects a problem with one of its systems.
Common Causes of the Check Engine Light
A check engine light can come on for several reasons or from a small issue that needs immediate attention. Common reasons why a check engine light comes on may include:
Loose or faulty fuel cap: A loose cap triggers the warning light because it affects the fuel system’s pressure.
Faulty oxygen sensor: This affects your car’s fuel efficiency and emissions.
Bad spark plugs or ignition coils: They cause misfiring, rough idling or loss of power.
Faulty mass airflow sensor: The sensor monitors the amount of air entering your engine.
Catalytic converter damage: A failing catalytic converter can affect engine performance and emissions.
Battery or charging damage: Electrical failure sometimes triggers dashboard warning lights.
Engine or transmission breakdown: More serious mechanical issues can also activate the warning.
That is why guessing the problem from the dashboard light alone is not enough. Your car needs a proper car diagnostics to identify the fault code and determine what is actually happening.
What To Do When the Check Engine Light Comes On
First, check whether the light is steady or blinking.
A steady check engine light usually means you should have the vehicle inspected soon. You may be able to continue driving, but don’t ignore it for weeks and hope the light gets tired and disappears.
If the light is blinking, take it more seriously. A flashing engine warning light indicates an alarming problem and further damage if you keep driving.
If your car is also shaking, losing power, overheating, producing unusual smoke or making strange noises, or showing a red light, find a safe place to stop and get professional help.
Frequently Asked Questions (FAQ)
1. What should I do when my check engine light comes on?
Check that your fuel cap is properly tightened and pay attention to how your car is behaving. If the light stays on, get the car properly diagnosed to find the actual cause.
2. How urgent is a check engine light?
It depends on how the light appears. A steady light with no other symptoms usually means your car needs a diagnostic check soon. A flashing light, especially with shaking, loss of power, overheating or unusual noises, requires more urgent attention.
3. Can I drive with the check engine light on?
If the light is steady and your car is still moving, you can drive to a mechanic or order for a diagnostic service on Whipcare. Avoid unnecessary trips until the problem is identified.
