Imagine you are driving, and a glowing engine symbol suddenly appears on your car's dashboard. The first question that probably comes to mind is, “What does this symbol mean?” This symbol is known as the engine warning light or check engine light. The light can be yellow, orange or amber (depending on your car), and it indicates that there could be a problem with your car’s engine that needs attention. Therefore, understanding the engine symbol is crucial.
What does a check engine light mean and where is it located?
The engine light or symbol usually indicates that there is an issue with the engine and you need to fix it. It is also known as a malfunction indicator lamp. The issue can be a small one, just like a glitch in the gas cap, or it can be something serious, like a misfiring engine. The check engine light symbol shows up on the vehicle’s dashboard or the instrumental panel on all four-wheeler vehicles.
Common reasons why the engine symbol lights up
The engine symbol on your dashboard can appear for many reasons, such as:
- Some defects in the catalytic converter
- Fault in the sensor due to mass airflow
- Defective oxygen sensor
- Open or loose fuel cap
- Malfunction in the thermostat
- Old and damaged spark plug
- Flawed fuel injector
- Reprogram the powertrain control module
Types of engine warning light behaviour
If the system detects an issue, the engine light will turn on in one of two ways:
- Solid engine light: A steady light indicates a minor problem, often related to emissions or safety systems. While it’s not an emergency, it’s a sign that your car needs attention soon.
- Flashing engine light: If the engine light blinks, it signals a serious problem with critical components, such as the engine, fuel system or air intake. In this case, it’s crucial to stop driving and seek professional mechanical help immediately.
How to prevent engine light issues in the future?
Regular maintenance is an important step in avoiding engine light issues. Keeping up with oil changes, tune-ups and routine inspections ensures your vehicle stays in good condition, which reduces the chances of problems developing.
Despite these precautions, the engine light may still appear. When it does, addressing it promptly is crucial because ignoring it can allow a small issue to become a costly repair. For added control, an OBD2 scanner allows you to identify and resolve potential problems early.
Additionally, investing in comprehensive car insurance online can provide peace of mind, covering unexpected repairs or damages and ensuring that you are financially protected in case of unforeseen events. If you need help choosing a plan, simply fill out the form on this page.
