Q
why did my check engine light turn on
I'm a seasoned industrial engineer with a keen interest in machine learning. Here to share insights on latest industry trends.
There could be several reasons for this:
1. Malfunctioning sensor: Cars have multiple sensors that may trigger the check engine light, including those that measure emissions, airflow, fuel ratio, and others.
2. Spark plugs or wires need replacing: These are integral parts of the vehicle ignition system. If they malfunction, they can cause the engine light to come on.
3. Oxygen sensor needs to be replaced: This sensor measures the amount of unburned oxygen in your car's exhaust system.
4. A loose or broken gas cap: This can cause fuel to evaporate, leading to decreased fuel efficiency and increased emissions, which can turn on the check engine light.
5. Catalytic converter needs replacing: A damaged catalytic converter won't break down exhaust as properly, leading to harmful emissions.
6. Issues with the battery or alternator.
7. There's a problem with the car's fuel system.
8. Issues with the vacuum system.
However, to accurately know why your check engine light is on, you'll need to either have a diagnostic trouble code retrieval tool, or you'll need to take the car to a mechanic.
