When the dreaded “Check Engine Light” appears on your dashboard, it can trigger anxiety and uncertainty among car owners. This warning indicator is designed to alert drivers about potential issues with their vehicle, but decoding its message can often be confusing. In this comprehensive guide, we will delve into the causes of the Check Engine Light, its importance, and the necessary steps to address it effectively.
What Triggers the Check Engine Light?
The Check Engine Light can illuminate for a multitude of reasons, including:
- Oxygen Sensor Malfunction: An oxygen sensor measures the amount of unburned oxygen in a vehicle’s exhaust system. If it fails, your car’s fuel efficiency may be compromised.
