The check engine light is a significant feature in your vehicle's dashboard that should never be ignored. When it illuminates, it's your vehicle's way of telling you that something is wrong under the hood. But don't panic, in this month's blog post we explore what it means, potential causes, and how to handle it effectively.
What Does the Check Engine Light Indicate?
The check engine light is part of your vehicle's onboard diagnostics system (OBD). When the OBD detects an issue within your vehicle's engine, transmission, or emission system, it triggers the light. While some problems are minor, others may require immediate attention to avoid further damage or unsafe driving conditions.This light differs from the Service Engine Soon warning light, which typically means it is time for service for the vehicle.
Common Causes of the Check Engine Light
Here are some potential reasons this light might appear:
- Loose or Faulty Gas Cap: A damaged or improperly tightened gas cap can cause fuel vapor leaks, which trigger the light.
- Worn-Out Spark Plugs or Ignition Coils: These are essential for the engine's combustion process, and issues here can lead to misfires.
- Malfunctioning Oxygen Sensor: This sensor monitors the oxygen
