When your vehicle’s Check Engine Light (CEL) illuminates, it can be a cause for concern. This seemingly innocuous light on your dashboard signifies that your car’s onboard diagnostic system has detected an issue with the engine or related components. At Yorba Linda Auto Service, we offer expert Check Engine Light Services to diagnose, address, and resolve these issues efficiently. Our comprehensive service ensures your vehicle runs smoothly, maintaining performance and avoiding potential long-term damage.
Understanding the Check Engine Light
The check engine light is a part of your vehicle’s onboard diagnostics system (OBD). It monitors various systems in your car, such as the engine, transmission, exhaust, and emissions. When the system detects an issue, it triggers the check engine light to alert you that something needs attention. The problem could be as simple as a loose gas cap or as complex as a failing catalytic converter.
Why You Shouldn’t Ignore the Check Engine Light
While it might be tempting to ignore the check engine light, especially if your car seems to be running fine, doing so can lead to significant issues. Some common reasons the check engine light might come on include:
1. Oxygen sensor failure
This sensor measures the amount of unburned oxygen in the exhaust system. A faulty oxygen sensor can lead to poor fuel economy and increased emissions.
2. Catalytic converter issues
The catalytic converter helps reduce harmful emissions. If it fails, it can cause your vehicle to run poorly and potentially fail an emissions test.
3. Ignition coil or spark plug problems
These components are crucial for igniting the fuel in your engine. If they are malfunctioning, it can lead to misfires, reduced performance, and engine damage.
4. Mass airflow sensor malfunction
This sensor monitors the air entering the engine and ensures the correct fuel-to-air ratio. A malfunction can cause your engine to run too lean or too rich, affecting performance and emissions.
