At some point, almost every vehicle owner will experience the moment when the check engine light (CEL) illuminates on the dashboard. It’s an indicator that something is amiss with your vehicle. The severity of the issue can vary widely. A & R German Motors, a trusted auto mechanic shop in Hermosa Beach, is here to guide you through understanding the implications of your car’s check engine light and the risks of ignoring it. Let’s delve into what the check engine light means and whether it’s safe to continue driving your vehicle when it’s on.
Note: You will not pass a Smog Check in California when a CEL is on.
Understanding the Check Engine Light::
What Does the Check Engine Light Mean?
The check engine light is part of your vehicle’s onboard diagnostics system (OBD-2), which monitors various systems and components for errors. When the OBD-2 detects a problem it cannot correct, it triggers the CEL as a warning. The issues can range from minor, such as a loose gas cap, to severe, like a malfunctioning catalytic converter or Oxygen Sensor.
Immediate Action vs. Observation
When the check engine light comes on, it’s crucial to assess the nature of the indicator. A steady light typically suggests a non-emergency issue that needs attention soon. In contrast, a flashing light indicates a more severe problem that requires immediate attention to prevent significant damage to your vehicle.
Risks of Ignoring the Check Engine Light::
Potential for Greater Damage
Ignoring the check engine light can lead to more significant, more costly problems down the line. If addressed, what might start as a minor issue can escalate into a major repair. For instance, a misfire can quickly harm the catalytic converter, producing an expensive replacement.
Safety Concerns
Specific issues signified by the CEL can pose safety risks. For example, a malfunctioning oxygen sensor might seem minor. Still, it can result in irregular engine performance, potentially causing stalling or difficulties handling the vehicle under certain conditions.
When to Stop Driving Immediately
If the check engine light flashes, it’s a signal to stop driving as soon as it’s safe. A flashing light often indicates a severe engine misfire, allowing unburden fuel to dump into the exhaust system. This can raise the temperature of the catalytic converter to dangerous levels, risking damage to the vehicle.
