Why is my Check Engine Light On?

First, is the light blinking or persistently on? A blinking check engine light typically indicates a serious issue, such as an engine misfire, which can lead to significant damage if not addressed immediately. If the light then becomes steady, it means the problem is still present but may not be as urgent. Here’s what each means:

Blinking Check Engine Light:

• Serious Problem: Often indicates a misfire or other critical issue.

• Immediate Attention Needed: You should stop driving as soon as it’s safe and have the vehicle checked.

Steady Check Engine Light:

• Persistent Issue: Indicates a problem that needs to be diagnosed but is not immediately threatening.

• Schedule a Check-Up: It’s important to have a professional diagnose the issue to prevent further damage.

In both cases, having a professional assess the vehicle is essential to ensure it runs safely and efficiently.
