What is the first thing to check when the check engine light comes on?

• First, ensure the gas cap is tightened. Many emissions-related codes stem from an improperly sealed fuel cap and can be resolved quickly.
• If tightening doesn’t help or the light flashes, do not continue driving. A flashing check engine light often indicates a severe condition that could harm the hybrid system or catalytic converter.
