• Engine Damage: Low oil levels can lead to insufficient lubrication of engine components, causing increased friction and heat. This can result in engine damage or excessive wear on critical parts, which may lead to sensor readings that trigger the check engine light.

If your check engine light comes on, it's essential to have your vehicle's diagnostic trouble codes (DTCs) read with an OBD-II scanner. These codes will provide specific information about the problem that triggered the light. If low engine oil is the issue, topping up the oil to the recommended level may resolve the problem.
