At Olmsted Auto Care in Olmsted Township, OH, we know an illuminated check engine light can feel like a dark storm cloud over your day. That’s why our check engine light (CEL) services are designed to quickly identify and address the root of the issue, giving you peace of mind.

Why is the Check Engine Light On?

The CEL often signals a potential issue with your vehicle’s drivability or electrical systems. Whether you drive a Mazda, Mercedes, Mitsubishi, or another brand, if the light is steady, the issue may not be urgent, but an inspection is still important. However, if the light flashes, it needs immediate attention—pull over and give us a call. 

Common causes of a lit CEL include:

• Oxygen sensor failure 

• Loose fuel cap 

• Catalytic converter issues 

• Ignition coil or spark plug problems 

• Mass airflow sensor failure
