Check Engine Light: What You Need to Know

What does it mean when my check engine light comes on?

A glowing check engine light means that the onboard diagnostic system has detected a problem affecting the emission controls. There are dozens of possibilities as to why it has illuminated. It could be something as simple as a loose gas cap, bad airflow, a bad oxygen sensor or a faulty catalytic converter. When this warning light comes on, it generates a trouble code that can be read by connecting a diagnostic scanner to the vehicle's onboard diagnostic system; that will steer your mechanic to specific areas and help find the cause. A flashing check engine light means the problem is serious enough that it warrants immediate attention to prevent expensive repairs. Stop as soon as it is safe to do so.

While you’re there, let us perform an A thru S® Courtesy Check, which includes a visual check of the following items:

  • Engine air filter
  • Brake fluid
  • Power steering fluid
  • Automatic transmission fluid
  • Coolant/antifreeze
  • We'll also walk you through your vehicle manufacturer's
    recommendations for replacing these vital fluids and filters.

With a Car Repair Service oil change, or any other service, you’ll receive an A thru S® Courtesy Check. We’ll look inside, outside, under the hood and underneath the car, then explain the findings and give you a written report.

Should I Worry About How Hot My Engine Is Running?

Wondering whether or not you should be worried about your engine overheating? You should be very concerned, because an overheated engine can be far more than an inconvenience. In extreme cases, driving a car with an overheated engine even a short distance can destroy the cylinder head, engine block or internal parts.
