check engine light

Your vehicle’s check engine light is a warning system made to alert you to potential issues under the hood. While the cause may be something minor, it could also indicate a more serious problem requiring immediate attention. At Toole's Garage, our expert technicians provide professional diagnostics and repair services to accurately identify and resolve check engine light issues.


Modern vehicles rely on an onboard computer system to monitor engine performance, emissions, and critical components. When the check engine light turns on, it means the system has detected an abnormality. Our technicians at every location use state-of-the-art diagnostic tools to retrieve error codes, inspect affected components, and determine the best course of action for repairs.


Ignoring a check engine light can lead to reduced performance, lower fuel efficiency, and costly repairs down the road. Whether it’s a faulty sensor, ignition issue, or emission system problem, Toole's Garage has the expertise to diagnose and fix the issue efficiently.


Check Engine Light FAQs

Why did my check engine light turn on?

The check engine light can illuminate for various reasons, including a loose gas cap, failing oxygen sensor, faulty spark plugs, or an issue with the catalytic converter. A diagnostic scan and inspection are the best way to determine the exact cause.


Can I keep driving with the check engine light on?

If the light is steady, you may be able to drive temporarily, but it’s best to have it checked as soon as possible. A flashing check engine light, however, indicates a more serious issue that requires immediate attention.


How do you diagnose a check engine light issue?

Our technicians use advanced diagnostic scanners to retrieve error codes from your vehicle’s computer system.
