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.

The Importance of Proper Torque on Lug Nuts

April 28, 2025
When it comes to wheel safety, lug nuts don’t always get the attention they deserve. These critical fasteners are what keep your wheels securely attached to your car, and they need to be tightened to a very specific level of force—known as torque. Get it wrong, and you're risking more than just a loose wheel.

Subaru: Ever Popular in the Bay Area

April 13, 2025
It’s difficult to drive anywhere in the Bay Area and not see a lot of Subaru vehicles. Whether it’s the Subaru Crosstrek, WRX, Outback, Forester, or Ascend, Subaru vehicles are everywhere. At Toole’s Garage we are big Subaru fans. Subaru vehicles are built for the great outdoors, and of course California provides plenty of opportunity for on-road and off-road adventures. All wheel drive (AWD) comes standard on many Subaru models, and can provide consistent traction whether you are on a muddy road, or skiing in the Sierras. If a roof rack did not come standard with your model, it’s easy to add. And of course, interior space is pretty generous, especially if you drive an Outback or Ascent – you can stow plenty of camping and hiking gear. At Toole’s Garage we can provide your Subaru with the maintenance it needs to provide you with a reliable ride – wherever your adventures take you. We highly recommend regular oil change – it not only improves performance and extends engine life, but it also allows us to inspect various sub-systems of your Subaru to catch any impending problems (for example, older Subaru models were prone to oil leaks). And if a long summer trip is in the cards, we definitely suggest bringing it in for a checkup. Being a full service auto repair shop, Toole’s Garage can provide your Subaru with routine maintenance services, diagnostics, as well as major repairs. If your Subaru needs new brake pads, has the check engine light “on”, suffers from transmission problems, or needs major engine repairs – we can make your vehicle healthy again. Whether you have owned your Subaru for a long time, or have recently acquired one, bring it to our San Carlos auto repair shop – we will keep your vehicle in peak condition. Call us to make an appointment, or you can make an appointment online, on our website.
