What Your Check Engine Light Is Actually Telling You
The malfunction indicator lamp, what most drivers call the check engine light, activates when your vehicle’s onboard diagnostic system detects a fault affecting engine performance or emissions. The signal doesn’t tell you what failed. It tells you something needs attention.
Solid Light vs. Flashing Light
How the light behaves matters. A solid, steady light means a fault has been stored and your vehicle should be inspected soon. It may still drive, but the underlying issue can quietly reduce fuel economy and performance over time. A flashing light is more urgent. It typically signals an active fault such as a cylinder misfire that can damage the catalytic converter if ignored. If your light is flashing, or if you notice rough running, power loss, or unusual noises alongside it, don’t delay.
Common Causes
Many different faults can trigger the check engine light, including:
- A loose or failing gas cap
- A worn oxygen sensor
- Degraded spark plugs or ignition coils
- An evaporative emissions (EVAP) system leak
- A catalytic converter fault
Why a Parts-Store Code Scan Isn’t Enough
A free scan at a parts store retrieves stored trouble codes, but a code points to a system, not a specific component. Confirming the actual cause requires live data analysis, circuit testing, and component verification. That’s what our Full Service Diagnostic Testing is built to provide. Commerce City drivers, and those coming in from Brighton, can bring any make or model to our shop for efficient and accurate check engine light diagnostics.

FAQs
-
Q. "What is the difference between a steadily lit and a flashing check engine light?"A steadily lit light means that a sensor is sending a signal to your vehicle's computer that something is wrong or it could simply mean that the sensor is out. If your check engine light is flashing, however, that means there is a serious issue and you should stop driving immediately.
-
Q. "Why is my check engine light on but nothing seems to be wrong with my vehicle?"If nothing within your vehicle stands out, then it is possible that it is just a minor issue such as a loose gas cap or a bad O2 sensor. It is still recommended to see a mechanic if the light doesn't disappear to check for any larger issues.
-
Q. "Do you offer a warranty?"As part of our Nice difference.® commitment to providing our customers the best auto service experience possible, we also offer a3-year/36,000-mile warranty on all the work that we do. We offer this warranty at every Christian Brothers Automotive nationwide, and it will be honored at any location, regardless of which branch did the initial work.
-
Q. "Can you provide service under my extended warranty?"Yes. At Christian Brothers Automotive, we work with all major extended warranty providers to make needed repairs for our customers. If you have an extended warranty, you can discuss your carrier with our team when scheduling an appointment and confirm that the work will be covered. You can find a partial list of the extended warranty companies we work with here.
-
Q. "What to do if your check engine light turns on?"We recommend heading to your local auto shop as soon as you are able. This is typically a sign that there is an abnormality within your engine.
-
Q. "Is it safe to drive your car when the check engine light is on?"It depends. If you are experiencing other noticeable issues with your vehicle, it may be best to pull over. Otherwise, it is typically okay to drive to your local auto shop. You will want to get this checked sooner rather than later to avoid being stranded with a broken-down car.
