A service advisor walks you through every finding and recommendation. You approve the work directly through the digital vehicle inspection report or by phone. Nothing moves forward without your go-ahead.

Some repairs can be completed the same day. If parts need to be ordered or timing doesn’t work, we’ll schedule around you.
Common Reasons Your Check Engine Light Is On
Your check engine light can signal anything from a loose gas cap to a failing catalytic converter. Here are the most frequent causes we see in Aurora, CO vehicles:
- Loose or damaged gas cap: Fuel vapors escape when the cap isn’t sealing properly, which is enough to trigger the light. It’s one of the simplest fixes and worth checking after every fill-up.
- Faulty oxygen sensor: A failing O2 sensor affects fuel efficiency and emissions output and is one of the most common check engine light causes across all vehicle types.
- Catalytic converter failure: Often a downstream result of deferred maintenance or engine misfires, catalytic converter problems typically appear alongside performance issues.
- Spark plug or ignition coil problems: These cause engine misfires, rough acceleration, and elevated emissions, and they commonly trigger the check engine light.
- Mass airflow sensor malfunction: A failing MAF sensor disrupts the air-fuel mixture, leading to rough idling, hard starts, and reduced fuel economy.
- Vacuum leaks and EGR valve issues: Particularly common in higher-mileage vehicles and in Colorado’s range of driving conditions, these can trigger the light without obvious drivability symptoms.
Steady Light vs. Flashing Light: What the Difference Means
Not all check engine lights carry the same urgency. A flashing check engine light indicates a serious problem, often a cylinder misfire, that can cause costly and dangerous damage if you keep driving. Pull over safely and call us at (720) 571-4980.
A solid check engine light typically means your vehicle is releasing an irregular amount of emissions due to a problem and should be serviced as soon as possible. There may be no obvious symptoms yet, but fuel economy and performance can already be affected. A steadily lit light can also indicate that a sensor is out, but professional diagnosis is the only way to confirm it.

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. "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.
