What to Expect from Our Diagnostic Process
A check engine light diagnosis at Christian Brothers Automotive Broomfield follows a clear, three-step process. Our skilled technicians don’t just read the stored trouble code and hand you a repair order. A code tells us where to start testing, not which part to replace. We assess the related systems, verify the actual failure, and then walk you through what we found in plain language. No jargon. No surprises. You review every repair option and give approval before any work begins.
1. Schedule Your Appointment
Whether scheduling online or over the phone be sure and let us know what you're experiencing so we can provide fast and accurate service advice.
2. Diagnostics and Inspections
Drop off your vehicle and the shop will get to work with inspections and diagnostics using the same equipment as the manufacturers to determine issues and next steps.
3. Digital Vehicle Inspection Report and Estimate
Following the diagnosis we will text you a digital vehicle inspection report, containing pictures and videos of our findings and recommendations.
4. Review and Approval
A service advisor will reach out to walk you through the findings and recommendations to determine how you would like to proceed, or you can approve work directly in your DVI.
5. Work Performed or Scheduled
Most work can be completed immediately, or scheduled based on parts and customer availability.
See Exactly What Our Technicians Found
Every visit includes a free Digital Vehicle Inspection (DVI), a photo-documented review of your vehicle taken during the service. You receive actual photos of the components our skilled technicians inspected, so you can see the findings for yourself before deciding on any repair. There’s no need to take our word for it.
We also perform a complimentary Courtesy Inspection covering major systems including lights, brakes, suspension, tires, and battery. It’s one more way we help you leave with a complete picture of your vehicle’s condition.
Check Engine Light Services in Broomfield: What You Should Know
The check engine light can be triggered by dozens of different faults. Common causes include a faulty oxygen sensor, failing catalytic converter, loose or damaged gas cap, misfiring spark plugs, and mass airflow sensor issues. A free code scan from an auto parts store will show a stored trouble code, but it won’t tell you whether a sensor has actually failed or which component needs replacement. That distinction matters: replacing parts based on a code alone often doesn’t fix the underlying problem.
Our Full Service Diagnostic Testing uses manufacturer-quality equipment to go beyond basic scanner codes and assess your vehicle’s systems comprehensively. Driving with the light on for an extended period can reduce fuel efficiency and cause secondary damage, so early diagnosis helps protect both your vehicle and your wallet.
Broomfield and Westminster drivers can schedule check engine light diagnostics online or by calling (720) 706-3763. Christian Brothers Automotive Broomfield backs every repair with the Nice Difference Warranty (3 years/36,000 miles) and the J.D. Power 2025 #1 customer satisfaction recognition. (For J.D. Power 2025 award information, visit jdpower.com/awards.)
Flashing vs. Steady: How Urgent Is Your Check Engine Light?
A steady check engine light means a fault has been stored and should be diagnosed soon. It doesn’t usually require pulling over immediately, but it shouldn’t be ignored for weeks. A flashing light is a different situation. It typically signals an active engine misfire that can damage the catalytic converter quickly. If your light is flashing, reduce speed and seek service promptly.
Check Engine Lights & Colorado Emissions Testing
In Broomfield and surrounding counties, emissions testing may be required for vehicle registration. An illuminated check engine light with an active emissions-related code will typically cause your vehicle to fail the emissions inspection. That means resolving a check engine light before your registration renewal isn’t just about the repair; it’s about staying road-legal. Our Broomfield shop can diagnose and address emissions-related faults so you can be better prepared when inspection time comes.

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.
-

"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.

-
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.
