A stored fault code identifies the system that reported a problem. Our diagnostic process tests that system to find the responsible component or condition. You receive the findings, recommendations, and estimate before deciding whether to authorize a repair.
The process starts when you schedule an appointment. Once your vehicle is in our bay, our ASE-certified technicians use manufacturer-quality equipment to evaluate the affected systems and conduct a full Digital Vehicle Inspection (DVI). We text the report to you with photos and videos showing what our technicians observed.
Your service advisor reviews the results and recommendations in plain language, using the documented observations when helpful. You can ask questions before making a decision. We provide an estimate and require your approval before repair work begins.
We strive to provide same-day diagnostic service when available, and we accommodate most customers within one business day. Timing depends on the vehicle’s condition and the testing required to confirm the fault. When parts and authorization are in place, we can often complete the repair that day. Otherwise, we’ll arrange the work around parts availability and your schedule. We also work with all major extended warranty providers on covered check engine light repairs.
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.
We Keep Your Day Moving
A check engine light diagnostic doesn’t have to derail your schedule. Our complimentary shuttle service is available for local trips while your vehicle is in our care. If you’d rather wait, our shop offers free Wi-Fi and a comfortable, welcoming environment.
Every visit also includes a Courtesy Inspection covering your vehicle’s major systems: lights, brakes, suspension, tires, and battery. It’s one more way we give you a complete picture of your vehicle’s condition.
What to Tell Us About Your Check Engine Light
The details you notice before check-in help us understand the concern and when it occurs.
Let us know:
- Whether the check engine light is steady or flashing
- Whether you’ve noticed rough running, loss of power, unusual smells, stalling, or another change in vehicle behavior
- When the light first appeared and whether it stays on or comes and goes
You don’t need to identify the cause yourself. Simply describe what you saw, heard, or felt while driving, including the conditions under which the symptoms appeared.
Steady Light vs. Flashing Light: What Each Means
A steady check engine light means the OBD-II system detected a fault affecting emissions or engine performance. If the vehicle has no other symptoms, drive carefully to a nearby shop for diagnostic service. Don’t defer the inspection indefinitely because the underlying problem remains active even when the vehicle seems to run normally.
A flashing check engine light signals an active problem that often involves a cylinder misfire. Continued operation can damage the catalytic converter and increase repair costs. Have the vehicle evaluated as soon as possible rather than continuing with normal driving.
If either type of check engine light appears with rough running, loss of power, or unusual smells, pull over and stop driving. Those symptoms require prompt evaluation before the vehicle returns to the road.

Common Check Engine Light Triggers
A check engine light can originate in several monitored engine or emissions-control systems, and one diagnostic trouble code can have multiple possible causes.
Common causes include:
- Loose or faulty gas cap causing pressure loss in the fuel system
- Failing oxygen sensor affecting the air-fuel mixture and emissions
- Failing catalytic converter reducing emissions-control system efficiency
- Cylinder misfire (P0300 series codes) from worn spark plugs or ignition wires
- Failing mass air flow (MAF) sensor disrupting fuel-delivery calculations
- EGR valve malfunction affecting exhaust gas recirculation
- Vacuum leaks introducing unmetered air into the engine
Reading the OBD-II trouble code identifies the system that reported a problem. It doesn’t confirm which component failed or whether wiring, airflow, fuel delivery, or another condition caused the fault. Inspection and testing of the affected system establish the root cause before we recommend a repair.
Clearing a trouble code without correcting the underlying issue can cause the check engine light to return. Full service diagnostic testing addresses the fault behind the code instead of treating the code itself as a complete diagnosis.

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.
