Check Engine Light Diagnostics in Denver, CO
That steady, glowing amber light on your dashboard—the check engine light—can be a source of major stress and confusion. It’s your vehicle’s way of telling you that something is wrong, but it doesn’t tell you what. At Denver Auto Repair and Service, we take the guesswork out of the check engine light. Our expert mechanic team uses advanced diagnostic equipment to accurately pinpoint the problem and recommend the right repair.
Don’t let a small warning turn into a major headache. Our comprehensive diagnostic service is the first step to getting you back on the road with confidence and peace of mind.

Why You Should Never Ignore Your Check Engine Light
- Reduced Fuel Economy: The problem causing the light could be making your engine work harder and burn more gas.
- Increased Emissions: Your vehicle may not pass a Colorado emissions test if the check engine light is on.
- Catastrophic Engine Damage: A seemingly minor issue, like a sensor failure, can lead to expensive damage to critical components like your catalytic converter.
- Unpredictable Breakdowns: You could be left stranded on the side of the road at the worst possible time.
Our Advanced Diagnostic Process
Any auto parts store can “pull a code,” but that code is just a starting point. It tells you which system is reporting a problem, not what the problem is. Our ASE Certified technicians perform a complete diagnostic process.

Code Retrieval & Analysis
We connect our state-of-the-art OBD-II scanner to your vehicle's computer to retrieve the specific trouble codes and live data streams.

Thorough Vehicle Inspection
Our mechanic performs a detailed visual inspection of the related systems, checking for worn parts, loose connections, or damaged wiring.

Pinpoint Testing
We perform targeted tests on specific components (like sensors, ignition coils, or fuel injectors) to confirm the exact point of failure.

Clear Explanation & Honest Recommendations
Once we identify the problem, we explain it to you in plain English and provide a detailed estimate for the necessary repair. No work is ever done without your approval.
