Check Engine Light & Vehicle Diagnostics
Don't Ignore That Light. Get a Straight Answer Today.
That check engine light on your dashboard can mean dozens of different things, and ignoring it rarely makes the problem go away. If your check engine light is on bring your vehicle to Double Decker Auto Repair for a fast, accurate diagnostic scan. We'll tell you exactly what the code means, what's causing it, and what it will take to fix it.
Our technicians use professional-grade OBD-II diagnostic equipment to pull fault codes from your vehicle's onboard computer and identify the root cause of the problem not just the symptom. Whether it's an oxygen sensor, a misfiring cylinder, an evaporative emissions issue, or something more complex, we give you a clear explanation and a written estimate before any repairs begin.
​
A check engine light doesn't always mean disaster. Sometimes it's a loose gas cap. But sometimes it's an early warning sign of a problem that if ignored will become a much more expensive repair. Getting it diagnosed early provides peace of mind and can help avoid a more costly problem and repair.
