Auto Engine Diagnostics
Check Engine Light On? We Come to You.
When your check engine light turns on, it can feel overwhelming. You’re not sure what’s wrong, and getting to a repair shop can take up hours you don’t have. That’s where Gearhead San Diego Mobile Mechanic steps in. We bring full engine diagnostics right to your location—home, work, or wherever your car is parked. No towing. No waiting rooms. Just fast, honest answers from a trusted local mechanic, right where you need them.

What Is Engine Diagnostics?
Engine diagnostics is a quick and efficient way to find out what’s going on under the hood—without taking your car apart. Most modern vehicles have built-in computer systems that monitor how your engine and other components are performing. When something isn’t working right, your car stores a code that points us in the right direction.
At Gearhead San Diego, we use professional-grade diagnostic scanners to read those codes. This tool connects to your car’s onboard computer and helps us spot issues with your engine, transmission, exhaust system, and more. Once we’ve read the codes, we’ll explain what they mean in plain English and let you know the best way to fix the problem—no guesswork, just clear answers.
