Auto Engine Diagnostics

Fast, Reliable Answers with Onsite Service – Gearhead San Diego Mobile Mechanic

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.

Common Signs You Might Need an Engine Diagnostic

Not Sure If You Need an Engine Diagnostic?


Here are some common signs that it might be time to have your car checked out:

  • Check Engine Light Is On
  • If that little light on your dashboard comes on, your car is telling you something’s not right. A quick diagnostic scan can tell us exactly what’s going on
  • Strange Noises
  • Hearing clunks, knocks, or squeals under the hood? These sounds could be signs of engine trouble that shouldn’t be ignored.
  • Rough Idling or Stalling
  • If your car is running unevenly, shaking at stoplights, or stalling unexpectedly, a diagnostic can help pinpoint the issue.
  • Poor Fuel Efficiency
  • Not getting as many miles per gallon as usual? It could be a sensor, filter, or engine problem that needs attention.
  • Car Won’t Start
  • Whether it’s a battery, starter, or something deeper in the system, diagnostics help us figure out what’s preventing your car from starting.
