Diagnostic Services

Is your Check Engine light on? Is your vehicle starting to drive strangely, unlike what you're used to? What could be the problem?


It's important to find the root of the problem – and fast – so you fix the issue at its source, before it becomes a bigger problem for you on the road.

Automotive Diagnostics Pomona


At Purrfect Auto in Pomona, we offer extensive Diagnostic Services to do just that. Whether your warning light just started blinking, is holding steady, or something just feels "off" when you drive, our team can help. Conveniently located, we'll pay quick attention to those warning signs to find out what's going on under the hood, and save you from paying thousands on repairs later on.


Your car's dashboard can display an array of different lights and warnings, each giving you a signal that it's time to take a look. Some might be minor or simple fixes, while others can be critical issues. Purrfect Auto can address all of them, including:

  • Engines Diagnostic
  • Transmission Diagnostic
  • Electrical Diagnostics
  • Differential Diagnostics
  • ABS Diagnostics
  • Air Bag Diagnostics
  • Cylinder head gasket services


Your vehicle comes with complex connected computer systems, constantly monitoring pressure and levels and other important factors that keep your car or truck running properly. When one of those factors is off, the system alerts you that something may be wrong.


Purrfect Auto has the tools and technical knowledge to properly diagnose your problem. We'll retrieve data from your vehicle's computer system, including the error code and sensor data and we'll run tests to make sure your monitoring systems are functioning correctly.  Once we've found the source of the warning, we'll run further tests to confirm and then provide you with our diagnosis – and our recommendation for repairs, if needed. And it can all be done same-day!


When your vehicle's dashboard warning lights come on, don't hesitate. Come on down to Purrfect Auto for expert diagnostic services and get yourself back on the road safely and quickly.
