What Is an Engine Diagnostic Test?

An engine diagnostic is a test that helps mechanics figure out what's wrong with your car by using a computer to read messages from your car's internal system.

Understanding the Process

Using advanced computerized equipment, our technicians will run an engine diagnostic to "communicate" with your vehicle's internal systems. The results allow us to identify issues that may not be visible during a standard inspection.

What We Check

Our team will scan your vehicle's onboard computer to look for trouble codes related to:

  • Engine performance
  • Emission systems
  • Ignition timing
  • Fuel injection
  • Transmission issues

We also perform a thorough visual inspection to ensure no detail is missed.

Reviewing the Results With You

Once the test is complete, we will go over the results with you in plain language. You'll understand what is happening under the hood and what your options are. No jargon. No pressure. Just clear, transparent answers from trusted professionals.

Why You Might Need a Diagnostic Test

If your check engine light is on, your vehicle is trying to tell you something, but sometimes you might have problems before the light shows up. 

Common Signs Something's Wrong

Common symptoms that signal the need for an engine diagnostic include:

  • The check engine light is flashing or stays illuminated
  • Strange noises or smells from the engine
  • Reduced fuel efficiency
  • Trouble starting or rough idling
  • Sluggish acceleration

If you notice any of these issues, even if only intermittently, it's time to book an inspection at Visalia Toyota.

Prevent Bigger Repairs

An early diagnosis could save you from expensive repairs later. Even if your car appears to be running normally, Cars.com recommends you do not ignore the check engine light. Your check engine light can indicate a minor, relatively inexpensive problem, that if not fixed, could create a comparatively more expensive issue down the road. Ignoring the check engine also allows you to overlook new problems arising that would have been indicated by an illuminated check engine light.
