What is Car Diagnostic Testing?

Car diagnostic testing is like a health checkup for your vehicle. Modern cars are packed with sensors and onboard computers that monitor everything from engine performance to emissions. When something’s off, that little orange check engine light pops up—and it’s your car’s way of saying “Help!”

At Mac’s Automotive, we use advanced diagnostic scanners to read your car’s trouble codes. But we don’t stop there. Our certified technicians interpret the data, inspect the system, and explain everything in simple terms. We’ll never leave you guessing.

Why Your Check Engine Light Might Be On

The check engine light can mean something as minor as a loose gas cap or as major as engine misfiring. Common issues include:

  • Faulty oxygen sensors

  • Loose or broken gas cap

  • Bad spark plugs or wires

  • Failing catalytic converter

  • Mass airflow sensor malfunction

  • Transmission issues

Ignoring it can lead to bigger (and more expensive) problems. That’s why timely diagnostic testing is so important.

Voice Search-Friendly FAQs

Why is my check engine light flashing?
A flashing light usually means something serious—like a misfire—that could damage your catalytic converter. Stop driving and bring it to us ASAP.

Can I drive with the check engine light on?
If the light is steady and your car feels normal, it’s usually safe for short distances—but you should get it checked soon. If it’s flashing or the car runs rough, have it towed in.

How long does a diagnostic test take?
Most tests take 30–60 minutes. If the issue’s more complex, we’ll let you know and keep you updated.

Do you need an appointment for diagnostics?
Walk-ins are welcome, but scheduling an appointment helps us serve you faster.

Will a diagnostic tell me exactly what’s wrong?
Yes and no—scanners pull error codes that point us to a system or component, but it’s the technician’s job to test, verify, and confirm the actual issue.

With our diagnostic services, we can quickly identify the underlying cause and recommend the best course of action for repairs.

What Happens During a Diagnostic Test?

We connect your vehicle’s computer system to our specialized equipment during a diagnostic test. This allows us to read any error codes stored in the system, which provide clues about what might be wrong. These codes can point to issues with the engine, transmission, exhaust system, or other components. Our technicians use this information and a physical inspection to pinpoint the problem and determine the necessary repairs.

Common Issues Detected by Diagnostics

Vehicle diagnostics can reveal many problems, from minor sensor malfunctions to more severe issues like failing catalytic converters or misfiring engines. If your check engine light is on, it could indicate anything from a loose gas cap to a faulty oxygen sensor. Our skilled technicians will explain the diagnostic test results and discuss the best solutions to restore your car to peak performance.

Staying Proactive with Regular Diagnostics

Even if your check engine light isn’t on, it’s a good idea to have routine diagnostic tests performed, especially if you notice any changes in how your car runs.
