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.

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.

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.
