Engine Diagnostics and Performance

Every vehicle built since 1996 is equipped with an On-Board Diagnostics (OBD) system that constantly monitors engine performance. When the system detects irregularities, it records diagnostic trouble codes and alerts you through the “check engine” or “service engine” light. When that light appears, scheduling an engine diagnostic or tune-up is the best next step to identify and correct the issue before it worsens.

During a diagnostic service, our technicians use advanced tools to read your vehicle’s stored codes and pinpoint the source of the problem. The information gathered helps determine the specific repairs or maintenance needed to restore engine health. Common issues include powertrain malfunctions, faulty sensors, or worn ignition and fuel system components. Regular engine tune-ups—such as replacing spark plugs, filters, wires, and belts—help prevent these issues, improve fuel efficiency, and extend the life of your vehicle.

Consistent engine maintenance keeps your vehicle running smoothly, but it’s equally important to recognize when a problem requires attention. A glowing “check engine” light, slow cranking, rough idling, or stalling can all signal that your engine needs service. You might also notice reduced power, knocking or pinging sounds, or poor fuel economy—each an indicator of performance decline.

At Northfield Auto, we use professional diagnostic equipment to retrieve fault codes from your OBD system, inspect critical components, and perform the necessary repairs or tune-ups. From spark plug replacement to emissions and fuel system checks, our goal is to keep your engine reliable and performing at its best.
