Engine Diagnostic

When your Check Engine Light comes on or your vehicle suddenly starts running differently, knowing what's wrong is the first step toward the right repair. Modern vehicles use sensors, computers, and electronic control systems to monitor engine performance, emissions, fuel delivery, ignition, and other components. A diagnostic trouble code can provide an important clue, but it doesn't always identify the failed part on its own.

At Waterside Auto Repair, we provide professional engine diagnostics to identify the source of warning lights, drivability problems, unusual engine behavior, and other performance concerns. Our technicians combine diagnostic scanning with visual inspection, testing, and vehicle-specific information to determine the most likely cause. Once we identify the issue, we'll explain our findings and recommend the appropriate repair.

FAQ

  • Engine diagnostics is the process of identifying the cause of an engine or drivability problem using diagnostic equipment, vehicle information, visual inspection, and additional testing when necessary.

  • A Check Engine Light indicates that the vehicle's computer has detected a condition that may require attention.

    The cause can range from an emissions issue to an engine, fuel, ignition, electrical, or other system problem.

    A diagnostic inspection is needed to determine the cause.

  • Not necessarily.

    A diagnostic trouble code identifies a condition detected by the vehicle's computer. Additional testing is often necessary to determine which component or system is actually responsible.

  • Yes. Our technicians can use diagnostic equipment and additional testing to help identify the cause of the warning light.

  • A flashing Check Engine Light can indicate a condition that may cause damage if the vehicle continues to operate, particularly when accompanied by a misfire or poor engine performance.

    Have the vehicle inspected promptly.

  • A rough-running engine can have many causes, including ignition problems, fuel delivery issues, vacuum leaks, sensor problems, air intake restrictions, or mechanical problems.

    Diagnostics can help narrow down the cause.

  • Loss of power can be related to engine, fuel, ignition, exhaust, transmission, electrical, or other vehicle systems.

    A diagnostic inspection can help determine where the problem originates.

  • Yes. Intermittent problems can sometimes be more difficult to reproduce, but technicians can use stored diagnostic information, symptoms, visual inspection, and additional testing to help identify the cause.

  • No.

    Engine diagnostics identifies the source of a problem.

    Engine repair is the physical repair or replacement of the component causing the problem.

    For example, diagnostics may determine that a vehicle has an ignition problem, while the subsequent repair could involve replacing a faulty ignition component.
