    Accurate, honest engine diagnostics at O'Brien's Auto Repair in Cape May County. With 40-plus years of dealership-trained experience, Jim identifies problems correctly the first time, saving you money on unnecessary repairs.

    A check-engine light is a clue, not a diagnosis. The code tells you which system complained — not which part failed. Real diagnostics combine the scan with testing (sensors, wiring, fuel trim, vacuum, compression) so you pay to fix the actual cause instead of replacing parts on a guess.

    • OBD-II scan tool diagnostics
    • Check engine light analysis
    • Drivability symptom diagnosis

    What to expect

    1

    Scan & interview

    We pull the stored codes and freeze-frame data and ask when and how the symptom shows up.

    2

    Test, don't guess

    The suspect circuit or component is actually tested, so the estimate covers the real fix — not a parts-cannon list.

    3

    Fix & verify

    After the repair, codes are cleared and the car is driven to confirm the fix held and no new codes set.
