Frequently Asked Questions

  • What does a vehicle diagnostic test check for?

    A vehicle diagnostic test scans your car’s onboard computer systems to detect issues related to the engine, transmission, exhaust, brakes and other key components. It can identify sensor faults, misfires, fuel system problems, emission control issues and more. Technicians then use this information to determine what repairs are needed. It’s a vital first step in fixing any modern vehicle issue.

  • How long does a vehicle diagnostic take?

    Most vehicle diagnostic tests take between 30 to 60 minutes, depending on the complexity of the issue and the vehicle type. If further inspection or testing is required, your mechanic may need additional time. A thorough diagnostic ensures you avoid unnecessary costs by identifying the root of the problem.

  • Why is my check engine light on?

    The check engine light can indicate a wide range of problems—from a loose fuel cap to more serious issues like oxygen sensor failure or engine misfires. While some causes are minor, others can lead to serious damage if ignored. A diagnostic test helps determine the exact reason so it can be addressed quickly and accurately.
