Engine Diagnostic and Performance


Since 1996, every vehicle has been equipped with an On-Board Diagnostics (OBD) system, which monitors engine performance and emissions. This system scans sensors throughout the vehicle for abnormalities, generating diagnostic trouble codes (DTCs) when issues arise. These codes aid mechanics in diagnosing and addressing problems efficiently.
