Understanding The Check Engine Light

Did your check engine light suddenly come on? Welcome to the joys of vehicle ownership. The check engine light is one of the many warning lights that can appear in your dashboard when something is not right. The engine light is unique in that it’s part of the onboard diagnostics system (OBD-II) of your vehicle. Every vehicle manufactured for the United States since 1996 is equipped with the system. It monitors the engine, transmission, and exhaust system to ensure proper performance from all three components. If it detects an issue, it will do two jobs simultaneously. It sends the respective diagnostic trouble code (DTC) to the car’s computer system, which will require a check engine light diagnostics service for retrieving and trigger the check engine light to come on. When you notice the light in your dashboard, it’s important to schedule an appointment at your earliest convenience for professional check engine light diagnostics.
