[McCharles]

eobd fault warning light is generally caused by system failures, such as poor contact in car wiring, EGR valve blockage, excessive emissions, or sensor malfunctions. Below is information about the eobd fault warning light: 1. The eobd fault warning light is part of the on-board diagnostic technology, abbreviated as OBD. EOBD is also referred to as OBD. 2. All vehicles must be equipped with an OBD system, which is designed, manufactured, and installed to ensure the vehicle can identify degradation types and fault types. 3. The OBD system continuously monitors the engine's operating conditions to check if the vehicle's emissions exceed standards. If they do, it immediately issues a warning. Therefore, when the OBD fault light comes on, it indicates an emission-related fault in the vehicle. 4. The illumination of the fault light generally indicates the presence of a fault. It is necessary to check the wiring, EGR valve, and vacuum regulator valve connections for issues, or whether a sensor has malfunctioned.
