What is the P0496 fault in the Emgrand Binyue?
2 Answers
Emgrand Binyue P0496 trouble code, applicable to all automobile manufacturers, means high purge flow rate in the evaporative emission system. Trouble code meaning: The evaporative emission system directs fuel vapors from the fuel tank into a canister containing activated charcoal that can absorb the fuel vapors. The engine then uses fresh air to purge these fuel vapors into the engine combustion chamber. This trouble code indicates that the purge flow rate in the evaporative emission system is too high. Trouble code clearing: After troubleshooting the vehicle, the trouble code needs to be cleared. When clearing the code, it must be done according to the specified method for the corresponding vehicle model. It is absolutely not permissible to randomly use the method of disconnecting the negative terminal of the battery to clear the trouble code.
During my research on automotive trouble codes, I encountered numerous issues related to P0496. This specific code indicates abnormal flow in the evaporative emission control system under high-load conditions. Simply put, it means the vehicle's emission control system exhibits excessive airflow during acceleration or hill-climbing scenarios. Common causes observed in the Geely Binyue include carbon canister clogging, stuck vent valves, or minor pipeline leaks. If left unaddressed, this may lead to emission exceedances affecting environmental inspections, and even slightly increased fuel consumption. I recommend immediately using a diagnostic tool to read data streams for pinpointing faulty components, while simultaneously inspecting fuel tank and hose connections. Regular maintenance involving carbon canister cleaning can prevent such issues, ensuring stable overall vehicle performance.
