Abstract

Error code P0496 indicates your vehicle's EVAP (Evaporative Emission Control) system is experiencing high purge flow, meaning too much fuel vapor is being drawn from the charcoal canister into the engine. This typically points to a stuck-open purge valve or faulty wiring, and while not immediately dangerous, it can affect fuel economy and emissions compliance.
