Code P0441 Honda Description

The fuel vapor in the fuel tank is temporarily stored in the Evaporative Emission (EVAP) canister and drawn into the engine through the EVAP canister purge valve. The Powertrain Control Module (PCM) controls the amount of vapor introduced into the engine by varying the duty cycle of the EVAP canister purge valve according to the condition of the engine.
The PCM checks the purge flow conditions on both negative and boost pressure sides. If either side of the purge flow is detected as abnormal, it is determined that there is a clog or disconnection on the abnormal side of the purge line. If both sides of the purge flow are detected as abnormal, it is determined that the purge lines are abnormal, or the EVAP canister purge valve is stuck open.
