P0441 Evaporative Emission System Incorrect Purge Flow

General Information

General Description

The Evaporative Emission Control System (EVAP) prevents hydrocarbon (HC) vapors in the fuel tank from escaping into the atmosphere where they could form photochemical smog. Gasoline vapors are collected in the charcoal canister. The Purge Control Solenoid Valve (PCSV) is actuated (duty cycled) by the Powertrain Control Module (PCM) to control vapor flow from the canister to the intake manifold.

DTC Description

Checking output signals from fuel tank pressure sensor under evap. system test, if fuel tank's vacuum is higher than prescribed threshold, PCM sets P0441.
