I have checked the vacuum lines foe leaks and for 12v at the purge valve. I have checked the purge valve for operation on the bench also the vacuum operated valve at the canister. What else could be causing this code?

Evaporative Emission Control System Incorrect Purge Flow
What does that mean?
This indicates that a part of the EVAP control system is no longer functioning correctly. The EVAP system consists of many parts, including (but not limited to) the gas cap, fuel lines, carbon canister, purge valve, and other hoses. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.
EVAP emission canister purge is controlled by a valve which allows engine vacuum to pull stored fuel vapors from fuel tank into the engine to be burned, rather than be vented to atmosphere. A vacuum switch is used to detect when flow exists. If the PCM commands purge and sees that the switch is closed (indicating no detected purge flow) P0441 is set.
Symptoms
Likely, no symptoms will be discernible to the driver, other than the illuminated Check Engine Light.
Causes
A code P0441 could mean one or more of the following has happened:
With a P0441 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:
