What does the DTC code p0411 stand for?

Diagnostic trouble code (DTC) P0411 stands for “Evaporative Emission Control System (EVAP) Incorrect Purge Flow.” Your car’s computer will set the code when it determines there’s an improper amount of fuel vapor being “purged” from the EVAP charcoal canister into the engine.

What causes the EVAP purge solenoid to be off?

The ECM commands the EVAP Purge Solenoid OFF once the system has reached a predetermined level of vacuum. This test verifies if a vacuum can be achieved in the EVAP system. Failure to develop a vacuum may be caused by a large leak or a restriction.
