- Excess vacuum
- Purge flow during non-commanded conditions
- Fuel Level and Fuel Pressure sensor faults
- EVAP Purge and Vent Valve faults
The ECM monitors the Fuel Tank Pressure sensor in order to determine the level of vacuum/pressure in the EVAP system. The ECM commands both the EVAP Purge Solenoid and the EVAP Vent Valve ON when the conditions are met in order to apply an engine vacuum to the EVAP system. 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.

P1441 Evaporative Emission System Flow During Non-Purge.
The vacuum system/Evaporative recovery system. Evap. (vapor cannister) code MAY be as a result of excessive fuel flow into the cylinders overloading the cannister's capacity. Possible cause is a failing Oxygen sensor giving a "Lean" indication to the engine computer, causing more fuel than is needed to be injected into the cylinders and captured by the vapor system. Trying to keep track of the changing readings may be taxing the computer's memory. Have the oxygen sensor checked. If it is functioning correctly, check for vacuum leaks, cracked or broken vacuum hoses.
Take you car to a professional as this is going to take some skill and knowledge to repair. Dont keep buying parts to fix the problem as this will get very expensive.
