I keep get a check engine light a p1441 that says system flow during non purge; i fixed a cracked line to the purge selonoid from the throttle plate ,put a used sensor on the canister under the ecm ,put a a new gas tank in the car because of a pinhole in the tank and when i did that i put in a new vapor sensor to be safe and also tried a used purge selonoid on the engine but to no success after clearing the codes after each attempt it still comes back on when the monitors kick in a couple days later. so what am i missing? thanks

P1441 CHEVROLET Description
The Engine Control Module (ECM) has detected vacuum flow to the Fuel Tank Pressure (FTP) sensor during a system sealed condition. Possible causes are a faulty canister purge solenoid or a faulty tank pressure sensor.
DTC P0441 - Evaporative Emission (EVAP) Control System Incorrect Purge Flow EVAP emission canister purge is contolled 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. With a P0441 OBD-II trouble code, diagnosis can be tricky at times. Here
are some things to try:
Common Chrysler fix - Replace Leak Detection Pump / LDP
Repair damaged EVAP lines or canister
Repair open or short in voltage feed circuit to Purge Solenoid
Repair open in PCM purge command circuit
Replace purge Solenoid
Replace vacuum switch
Repair restriction in Evap line or canister or soleniod
Repair resistance in purge connector
DTC P1441 - Evaporative Emission (EVAP) System Flow During Non-Purge. Most generally caused by a purge valve stuck open. the only way to diag for sure is with a gm tech 2 scan tool and a smoke machine. but if dont mind spending a few bucks as a good quess. Replace the purge valve.
CODE P1441 -- EVAP SYSTEM FLOW DURING NON PURGE CONDITIONS. POSSIBLE CAUSES. EVAP PURGE VALVE PIPE OR THE CHARCOAL CANISTER HAS A TEMPORARY BLOCKAGE. FTP SENSOR IS OUT OF CALIBRATION DAMAGED OR IT IS SKEWED. EVAP PURGE SOLENOID VALVE IS DAMAGED OR HAS FAILED. PCM HAS FAILED.
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.
Here's a link to codes and what they mean http://autorepair.about.com/cs/troubleshooting/l/bl_obd_main.htm
This is the OBD II code to indicate EVAP system flow during non-purge. Sometimes this is caused by not completely screwing in the fuel cap. Reset the code (or have it reset), and be sure to always fully tighten the fuel cap. If the problem persists it is caused by a leak in the fuel tank or line. Check the following:
P1442 usually gas cap. P1449 usually vent solenoid. P1441 usually always a faulty FTP sensor. Very problematic to Malibu, Grand Am Cavaliers and Aleros. That would be my first area to check. They are also known for poor wiring connections at the Left rear passthru connector to the fuel tank and vent solenoid, but not necessarily for that code.
A P0300 DTC is a misfire code. The P1441 is a no flow during purge code which has to do with the purge solenoid. With the misfire code present I would say you have a vacuum leak on one of the hoses. The purge solenoid is located in the passenger side, rear of the intake manifold.
P1441 Evaporative Emission (EVAP) System Flow During Non-Purge The evap system is your egr valve, carbon canister, pcv valve, gas cap, and fuel tank vent, The most common fix for this problem is a new gas cap and then your done. It is about 15 dollars and then you pass smog. If this has been of any help please reate. Thank you
code is evap system flow during non-purge
check the hoses for holes or broken disconnected hoses also check the fuel cap emissions diagram under the hood will give u the location of the evep purge solenoid if all checks ok then replace the soienoid and clear the codes
rank & vote my solution
P1441, EVAP Emissions System Flow During Non-Purge.
you seem to have an evap problem these problems are hard to diagnose sometimes it can only be the gas cap or maybe rust around the seat of the gaz cap
get the code erase and see if it comes back on and if it does check gas cap and arroung the filling neck if there is rust if no visible rust apears you will have to get it check with smoke to see where it leaks
