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

hope it will help you

Have a great day

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

ok looking for evap leaks are sometimes hard a vary small leak will cause you grief you can try to pressure up your fuel system with air hose to fuel filler opening 3 psi max , don't blow your self up , get a garden sprayer and dish soap with water and start spraying down the evap system look for bubbles and fix the leak

Where is the vacuum cut valve located,,, the code reads p1441 what to fix it or replace it my self.....


I just found the answer that
The vacuun cut bypass valves I deal with are in the evap emissions hoses near the charcoal canister valve is white in color and have no electrical connections just (4) 5/8" vacuum lines. Two of those hoses go to a solonid valve with a two wire electrical connection. Gasoline in the signal hoses from over filling the tank can cause the tank pressure sensor to send the wrong evap emission information to the Engine computer that in turn sets the P1441 code. Those hoses are on the filler neck to the gas tank pull them off one at a time and see if one has about 1 oz of fuel in the rubber hose (no smoking). Good luck for you!

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.

Diagnostic code p1441 and p1406 fir 96 camaro WHATS THAT MEAN


Here's the description for the DTC P1406: The PCM monitors the EGR valve pintle position input to ensure that the valve responds properly to commands from the PCM and to detect a malfunction if the pintle position sensor and control circuits are open or shorted. If the PCM detects a pintle position signal voltage outside the normal range of the pintle position sensor, or a signal voltage that is not within a tolerance considered acceptable for proper EGR system operation, the PCM will set DTC P1406.

That means there is possibly a problem within the EGR valve itself, or a wiring/connector related to the EGR valve. Having a scan tool to command the EGR valve and watch the data would be extremely helpful in diagnosing this code.

Here's the description for DTC P1441:
The EVAP vacuum switch is a normally closed switch positioned in the purge line between the canister and the EVAP purge valve. The EVAP vacuum switch will open when vacuum increases to greater than 5 inches of water (in H2O) in the purge line. The PCM monitors the EVAP vacuum switch signal to determine if the evaporative emission control system is working properly. If the switch is open (purge flow detected) when the PCM is not commanding the EVAP purge valve ON, DTC P1441 will be set.

Again, this code would be best diagnosed with a scan tool that can command the purge valve and allow you to watch the data related to it. Check your vacuum lines and electrical connections to the purge vacuum switch. If the vacuum switch is unplugged this code can set.

Wont start and trouble code is p1441


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.

Imisions test comes back with, code P1441 ?


P1441 is a EVAP code, small leak I thinking.

P1441 Evaporative Emission (EVAP) System Flow During Non-Purge

Now for the fix: the ECM uses a pressure sensor to watch the system and see that there are no leaks. If it sees a leak via the pressure sensor, it sets this code. The ECM wants to see the pressure sensor voltage drop down, indicating that there is vacuum on the system, and it wants it to be able to hold this vacuum for at least 30 seconds. If this does not happen, it will set a code. As a note, the vent solenoid is the most common failure on these systems.

Hope helps (remember to rate and comment this).

Advanced auto checked my car and the code comes up "p1441" "dealer" yet no one will or can tell me what it means


The biggest reason for this is that many of the codes are universal to all cars but when they come up as dealer the manufacturer set the parameter for this code. This code for a on several models P1441 - Evaporative Emission (EVAP) System Flow During Non-Purge The purge valve may be stuck open allow it to purge even when it should not be. I will see if I can find anything else on this for you.
