Question about Buick Park Avenue

1 Answer

Failed the emissions test (Il..) code came up P1441. After researching code translatons it means: evaporative emission system flow during non- purge. I called advanced auto parts( because that or any code means a part is failing, according to the emissions tech(?) who gives the test) to buy the part. The part man said it could be any part in the evaporative emissions path/circuit ie: gas cap, ____?stuck open, broken vacuum hose, vapor cannister,etc. I thought I 'd get a schematic of the system and try to follow the path to see if I could spot a split in a line,anything disconnected, anything loose etc. Anyway those are my emission problems with my car...thanks for any help I may get!

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

P0441 what dose it mean and how can I fix it .toyota camery le 1998model


P0441 1998 Toyota Camry - Evaporative Emission Control System Incorrect Purge Flow

When is the code detected? Pressure in charcoal canister and fuel tank does not drop during purge control (2 trip detection logic).

Possible symptoms: - Engine Light ON (or Service Engine Soon Warning Light)
- Possible a noticeable fuel odor caused by the release of fuel vapors

P0441 1998 Toyota Camry Description: The Engine Control Module (ECM) tests the Evaporative Emission (EVAP) system for the following conditions:
- Large and small leaks

- 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.

P0441 1998 Toyota Camry Evaporative Emission Control System Incorrect...

Possible causes - Missing Fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- Incorrect fuel tank vacuum relief valve

Definition of po1441 trouble code


P1441 Evaporative emission control system very small leak, positive pressure.
The problem may be that the purge control valve which is part of the charcoal canister has a slight leak.
If the control valve doesn't completely close, there will be flow during non-purge.
Vacuum drawn through the small hose to the charcoal canister is what opens the purge control valve.
Make sure that there is no vacuum to the smallest hose connected to the canister at idle.
Make sure the little hose is not kinked or pinched in some way that would hold vacuum to the purge control valve.
The canister is purged above 35 MPH, never at idle.

P0446 EVAP canister vent valve

The P1441 and P0446 are related.
When you fix the P1441 the P0446 may go away also or it may need a new vent valve.

Two choice dudes code there...

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
  • Replace PCM


DTC P1441 - Evaporative Emission (EVAP) System Flow During Non-Purge.
M
ost 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.


Hope this helps.

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.


Here's a link to codes and what they mean http://autorepair.about.com/cs/troubleshooting/l/bl_obd_main.htm

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

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.
