Question about Chrysler Sebring

1 Answer

My 2002 Chrysler Sebring coupe with a 3.0 V6 has two error codes, PO441 (EVAP Emission Control System Purge Flow Fault) and P0455 (EVAP Emission Control System Leak [Large]) This has been a somewhat intermittent problem for quite some time. What may or may not be related, is that on a few occassions I had trouble fueling the vehicle becuase the automatic shutoff on the fueling nozzel kept kicking off unless I ran the fuel in very slowly so the air could escape the tank through the fill pipe.

The PCM EVAP monitor detected no air flow through the EVAP system.
Inspect for plugged hoses from the solenoid to charcoal canister or from solenoid to t-body and for cut or cracked hoses.
the way the evap system works is that when your vehicle sits fuel vapors have to go somewhere so rather than emitting them to the atmosphere they are routed via hoses to a charcoal canister which acts like a sponge and stores these vapors,when you start up you vehicle a solenoid allows engine vacuum to absorb those through a series of hoses and burn them away,this also happens when you're driving and the gas sloshing around in your tank creates more fumes and pressure this solenoid opens up again allowing engine to burn off those vapors.so when you start your car a monitor or sensor monitors this routine so if there is restriction or a broken hose there is no airflow.
----------- When you have an emissions control system leak on your car it is very important to have this malfunction repaired as soon as possible. If your emissions control system leaks dont ignore it. An emissions control system leak can be as simple as a loose or detached vacuum line or it may be as advanced as a computer malfunction. You may have a hole in, blockage of or cracked catalytic converter. Maybe you EGR or PCV valve is broken, loose, partially or completely detached. Your evaporative emissions control system may need repaired or replaced. It is even possible that an oxygen sensor on your exhaust may need replaced or your oxygen injection system is in need of repairs. If you have an emissions control system leak caused by the vacuum controls related to your emissions control system then all you have to do is have a trained automotive repair prfessional trouble shoot your cars vacuum system. If you have an emissions control system leak of your catalytic converter or EGR valve, you can have any of these repairs performed simply by any certified and licensed automotive exhaust professional. If your PCV valve is broken or malfunctioning, any general automotive repair facility along with many oil change facilities can and will replace your PCV valve for you. If you have a broken or malfunctioning oxygen sensor, you will need to have your cars emissions control system leak caused by the failure of the oxygen sensor repaired by a facility that is licensed and certified by your cars manufacturer.


If you do not diagnose and repair any emissions control system leak on your car it can and normally will cause other parts and systems on your car to begin to malfunction and eventually fail on some level.
And yes both the above mentioned error are related to each other.and this errors cause problem in fuel .As the fuel pressure needs to be checked .
Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.

P0449 and P0455 error code 2008 2wd gmc envoy 30,203 miles


P0449 - Evaporative Emission Control System Vent Valve/Solenoid Circuit Malfunction

P0455 - Evaporative Emission Control System Leak Detected (no purge flow or large leak)

Both are refer at EVAP system; other EVAP DTCs: P0440 - P0441 - P0442 - P0443 - P0446 - P0453 - P0455 - P0456

This indicates a fuel vapor leak or lack of purge flow in the EVAP control system. It means a large leak has been detected. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.

Symptoms: You likely won't notice any drivability problems.
Causes: most likely means one or more of the following has happened:
A loose or improperly affixed gas cap
A non-conforming gas cap (i.e. not factory/original brand)
Other leak or damaged piece in EVAP system

Possible Solutions: the most common repair is to:
Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
Otherwise, replace the gas cap, and/or
Inspect the EVAP system for cuts/holes in tubes/hoses (you may hear a vacuum noise or smell fuel), repair if necessary


Hope helps.

I'm receiving an Error code po441, I took it to the dealer who replaced the EGR valve and reset the engine light and cleared codes a week ago, now my engine light just came back on with same code


Some dealer you got there

PO441-EVAP System --Incorrect Purge Flow

They may have found an EGR Valve issue,
but they certainly blew off the EVAP Code

I would guess you have a bad EVAP Canister
Purge Valve or some other purge control

P0441 Evaporative Emission Control System Incorrect Purge Flow
OBD-II Trouble Code Technical Description

Evaporative Emission Control System Incorrect Purge Flow
What does that mean?

This indicates that a part of the EVAP control system is no longer fuctioning correctly. The EVAP system consists of many parts, including (but not limited to) the gas cap, fuel lines, carbon canister, purge valve, and other hoses. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.

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.
Symptoms

Likely, no symptoms will be discernible to the driver, other than the illuminated Check Engine Light.
Causes

A code P0441 could mean one or more of the following has happened:

* Bad vacuum switch
* Broken or damaged EVAP line or canister
* Open in PCM purge command circuit
* Open or short in Voltage feed circuit to Purge Solenoid
* Faulty purge solenoid
* Restriction in EVAP solenoid, line or canister
* Corrosion or resistance in purge connector
* Bad PCM

Possible Solutions

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
THIS IS LIKELY FROM TOPPING OFF THE TANK EACH TIME YOU FUEL UP



P0455 is similar:

Technical Description

Evaporative Emission Control System Leak Detected (no purge flow or large leak)
What does that mean?

This indicates a fuel vapor leak or lack of purge flow in the EVAP control system. It means a large leak has been detected. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.
Symptoms

You likely won't notice any drivability problems.
Causes

A code p0455 most likely means one or more of the following has happened:

* A loose or improperly affixed gas cap
* A non-conforming gas cap (i.e. not factory/original brand)
* Other leak or damaged piece in EVAP system

Possible Solutions

With a p0455, the most common repair is to:

* Remove and reinstall the gas cap, have AutoZone clear the codes, and drive for a day and see if the codes come back.
* Otherwise, replace the gas cap, and/or
* Inspect the EVAP system for cuts/holes in tubes/hoses (you may hear a vacuum noise or smell fuel), repair if necessary
