SOURCE: getting an error code of PO449 for a check engine

You are right. You need the vent valve not the purge valve. The vent valve is a dealer item. Also this is a common problem and GM has released a bulletin on this that involves moving the location of the valve and running some new lines. It comes as a kit from GM, and it costs about a 100 bucks.

SOURCE: 1997 malibu / I had faulty code po440 . I Replaced Purge valve behind engine, canister valve solenoid, gascap from dealer, charcoal canister, smoke test. 1 week later check engine light on again wit

Diagnostib Test Code (DTC) P0440 is defined by SAE J2012 simply as "Evaporative Emission System".

This code is what I call a "catch-all" code for the evap system. This is the code that sets when all the other EVAP codes do not apply and there is a malfunction detected in the EVAP system.

It is not really hard to diagnose this code if you have the correct equipment and understand how the EVAP system operates.

How DTC P0440 sets:

The system is tested when there are no electrical problems with the Purge Control Solenoid Valve (PCSV) or Canister Vent Solenoid Valve (CVSV) circuits and the Fuel Tank Pressure (FTP) sensor voltage is within the operating parameters. The Powertrain Control Module (PCM) commands the CVSV to close and the PCSV to open and apply vacuum. It then looks for a change in the FTP voltage to indicate that there is a vacuum being drawn on the fuel tank. If there is no change, DTC P0440 sets.
If there is a change in FTP voltage, the PCM draws the vacuum to a predetermined set point and closes the PCSV (leaving the CVSV also closed) and looks for decay in the vacuum in the tank as evidenced by the FTP voltage. If the predetermined set point cannot be reached, DTC P0440 sets. If the set point is reached and the decay is faster than allowed over a predetermined time period, DTC P0440 sets.

It should also be noted that the monitor for this code is a "type B" DTC, meaning that it must fail on two successive drive cycles before it will turn the check engine light on. So, if it fails on the current drive cycle, then the conditions for running the monitor are not met on the next drive cycle, the code will not set on the second or third drive cycles. All conditions must be met and the monitor must fail two drive cycles in a row. This explains why it may take a week or two before the check engine light comes back on.

This code is very easy to diagnose using a scan tool that is capable of performing "purge and seal" tests and graphing the FTP voltage over time. The technician can actually "see" the vacuum being drawn on the fuel tank and the vacuum decay by doing it this way. Repairs can be verified this way without having to drive the vehicle several times to get the EVAP monitor to run.

By running the evap purge/seal function on the scan tool and using hose clamping pliers, different parts of the system can be checked by clamping off the hoses that connect the components and watching the FTP voltage graph. If there is no change in the FTP voltage when the system is commanded to purge, a vaccum gauge should be used to verify that the purge solenoid is actually working and that vacuum is being applied to the rear of the vehicle There could be leaks in the line between the purge solenoid and the canister.

For an example of how this works:

Possible rust holes in the filler neck and/or a defective fuel cap can be determined if there is no change in the FTP sensor voltage or rapid decay upon the initial test that goes away when the filler tube hose is clamped off between the filler tube and the fuel tank. A sticking CVSV can be determined in the same fashion by clamping off the hose between the charcoal canister and the CVSV.

Holes in the hoses themselves can also be diagnosed the same way by disconnecting them from the vacuum source end and plugging the source tube. Example, remove the vent hose from the canister and plug the hole in the canister. If the problem goes away, it is either the hose leaking or the CVSV leaking. So, reconnecting the hose to the canister and disconnecting it from the CVSV and plugging the end of the hose will tell you if it is the hose or a sticking CVSV.

This may sound really involved, but it is very easy to diagnose this way once you know how.

2007. What are the probable causes of DTC P0446?


DTC P0446: Evaporative Emissions (EVAP) Vent System Performance
Circuit/System Description
This DTC tests the evaporative emission (EVAP) system for a restricted or blocked EVAP vent path. The control module commands the EVAP canister purge solenoid valve Open and the EVAP canister vent solenoid valve Closed. This allows vacuum to be applied to the EVAP system. Once a calibrated vacuum level has been reached, the control module commands the EVAP canister purge solenoid valve Closed and the EVAP canister vent solenoid valve Open. The control module monitors the fuel tank pressure (FTP) sensor for a decrease in vacuum. If the vacuum does not decrease to near 0 inch H2O in a calibrated time, this DTC sets.
Diagnostic Aids
?€¢
An intermittent condition could be caused by a damaged EVAP vent housing, a temporary blockage at the EVAP canister vent solenoid valve inlet, or a pinched vent hose. A blockage in the vent system will also cause a poor fuel fill problem.


?€¢
An EVAP canister, vent hose, or vent solenoid valve that has restricted flow may cause this DTC to set. Using a purge solenoid command with a scan tool will allow vacuum to be applied to the system instead of pressure. With the engine running, the EVAP canister vent solenoid valve open, and the EVAP canister purge solenoid valve commanded to 100 percent, the fuel tank vacuum should not increase to more than 5 inches H2O.


?€¢
An EVAP canister filter that is restricted can cause this DTC to set. Refer to Evaporative Emission Canister Replacement .


?€¢
Disconnecting one component at a time while the EVAP system is under flow will help to pinpoint a restriction in the system


Do you have a scan tool that reads data PID'S ?
Your FTP - fuel tank pressure sensor could be at fault !

    Ignition ON and fuel cap removed, verify that the FTP sensor parameter is between 1.3-1.7 volts. ?‡'
    If not within the specified range, go to the FTP sensor section in Circuit/System Testing.

  1. Install the fuel cap.
  2. With the engine running, the EVAP canister vent solenoid valve open, and the EVAP canister purge solenoid valve commanded to 100 percent, the fuel tank vacuum should not increase to more than 12 inches H2O.
?‡'
If the fuel tank vacuum is greater than the specified range, go to the restriction section in Circuit/System Testing.

My 2005 Pontiac G6 has the check engine light on and I was told it was the vent solenoid. Where is this on the car and is it hard to replace yourself?


Hi, the vent solenoid is next to the vapor canister by the fuel tank. It has one hose connected to the top of the tank and one connected to the canister. I have pasted a pic of the vent valve below.

P1443 code problem. How do I fix this?


P1446 - EVAP Canister Vent Control Valve Close
EVAP canister vent control valve remains closed under specified driving conditions.

This solenoid valve responds to signals from the ECM. When the ECM sends an ON signal, the coil in the solenoid valve is energized. A plunger will then move to seal the canister vent. The ability to seal the vent is necessary for the on board diagnosis of other evaporative emission control system components.

This solenoid valve is used only for diagnosis, and usually remains opened. When the vent is closed, under normal purge conditions, the evaporative emission control system is depressurized and allows EVAP Control System (Small Leak) diagnosis.

The EVAP canister vent control valve is located on the EVAP canister and is used to seal the canister vent.

Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)

About the possible causes that your must solved:
- EVAP control system pressure sensor and the circuit
- Blocked rubber tube to EVAP canister vent control valve
- EVAP canister vent control valve
- Water separator
- EVAP canister is saturated with water


Hope this helps.

Hi my 2005 Chevrolet Tahoe seems to have a blocked fuel vent .When I try to fill it I can hear a whistling and the fuel keeps backing up in the filler neck . Do yoy have any drawings for the routing or...



There may be a problem with your EVAP system.Dirt/dust can get into the system causing a poor fill condition.Replacement of EVAP canister and or vent solenoid may be required.
The canister and vent solenoid are located near the gas tank on the passenger side under the vehicle.


• Fuel fill limiter vent valve stuck closed • Evaporative emission (EVAP) canister restricted • EVAP vent valve stuck closed • Hose between canister and canister vent solenoid twisted or kinked if applicable • High fuel temperature • Fuel filler hose is kinked
