SOURCE: I have a 2004 Avalanche, 49K mileage, code PO446,

That is an EVAP code. its a vent control code. you can manually test it by powering it up if you know where its at. i cant remember exaclty where its at off the top of my head but its only 2 wires. using a volt meter you want to make sure power is getting to it, but you cannot activate it without dealer scan tool.hmmm if you can figure out which is ground and power when you give it 12 volts it should click. meaning your vent solenoid works and you have wiring problems or its leaking.

EVAP problems are hard to finde with out scanners. you can change the vent solenoid and hope it fixes it. but a code points you to the direction of a problem. hopefull its not wiring problems. in the northern states with snow. ice can pull out wires and also get clogged in the vent solenoid and lock it up. its either wiring or bad or a leaking solenoid. check condition of wires. if they look good try a vent soleniod.

if that doesnt fix it after a engine light reset and 2 weeks or so. then goto dealer. you need to reset it after repair. light will not go off on its own.GOOD LUCK

The evap purge solenoid is located on the intake manifold. The evap vent valve is located on the side of the fuel tank. If you have a P0449 or P0452 (I think) DTC, it will be the one on the tank that you need to replace.

in my experience the usual culprit is the evap cannister. the problem is it gets moisture in it and freezes during winter thus cracking the plastic. if you lay under the car and look at the evap box it black plastic and if you see a loose or cracked hose or the box itself is cracked that is most likely it. as a side note you can check the gas cap and buy a new one to see if that rectifies the situation. lastly i don't think the gas tank should be suspect as you would probably notice if gas was leaking out of the tank. if you take the car to a dealer or shop they can do a smoke test and determine where the leak is.

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.

Were is the EVAP System vale on Honda odyssey 2003

This code indicates a leak in the evap system. The first thing to check is the gas cap-is it on tight? If yes, check vacuum hoses under the hood. A loose or degraded hose on the purge valve will also cause this code. The purge valve looks like the pic below and has one hose going to the engine and the other going to the vapor cannister.

When Engine light came on 2009 Mercury Sable and got P0442 diagnostic code so how bad is diagnostic and how costly to fix?

code p0442 refers to evaporative emission system(EVAP)--small leak detected==causes-- hose connections,--intake leak--EVAP canister--EVAP canister purge valve
it also refers to large leak detected ( loose fuel cap/missing cap) causes--mechanical fault--hose connections---EVAP pressure sensor
If it has just started then check that the fuel cap is on tight or replace the pressure sensor or lastly ( it will probably the most expensive) the purge valve.

Have a p0441 on my mitsubishi galant 2.4v

Hi there:DTC P0441 - Evaporative Emission Control System Incorrect Purge FlowThis 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.
Likely, no symptoms will be discernible to the driver, other than the illuminated Check Engine Light.

A code P0441 could mean one or more of the following has happened:Bad vacuum switchBroken or damaged EVAP line or canisterOpen in PCM purge command circuitOpen or short in Voltage feed circuit to Purge SolenoidFaulty purge solenoidRestriction in EVAP solenoid, line or canisterCorrosion or resistance in purge connectorBad 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 / LDPRepair damaged EVAP lines or canisterRepair open or short in voltage feed circuit to Purge SolenoidRepair open in PCM purge command circuitReplace purge SolenoidReplace vacuum switchRepair restriction in Evap line or canister or soleniodRepair resistance in purge connectorReplace PCM
Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.
Thank you for using FixYa, have a nice day.

This DTC tests for undesired intake manifold vacuum flow to the evaporative emission (EVAP) system. The control module seals the EVAP system by commanding the EVAP purge valve OFF, closed, and the EVAP vent valve ON, closed. The control module monitors the fuel tank pressure (FTP) sensor to determine if a vacuum is being drawn on the EVAP system. If the vacuum in the EVAP system is more than a predetermined value within a predetermined time, DTC P1441 will set.

Check The Evap purge valve for leakage.

I have a 2007 chevrolet tahoe and code is Po 496.

this is an evap emissions code dealing with a bad evap canister purge valve or purge valve solenoid. To test for these most mechanics will use a smoke test to find where the leak (if any) is located.

Po446 evap vent code where is the evap vent located

Some might have an ses p0446, evap emissions vent circuit low. If you take it to the dealer they want 300-400.00 to fix the problem. GM has a service bulletin on this condition and have the updated part for 180.00, thats suppose to eliminate this issue.

Basically the problem is, the evap purge vent valve gets clogged with dirt, especially if the truck is used in dirty conditions. Well I figured there had to be a cheaper way to cure this problem.

Here it is:
1) find the location of the vent valve; its under the truck, locate the charcoal canister on the front of the gas tank and trace the vent line to the vent valve.
2) Take the bracket loose with a 5/8 wrench.
3) Spin the valve around so the side with the hole is facing you.
4) Take an air compressor and blow the vent valve out.
5) reinstall and clear the code and it's fixed.

Now I know the updated part from gm is supposed to keep the valve from clogging ever again, but why spend the money when all you have to do is blow out the vent valve every 50k-100kmi and save your $$$!
