EVAP Vent valve, purge valve what ever the P0446 obd code is refering to, where is it located on a 2004 Santa Fe with the 2.4L engine? Is it under the hood in the engine compartment or in rear of vehi

Seems as though engine is burning oil, oil level is low and no leaks under the vehicle or on exhaust system(being burned up externally). Also the check engine light came on, found two codes P0446 and P0421. 421 out board o2 sensor catalytic converter efficeincy below threshold possibly due to being overworked with burned oil exhaust gases, just guessing.

SOURCE: Check Engine light - Code P0441 (Evap Emission

There is an evap purge valve located in the back of the driver side of the engine. This valve needs to be replaced. Had the same code a couple weeks ago. Replaced that valve and the problem was fixed. Hope this helps.

If you live in the US, take it to qany Auto Zone store and thy will read the codes off for you, I would suspect any right thinking competitor would do the same, check if you don't have one near by.

Hope this is of some help.

I have a book for the Sante Fe, and that code is not in it. I would go back to them and have them re-run it. The person may have just misread the screen.

Code P0446


Yes. it will trigger the code as the fuel system has to be sealed for everything to work. code p0446 refers to ( EVAP) evaporative emission system vent control-circuit malfunction==causes --wiring--EVAP canister purge valve--ecm . The leak will upset the purge valve. You will have to come back with the other codes as there are some 1900 codes to go through in the OBD-11 tables.

Hi there:

A code P0446 could mean one or more of the following has happened:
- Faulty vent valve
- Open, short or excessive resistance on Vent valve control circuit
- Blockage of vent valve
- Bad PCM




With a P0446 OBD-II trouble code, here are some things to try:
- Replace Vent valve
- Repair open, short, or resistance problem in control circuit
- Repair open, or short, or resistance problem in power circuit

- Replace PCM




Hope this helps.

P0446 code on a 2004 ford expedition 5.4


P0446 - Evaporative Emission Control System Vent Control Circuit Malfunction

Evap vent valve has only one purpose. It closes in order to seal the vent so the EVAP system can pressurize and ensure there are no leaks. Evap vent valve is usually supplied Batt. voltage with key on. The ECM's driver controls the ground, and when grounded, activates the valve (closing it). If the ECM detects a short to ground, and open,or a short to battery voltage on the control circuit, P0446 will set. Code also may refer to ECM detecting that EVAP system is unable to achieve or maintain vacuum during test.

Symptoms: There will be no obvious symptoms to driver, other than MIL illumination.

Causes: A code P0446 could mean one or more of the following has happened:
* Faulty vent valve
* Open, short or excessive resistance on Vent valve control circuit
* Blockage of vent valve
* Bad PCM

Possible Solutions: With a P0446 OBD-II trouble code, here are some things to try:
* Replace Vent valve
* Repair open, short, or resistance problem in control circuit
* Repair open, or short, or resistance problem in power circuit
* Replace PCM

I hope help with this (remember to rate and comment this).

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 $$$!
