DTC P0446 Evaporative Emission (EVAP) Vent System Performance

The vehicle control module (VCM) monitors the performance of the evaporative emission (EVAP) system by applying a predetermined level of vacuum to the EVAP system and monitors the vacuum decay rate. The VCM sets this diagnostic trouble code (DTC) if the vacuum decay rate is more than a predetermined value. The VCM monitors the amount of vacuum and the amount of pressure in the EVAP system by monitoring the fuel tank pressure sensor. For this DTC, the VCM turns ON both the EVAP purge valve and the EVAP vent valve when the Conditions for Running the DTC are met. This applies an engine vacuum to a closed EVAP system. The VCM turns OFF both the EVAP purge valve and the EVAP vent valve when the system reaches a correct amount of vacuum. The EVAP system should quickly RELEASE the vacuum in the EVAP system with the EVAP purge valve OFF and the EVAP vent valve OFF (open). This test indicates a blocked or restricted EVAP vent path if the EVAP system fails to release the vacuum quickly enough.

SOURCE: purge solenoid location

which vehicle are you actually looking for the purge solenoid on? you have 2 vehicles listed in your question. i'll answer both, lol

the locations are described as if you are looking at the engine from the front of the car with hood open.

on the blazer:

it is located on the left side of the intake manifold just under and behind the throttlebody. it is a canister looking device.

on the silverado:

it is located on the intake manifold on the left side in about the same spot as the blazer. providing the silverado has the 5.3 or 5.7 liter engine. if it also has the 4.3 then obviously it will be the same.

hope this helps!

SOURCE: 2007 SILVERADO V6 EVAP PURGE SOLENOID

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.

Where is the evap vent solenoid fuse located on 2005 nissan altima


It doesn't have a "fuse" specific to the purge valve solenoid. What he is telling you is that you need to have this circuit troubleshot. Either the PCM the wiring going to the purge valve solenoid, or the purge valve solenoid itself is malfunctioning.

This requires a scanner, a digital volt ohm meter and some knowledge of when the purge valve actuates and under what conditions.

The car must be running and operating at cruising speed before the PCM sends a command to the purge valve to operate. Some scanners have the ability to send a request to the PCM to actuate the purge valve, but that scanner is usually a dealer's or equivalent.

Getting an error code of PO449 for a check engine light. this says it is the Evaporative Emissions Control System Vent Valve/Solenoid Circuit Malfunction. I keep looking for a replacement part of the vent...


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.

Code 449? what is this,anyone. tks


Code po449 is for bad  solenoid vent valve.After replacing the valve  check for the   12 volts at the "pink" wire.
This error relates too 

The PCM has determined that a malfunction exists in the electrical circuit for the vent valve/solenoid in the evaporative emission control system.

Definition:
EVAP (Evaporative Emission System) purge/vent solenoid circuit condition

Explanation:
The solenoids and system wiring are monitored for opens or shorts

Probable Causes
1- Purge or vent solenoids defective.
2- Check connector and wiring.
3- Fuel saturated vapor canister.
4- Failed EVAP vent solenoid.


 --------

The cost of the vent solenoid valve is near to 30 bucks. And the valve is located near the gas tank.

Thanks. you can rate this solution and show your appreciation.

Codes PO 442, 449 and 455


Check all vacuum lines from the gas tank to the evaporative charcoal cannister by the gas tank and to the purge valve located at the engine. Check the electrical connector at the vent solenoid which should be located on the charcoal cannister and purge valve solenoid by the intake manifold.

Where is the purge solenoid location on a 1996 Chevrolet silverado 1500 ???? trucks runs bad and I was told it was that or some other vacuum leak also I have code p0300 and p1441 if anyone can help...


A P0300 DTC is a misfire code. The P1441 is a no flow during purge code which has to do with the purge solenoid. With the misfire code present I would say you have a vacuum leak on one of the hoses. The purge solenoid is located in the passenger side, rear of the intake manifold.
