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!

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.

Purge valve location 2001 chevy cavalier 2.2


The EVAP Purge valve, on your vehicle, is located in the engine compartment. Yours is on the top of the front-right side (passenger side) of the engine. Just in case you need to know where the EVAP Vent valve/solenoid is located, it is underneath. It is tucked away at the rear part of the car, between the fuel-tank and the right-rear fender well. I hope that helps, good luck.

2003 chevy cavalier p440 code


This indicates that a part of the EVAP control system is no longer fuctioning correctly. The EVAP system consists of alot of parts, including 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 vehicles 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 engin

heres some things you can try
Remove and reinstall

the gas cap, clear the code, and drive for a day and see if the codes come back.
Inspect the EVAP system for cuts/holes in tubes/hoses
Inspect for damaged or disconnected hoses around the Evap purge solenoid
Check and/or replace the sensor
Check and/or replace the purge valve
Have a professional use a smoke machine to detect leaks
