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

Evaporative Emission (EVAP) how to find a leak without replacing canister on chevy silverado 1500

SOURCE: 2004 Chevy Cavalier 2.2 eco Automatic 94,000 miles

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.

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.

EVAP System Vent Circuit Malfunction

This diagnosis detects leaks in the Evaporative Emission (EVAP) purge line using of vapor pressure in the fuel tank. The EVAP canister vent control valve is closed to shut the EVAP purge line. The vacuum cut valve bypass valve will then be opened to clear the line between the fuel tank and the EVAP canister purge volume control solenoid valve. The EVAP control system pressure sensor can now monitor the pressure inside the fuel tank. If pressure increases, the Engine Control Module (ECM) will check for leaks in the line between the vacuum cut valve and EVAP canister purge volume control solenoid valve.

Possible causes
- Incorrect fuel tank vacuum relief valve
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- Leak is in line between intake manifold and EVAP canister purge volume control solenoid valve
- Foreign matter caught in EVAP canister vent control valve
- EVAP canister or fuel tank leaks
- EVAP purge line (pipe and rubber tube) leaks
- EVAP purge line rubber tube bent
- Blocked or bent rubber tube to EVAP control system pressure sensor
- Loose or disconnected rubber tube
- EVAP canister vent control valve and the circuit
- O-ring of EVAP canister vent control valve is missing or damaged
- EVAP canister is saturated with water
- EVAP control system pressure sensor
- Absolute pressure sensor

Possible solution
- Loose fuel filler cap
- Leaking fuel filler cap


Hope helps (remember to rate this answer).

Code says evaporator purge solenoid


Which code specifically? Do not assume you need a new solenoid. Our recommendation will depend on the specific code and some troubleshooting results. I usually recommend checking over all the EVAP vacuum lines and the gas cap too whenever there is a purge valve code. Check the vacuum lines at the cannister in the left rear bumper. I will paste info on the purge solenoid below.

Evaporative Emission Purge Solenoid

Description & Operation
The duty cycle EVAP canister purge solenoid (DCP) regulates the rate of vapor flow from the EVAP canister to the intake manifold. The Powertrain Control Module (PCM) operates the solenoid.
During the cold start warm-up period and the hot start time delay, the PCM does not energize the solenoid. When de-energized, no vapors are purged. The PCM de-energizes the solenoid during open loop operation.
The engine enters closed loop operation after it reaches a specified temperature and the time delay ends. During closed loop operation, the PCM cycles (energizes and de-energizes) the solenoid 5 or 10 times per second, depending upon operating conditions. The PCM varies the vapor flow rate by changing solenoid pulse width. Pulse width is the amount of time that the solenoid is energized. The PCM adjusts solenoid pulse width based on engine operating condition.
Removal & Installation
The duty cycle evaporative (EVAP) canister purge solenoid is located in the engine compartment near the brake master cylinder.

  1. Disconnect electrical connector at solenoid.
  2. Disconnect vacuum lines at solenoid.
  3. Lift solenoid slot from mounting bracket for Removal & Installation.

To Install:
  1. Position solenoid slot to mounting bracket.
  2. Connect vacuum lines to solenoid. Be sure vacuum lines are firmly connected and not leaking or damaged. If leaking, a Diagnostic Trouble Code (DTC) may be set with certain emission packages.
  3. Connect electrical connector to solenoid.
