What does evaporative emission control system vent valve malfunction mean?
Evaporative Emission Control System Vent Valve/Solenoid Circuit Malfunction What does that mean? This code is a generic powertrain code. It is considered generic because it applies to all makes and models of vehicles (1996-newer), although specific repair steps may vary depending on the model.
Where is the solenoid located in the EVAP system?
The Engine Control Module (ECM) has determined that a malfunction exists in the electrical circuit for the vent valve/solenoid in the evaporative emission control system. The Evaporative Emission System (EVAP) canister vent control valve is located on the EVAP canister and is used to seal the canister vent.
Where is the EVAP canister vent control valve located?
Engine Light ON (or Service Engine Soon Warning Light) The Evaporative Emission System (EVAP) canister vent control valve is located on the EVAP canister and is used to seal the canister vent. This solenoid (the EVAP canister vent control valve) responds to signals from the Engine Control Module (ECM).
What causes an evaporative emission control system light on?
The Engine Control Module (ECM) has determined that a malfunction exists in the electrical circuit for the vent valve/solenoid in the evaporative emission control system. Engine Light ON (or Service Engine Soon Warning Light)

What is the code for the EVAP vent?
The evap vent valve in most makes and models depends on a supply of a 12V battery voltage with key on. The ECM driver closes this valve when grounded and will set code P0446 if there is an open or short to ground or battery voltage or it is not possible to form a vacuum seal.
What causes an EVAP system code p0446?
Here are the most common causes of an EVAP System Malfunction or code P0446: 1 Malfunctioning vent control valve 2 Clogged vent valve 3 Control circuit issues (e.g., loose or damaged wiring) 4 Powertrain control module hardware or software issues (rather uncommon)
What happens if you puncture the EVAP vent valve?
Punctured or torn hoses of the Evaporative System Faulty fuel tank sending unit gasket or seal The EVAP designed to perform two things: capture, store and expel raw fuel vapor that leaks from the Fuel Storage system and, run self-tests to determine the operation and vapor holding feature of the system.
What is the trouble code on my GMC Sierra?
P0446 GMC Sierra. One of the most common trouble codes with the GMC Sierra is the P0446 code. This trouble code references a number that is given to you when you plug your Sierra into a OBDII scanner. P0446 Indicates that there is a fault in the evaporative emission control system. It often appears with other codes, such as P0420, P0441, or P0440.

What causes the p0446 trouble code on a GMC Sierra?
When the EVAP control system vent control circuit no longer responds to the ECU, it will throw the P0446 OBDII Code. There are many things that can cause the P0446 trouble code to trigger in your GMC Sierra.
