It is always a bit stressful when your vehicle isn’t performing right, and especially if this lack of performance is coupled with the auto code 1446 emissions control systems in cars being indicated through the use of a scanner. When the “check engine” light comes on in any car equipped with an on-board diagnostic system or OBD-ll, the owner or driver can take the vehicle to any repair shop, auto parts store or dealership and have the results scanned. This process then generates all the faults or malfunctions in the emissions system into a series of code. The auto code 1446 emissions control systems, cars and trucks, means that there is a problem with the vent control valve. This fault can occur in more than one set of the auto code 1446 emissions control systems. Cars or trucks can be reset and driven again, then checked to see if the fault occurs. Sometimes something as simple as a loose gas cap or a tear in the seal around the gas cap can lead to the fault reading auto code 1446 emissions control systems. Cars are easy to fix if this is the problem, simply reset the system and correctly tighten the gas cap or replace the damaged gas cap to correct the problem and prevent the faulty reading from occurring.
The vent control valve, or more specifically the EVAP canister vent control valve is located at the actual canister itself, which works to trap the vapors produced when gas is heated. The valve typically is in the open position to allow the vapors to vent from the tank and carborator into the charcoal of the canister, then be drawn back into the engine and burned with the fuel air mixture the next time the vehicle is started. When there is a problem that results in an auto code 1446 emissions control systems, car’s warning or fault reading, it is often necessary to replace the vent control valve to stop the fault from occurring. Not a costly repair the valve replacement typically corrects the reading and make sures that the vehicle will continue to operate at peak efficiency.
The only time that the solenoid valve (vent control valve) is closed is when the diagnostic test is running. In this case the valve closes to allow the system to pressurize to test for leaks. If the valve doesn’t seal or close for some reason during this process the diagnostic test cannot be completed. In some cases the valve may also stick closed, again impeding the operation of the evaporative emissions control system and resulting in a fault reading of auto code 1446, emissions control systems. Cars that have this fault or problem may have some lack of power or acceleration and may also have rougher idling under certain conditions.
