What is code P0447?
A P0447 code means that the powertrain control module (PCM) has detected a reading from an EVAP sensor that is not in compliance with manufacturer’s specs, resulting in a stored trouble code and illuminated malfunction indicator lamp (MIL).
What is the evaporative emissions vent control valve?
The evaporative emission control (EVAP) system prevents fuel vapors from escaping into the atmosphere. The vent control valve is controlled by the engine control module (ECM) and allows air to flow into the charcoal canister to purge the gas vapors into the engine air intake to be burned.
What does the EVAP canister do?
EVAP Canister: The EVAP canister houses 1-2 pounds of activated charcoal that acts like a sponge by absorbing and storing fuel vapors until the purge valve opens and allows the vacuum of the engine intake to siphon the fuel vapors from the charcoal into the engine intake manifold.
What parts make up the EVAP system?
A typical system consists of the fuel tank, an EVAP vapor storage canister full of charcoal, valves, hoses and a sealed fuel tank gas cap. The EVAP system is designed to stop fuel system fumes from leaking directly into the atmosphere.
How do you fix an evaporative emissions problem?
Tightening your gas cap (and clearing the OBD II codes) can solve the problem for many drivers. However, when the check engine light does not go off—AKA the code clears and comes back—that might indicate a more severe problem in the evaporative emission system.
Can I drive with a P0449 code?
Code P0449 does not pose any serious danger to the driver or the vehicle and there are no drivability issues that may occur. However as the case with all Check Engine Light codes, it should be fixed as soon as possible to prevent any further damage to your vehicle.
