What happens if you don’t fix purge valve?
By not fixing this, the Check Engine Light will remain on and by allowing it to stay on, you will now not know the difference when something else major might be wrong since the light will already be on. The danger to this is that you may not discover something else wrong until it is too late.
Will a bad purge valve throw a code?
When a canister purge valve is stuck in the closed position, it will prevent the system from burning the evaporated fuel in the engine. This will cause a low purge flow code and can cause premature failure of the charcoal canister in the evaporative emissions system.
Can a car run without a purge valve?
This valve, although it’s a small component, is crucial for your EVAP system to work properly. Without it, your engine is going to have a hard time working and it will run extremely rich . This rich fuel to air mixture can also have an impact in the long run on other components in your car.

- Fuel Smell Odor. ...
- Failing Emissions Test. ...
- Excessive Smoke From Exhaust.
Is EVAP canister necessary?
The charcoal canister (aka: EVAP canister) is an essential part of the Evaporative Emission Control System (often shortened to “EVAP”). This system helps ensure that dangerous fumes from your gas tank aren’t released into the environment and instead puts them to work powering the engine.
Can a bad gas cap cause a P0449 code?
Causes of Code P0449
