The evaporative control (EVAP) system collects raw fuel escaping from the fuel tank. This information is then communicated to the ECM which regulates the emissions of the vehicle. The P0443 code is set when the ECM detects a malfunction within the purge control valve or a short in the purge valve circuit.

Where is the EVAP vent solenoid located?
In most cars, the EVAP vent valve is located underneath the vehicle, close to or at the charcoal canister near the fuel tank, see the photo.
Is code P0443 bad?
DTC P0443 is not typically classified as being overly serious. Quite the contrary, a vehicle can often be driven with an active P0443 trouble code, without the worry of additional issues. However, in rare instances, P0443 can be accompanied by a rough or erratic idle.
What is the code P0449?
Code P0449 Meaning
Hydrocarbons form smog when they react with air and sunlight. ... When the trouble code P0449 is set, this is an indication of the EVAP system vent valve solenoid malfunctioning which results in more hydrocarbons being expelled into the atmosphere.
Where is the purge valve located?
Vapor Canister Purge Valve Location
The Canister purge control valve is most often located in the engine bay on a hose going from the intake to the canister. It can also be located near the fuel tank.
How much does it cost to replace a vent solenoid?
Replacing a canister purge solenoid is a pretty straightforward type of job that doesn't cost too much. Expect to pay anywhere from $80 to $200 in total. The part will typically cost anywhere from $30 to $120, while the labor costs will be right around $50 to $80.
What happens when EVAP solenoid goes bad?
On top of a rough idle, a vehicle with a failing EVAP canister purge valve will display signs of poor engine performance. The engine may feel like its running “weak” and won't generate sufficient power for acceleration. Accelerating will feel like you're pressing the pedal down and moving slower.
When should purge valve open?
When your engine is off the valve is closed. Once your engine is up and running the computer continuously and moderately opens the purge valve. This action allows fuel vapor to move from the charcoal canister to burn in the engine.
What does P0444 mean?
Diagnostic trouble code (DTC) P0444 stands for “Evaporative Emission System Purge Control Valve Circuit Open.” This code is logged when the PCM detects a problem with the purge valve circuit. On vehicles with an Evaporative Emission Control System (EVAP), fuel vapors from the gas tank are stored in a charcoal canister.
Can you drive with a bad purge valve?
It's certainly possible to drive with a broken purge valve, but we don't recommend it. The longer you drive with a bad valve, the more risk you run of damaging the vehicle's EVAP system and other parts. There's also the possibility of wasting fuel and pumping out more emissions than is necessary.
How much does it cost to replace purge valve?
To have your canister purge valve replaced, you will pay anywhere between $110 and $170. The parts are the expensive component here, as they will run between $75 and $110. The labor, on the other hand, usually only costs about $50, meaning this is a rather quick and straightforward procedure.
Can I bypass EVAP canister?
Now just unplug the pressure sensor and unbolt the Charcoal Canister to pull it all out. Easy peasy! This can easily be done without any modifications in just a few minutes, so everything can easily be put back into place when you need to pass SMOG or Inspection.
