I checked the codes and one comes up its po446. i dont under stand what it mean so i cant fix it to get the light to go out.

DTC stands for Diagnostic Trouble Code. My question is why did you have the vehicle checked out in the first place? Is the check engine light on? What was the code number and did it start with P0 or P1. If you don't remember then have the code(s) cleared and operate the vehicle until the code(s) reappear. The code or codes can help you to determine where to start looking.

My check engine light come up w/ all these code P0305,P0440,P0441,P0446 what's wrong Thanks

po305 is related to missfire on #5 cylinder
po440 is related to fuel tank pressure
pO441 is for evaporator purge flow malfunction
po446 relates to vent control valve electrical circuit malfunction

missfire is seperate from the other codes
as for the other three codes replace the vent control valve solenoid located near the charcoal canister the oth3er codes can relate to a faulty solenoid

after replacing light will only go out if you clear through a scan tool or three drive cycles of over 10 min each

Check engine come on code po446 hoow u that?

The "check engine" warning light advises that the vehicle is in "fail safe" mode. That means only some of the car's capabilities are operational, just enough to get you to the nearest service point. You probably should not drive it any further than that. Have your service man download and analize the fault codes from the ECM which will indicate what the problem code is.

P0446 Evaporative Emission System Vent Control Circuit.
The following are descriptions of all Evaporative possible codes:

P0441 Evaporative Emission System Incorrect Purge Flow
P0442 Evaporative Emission System Leak Detected (small leak)
P0443 Evaporative Emission System Purge Control Valve Circuit
P0444 Evaporative Emission System Purge Control Valve Circuit Open
P0445 Evaporative Emission System Purge Control Valve Circuit Shorted
P0446 Evaporative Emission System Vent Control Circuit
P0447 Evaporative Emission System Vent Control Circuit Open
P0448 Evaporative Emission System Vent Control Circuit Shorted
P0449 Evaporative Emission System Vent Valve/Solenoid Circuit
P0450 Evaporative Emission System Pressure Sensor/Switch
P0451 Evaporative Emission System Pressure Sensor/Switch Range/Performance
P0452 Evaporative Emission System Pressure Sensor/Switch Low
P0453 Evaporative Emission System Pressure Sensor/Switch High
P0454 Evaporative Emission System Pressure Sensor/Switch Intermittent
P0455 Evaporative Emission System Leak Detected (large leak)
P0456 Evaporative Emission System Leak Detected (very small leak)
P0457 Evaporative Emission System Leak Detected (fuel cap loose/off)
P0458 Evaporative Emission System Purge Control Valve Circuit Low
P0459 Evaporative Emission System Purge Control Valve Circuit High
---
At least the cap isn't loose for the gas tank.

I would clear the code with an OBD-II Scanner 'erase code' button, and see how long it takes for it to come back.
