SOURCE: 2003 toyota highlander OBD code's po442/po446/po441

if the air filter was recently inspected or changed, look for the vacuum hose to be disconnected from the valve located on the air filter cover. another source may be the gas cap either loose or with the tether strap caught under it preventing a proper seal

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

My service engine light is on and the code is PO446 with the emission system (Advance Auto confirmed the code). What do I need to replace to repair this problem?


What engine? it could be a bad gas cap, thats about all you can check, a repair shop will need to go deeper to diagnose.

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.

OBDII CODE PO446. WHAT NEEDS TO BE REPLACED


The vapor pressure sensor, VSV for canister closed valve (CCV), VSV for pressure switching valve are used
to detect abnormalities in the evaporative emission control system.
The ECM decides whether there is an abnormality in the evaporative emission control system by the vapor
pressure sensor signal.
DTCs P0441 and P0446 are recorded by the ECM when evaporative emissions leak from the components
when there is a malfunction anywhere in the VSV for EVAP, the VSV
for pressure switching valve, or in the vapor pressure sensor itself.

checked basic , gas cap.

More than likely you need to take to a garage , rec. dealership
will have to perform a smoke check to see if there is a leak somewhere or wether there is a malfunction with a vac. solinoid valve(vsv)
