Re: Check engine light codes p0441 and p0446

Check the Codes here,

http://autorepair.about.com/cs/troubleshooting/l/bl_obd_main.htm


P0441 Evaporative Emission Control System Incorrect Purge Flow



P0446 Evaporative Emission Control System Vent Control Circuit
Malfunction



Why in Hell would anybody replace an O2 Sensor to clear either of these
codes? The trouble is most commonly related to a leak in the gas cap, or if
the car is older, a leak in one of the hoses that serve to vent the system.
