Cougar Posted May 24, 2009 Share Posted May 24, 2009 The code states there is a problem with the circuit to the evaporative filter. Most likely a bad connection to it. There is a different code for a shorting problem. Quote Link to comment Share on other sites More sharing options...
OB99W Posted May 25, 2009 Share Posted May 25, 2009 The full definition for P0446 is ''Evaporative Emission Control System Vent Control Low Input''. As Cougar mentioned, the cause is often a bad (corroded) connection, although the vent control solenoid valve's coil could be bad, etc. The topic comes up here periodically. I'd suggest you scroll down the page and look at the ''Similar Threads'' there, and/or use the forum search function, searching for ''P0446''.
