Cougar Posted July 28, 2009 Share Posted July 28, 2009 The error code P0446 is a code showing an electrical problem with the circuit to that valve. You stated you saw 14 volts getting to the coil of the solenoid and if I understand correctly you saw 26 ohms for the coil resistance which should be correct I think. If these things are correct then there must be a bad connection to the coil somehow. Quote Link to comment Share on other sites More sharing options...
DCor Posted October 11, 2009 Share Posted October 11, 2009 So I think I FINALLY have the error code licked, go for a run & boom, on comes the light again Check the code and now it's P0443! Getting frustrated with this EVap stuff! Quote Link to comment Share on other sites More sharing options...
DCor Posted January 28, 2013 Share Posted January 28, 2013 I know it's been quite awhile but I wanted to finish off my P0446 code experience. After checking & cleaning, or replacing, many of the parts and areas advised to, it ended up being a serverly corroded wire connection to the O2 sensor!! Cleaned it all up and it has been running without the light coming on for months. Quote Link to comment Share on other sites More sharing options...
