SOURCE: solutions in fixing engine code 0446 on a 2002

check for a blockage in the line or piched if thats ok
then the is a fuel pressure sensor that can cause a p0446
you have to take the fuel tank out and the sensor is on the fuel pump module
you may want to take it and get the EVAP SYSTEM SMOKE TESTED
hope this helps

Hi, a P0446 means Evaporative Emission Control System Vent Control Circuit Malfunction

That code is for your knock sensor which is located under your intake manifold. There are two under the intake. I would recommend replacing both, they are 40 dollars a piece usually plus the labor to remove the intake.

You will need a OBD2 code reader, that will give you a "trouble code" then that will tell you what direction to look in, for the problem.
