SOURCE: O2 sensor and EVAP issues
P0446 is Aux Emission Control
P0132 Fuel Air Metering
The Evap Canister is located in the fender well, if I am not mistaken and the B1S2 is the O2 sensor is the second O2 sensor on the left side of the engine if your looking at it from the front of the motor.

A qualified repair shop wil need to check these codes and recommend repairs. a scanner and a manual will be needed for diagnosis.

SOURCE: I have a code P1447
My experience with my own 97 Pathfinder was that the EVAP canister internally ruptured, spreading charcoal pellets throughout connected portions of the vacuum system.
The tech replaced the EVAP canister and blew lines out with compressed air, but the P1447 code came back.
A few weeks later I had the tech check why the P1447 code came back, and he determined that the EVAP Canister Purge Volume Control Solenoid Valve had failed, as it did not pass certain resistance measurement tests. He replaced the valve, $288 + labor, blew a few remaining carbon bits out, and the problem seems to be fixed.
I kind of choked at the $288 price though, and took the part home. Two screws to pop it open. Turns out it was filled (surprise) with pulverized charcoal dust and would not operate.
The valve is a little rotating magnet that turns and screws a lipstick-style plunger up and down. I tapped out all the carbon and then started turning the bearings, which were crunchy sounding. However, the carbon eventually gave way to the bearings and they're spinning just fine now. I haven't tested the part, but from the simplicity of it, I have no doubt it would get me down the road many more miles.
