My '08 just started throwing this code...anyone know specifically what it relates to? All I could find was something to do with the 4WD switch.

If the code is alone, it could mean there's a short somewhere in the wiring of your 4WD command chain. I'd start with the switch.

If the code is accompanied by other related codes, there could be a transmission problem.

There is also a code p0443, which looks like Nissan has a TSB for.

That's your evap system, which is different. I meant transmission codes.
