Question about 2005 Nissan Altima
Basically that is a communication code between one or more computers
you need a dealer scan tool or something similar like the $8000 snap-on scanner to verify which computers are suspect and a DVOM to measure voltage on the communication circuits between the suspect computers
long story short.... this is a job for a select few technicians.... your best bet, depending on where you live.... is the dealer

A p0420 code indicates a Catalytic System efficiency failure, Bank 1.
Basically, the computer is seeing reduced efficiency of the catalytic converter or one of it's components (such as an 02 sensor)
There may be a few root causes, such as a faulty oxygen sensor, faulty coolant temperature sensor, faulty converter, Large exhaust leak, or retarded (slow) timing.

hi, C1000- Engine; CAN Communication Circuit.
That and maybe water got into a connector. Maybe the AWD connector. Be sure to read the LAN System section in the SM. and the TF transfer section. Sounds like the CAN line going to the AWD clutch got shorted or opened. Problem is the full diagnostics need the Consult 4. I think may be it can help you.
