Question

What does P0001 mean on a 2002 Nissan Sentra GXE 1.8L, and how do I fix it?

Answer 1

Nissan Sentra does not use P0001 code, try to use a different OBD-II reader.

Answer 2

The P0001 code is for the Fuel Volume Regulator Control Circuit/Open, but Nissan doesn't use the code. Please double-check the code number or check the codes with a different scanner.
