2001 Sentra CA 1.8L Fuel Volume Regulator Issue with P0001 OBD2 Code
My 2001 Sentra CA 1.8L is displaying a P0001 diagnostic trouble code on the OBD2 scanner. I've been told that this code does not exist for my vehicle model, but it's showing up consistently. Can anyone confirm whether P0001 is valid for the 2001 Sentra CA and what it might indicate? The code refers to a fuel volume regulator control circuit or open circuit — could this be related to the fuel system or sensor wiring?
P0001 corresponds to 'Fuel Volume Regulator Control Circuit/Open' in OBD2 standards. This code typically indicates an issue with the control circuit of the fuel volume regulator, which may involve a faulty sensor, wiring harness, or electrical connection in the fuel system.
