The vapor pressure sensor is attached to the charcoal canister via 2 screw and a tube. there is also an electrical plug that goes to the computer.
other possible causes would be
The canister itself- either physical damage or fuel damage(causes by topping off your tank)
the air filter in the evap system
physical damage to the tubing or poor connections ( an evap smoke test will answer those questions)
a wiring problem ( an open or a short)
or the computer itself is bad.
Diagnosing these problems is difficult for the "at home mechanic" to do. this is a tricky spot that may be left to the pro's.
I am not a mechainic for a living but i worked on my truck for a P0450 Nissan code at it was very difficult isolating equipment to diagnose the situation.

What is car code P 1420 for Nissan cube?
The OBD-II trouble code P1420 for a Nissan Cube indicates an issue with the evaporative emission control system, specifically related to the fuel tank pressure sensor or circuit. This code typically suggests that there is a malfunction in the system that monitors fuel vapor levels, which can lead to increased emissions and potential fuel efficiency issues. It is advisable to check the fuel tank pressure sensor and its wiring for any faults or damage. If necessary, further diagnostic testing may be required to pinpoint the exact cause of the problem.
What does Nissan Maxima code P0441 mean?
The Nissan Maxima code P0441 indicates an issue with the Evaporative Emission Control System (EVAP), specifically related to incorrect purge flow. This can occur due to a malfunctioning purge valve, a leak in the EVAP system, or issues with the fuel tank pressure sensor. As a result, the system may not be properly venting or controlling fuel vapors, leading to increased emissions. It’s advisable to have the system inspected and repaired to prevent potential damage and ensure compliance with emissions regulations.
Rpm won't rise when gas peddle is stepped on?
