The p0442 is a moderate leak in the EVAP control system and p0455 is a large leak in the EVAP control system. First thing is to ensure that your filler cap is on tight and that the seal is effective. Next is to check the tubing of the EVAP system for any holes or disconnections. The P1404 is the valve in your EGR (exhaust gas recirculation) is staying closed. It could also be that the EGR piping is clogged up with soot (baked carbon deposits). Similarly the p0404 is an EGR related error code. Your vehicle is quite new and it would be unusual for the EGR to pack up or require cleaning out so early in its life. I would make sure that the connector pins in the connection socket to the EGR are clean and bright and that there no breaks in the wiring back to the power control module. If no joy then remove the EGR and examine the freedom of movement of the valve. If gummed up spray liberally with carburettor cleaner spray and leave to stand for at least ten minutes before wiping away the crud. Repeat until the valve looks like new and reinstall. After four or five restarts without fault the error code should clear.

P0442 - Evaporative Emissions System Leak Detected (Small Leak)
P0455 - Evaporative Emissions System Leak Detected (Gross Leak)
This diagnosis detects leaks in the EVAP purge line using engine intake manifold vacuum. If pressure does not increase, the ECM will check for leaks in the line between the fuel tank and EVAP canister purge volume control solenoid valve under the following vacuum test condition. The vacuum cut valve bypass valve is opened to clear the line between the fuel tank and the EVAP canister purge volume control solenoid valve. The EVAP canister vent control valve will then be closed to shut the EVAP purge line off. The EVAP canister purge volume control solenoid valve is opened to depressurize the EVAP purge line using intake manifold vacuum. After this depressurization is implemented, the EVAP canister purge volume control solenoid valve will be closed.
- Missing Fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- Incorrect fuel tank vacuum relief valve
- Leak is in line between intake manifold
- Re-tighten or replace fuel tank filler cap
- Replace damaged or leaking EVAP canister
- Replace damaged or leaking lines.

This indicates that a part of the EVAP control system is no longer functioning correctly. The EVAP system consists of many parts, including (but not limited to) the gas cap, fuel lines, carbon canister, purge valve, and other hoses. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.
I suggest replacing the gas cap with preferably one from the Nissan dealer, or OEM equivalent, then clear these codes by disconnecting the negative battery cable for about a minute then drive it normally; if the codes come back, this may take a couple of days, you most likely have to have the system tested for leaks.
Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.
Thank you for using FixYa, have a nice day.
