Hi there Camilo:
DTC P0011 - "A" Camshaft Position - Timing Over-Advanced or System Performance (Bank 1)
A code P0011 refers to the VVT (variable valve timing) or VCT (variable camshaft timing) components and the car's PCM (powertrain control module, also called an ECM). That consists of a few different components but the P0011 DTC specifically refers to the camshaft (cam) timing. In this case, if the cam timing is above a set limit (over-advanced), the engine light will be illluminated and the code will be set. The "A" camshaft is either the intake, left, or front camshaft.
Potential Symptoms
Most likely a DTC P0011 will result in one of the following: hard starting, poor idle, and/or stalling. There are potentially other symptoms as well. Of course, when trouble codes are set, the MIL (malfunction indicator lamp, a.k.a. the check engine light) illuminates.
Causes
A DTC P0011 trouble code may be caused by one or more of the following:
- Incorrect camshaft timing
- Wiring problems (harness/wiring) in intake timing control valve control solenoid system
- Continuous oil flow to VCT piston chamber
- Failed timing valve control solenoid (stuck open)
Possible Solutions:
This DTC code is a result of a mechanical fault of the VCT unit or related components, so there is no need for electrical diagnosis. Refer to vehicle specific repair manual to perform component tests for the VCT unit. Notes: Dealer techs have advanced tools and the ability to follow detailed troubleshooting steps, including the ability to test components using a scan tool.

DTC P0462 - Fuel Level Sensor Circuit Low
This could happen happen you ran your fuel tank too low I would first fill up the tank and go to your local parts store and have them reset the code to see if it stays off .If the light comes back on the most likely reason is because the fuel level sensor needs to be replaced but other possible causes are wiring problems, fuel pump module, or cluster. You will need to barrow a special tool which is the lock wring wrench from your local parts store to remoe the fuel pump. Here are instructions from Nissan TSB (Technical Service Bulletin) to solve it; let me know if you have questions.
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.

Timing is out of sequence. Have your timing checked soon to be safe. If your timing goes too far out the piston could slap the valve and wreck your motor. is there any other codes present? Usually if its a bad sensor you will havea sensor code too...

I think your sensors are pattern parts and the readings /resistances are not the same as the original parts ,try some bosch units is my first suggestion ,
