(powertrain control module, also called an ECM). That consists of a few different components but the P0021 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. A P0021 engine code is basically the same as a P0011 code, except this is for Bank 2, not Bank 1.
Symptoms Possible sumptoms of OBD code P0021
Most likely a P0021 DTC 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 Possible causes of OBD code P0021
A P0021 DTC trouble code may be caused by one or more of the following:
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.

The 1.8 and the 2.8 motors are common to throw those codes when the timing chain adjuster fails. the guides (shoes) start to break apart, take the valve cover off and check the tensioner

Hi there:P0021 - "A" Camshaft Position - Timing Over-Advanced or System Performance (Bank 2)

The switch is located immediately below the hole in the trunk side trim.

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.

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)

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.

Thank you for using FixYa, have a nice day.

P0011 "A" Camshaft Position - Timing Over-Advanced or System Performance (Bank 1)
P0021 "A" Camshaft Position - Timing Over-Advanced or System Performance (Bank 2)

both codes indicate timing overadvanced.

You got two codes for Timing Over
Advanced

P0011-Bank 1
P0021-Bank 2

I'am assuming you know that

Cams moved, I would think,
when you did tensioners !!

Or , you have to reset the sensors,
of which I don't know your system
