DTC P1212 - Mass Air Flow Circuit Intermittent Low
DTC P0011 - "A" Camshaft Position - Timing Over-Advanced or System Performance (Bank 1)

A P0011 DTC 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.

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.

The P0011 means "A" Camshaft Position-Timing Over-Advanced or System Performance (Bank 1)
The P1212 means Injector Control Pressure Not Detected During Crank

It is definatly a timeing problem but 1st check you pluged all wireing back in especially cam sensor & VVT solinoid if fitted. You may just need to reset the code & see if prob remains. I had a honda engine light come on after haveing VVT solinoid out & just had to reset comp & it was fine. If all looks good there you will need to recheck the cam timeing you could be a tooth out. Look at this link. http://www.permoveo.ltd.uk/tabid/122/OBD-Error-Code/P0011/Diagnostics/Nissan/Default.aspx

TROUBLESHOOTING P0011
The pcm has determined that the voltage signal from camshaft "A" position sensor in bank 1 indicates inadequate perforemce or a timing over advanced condition. (Bank 1 identifies the location of cylinder #1, while bank 2 identifies the cylinders on the opposite bank)

hopefully this helps a little

P0011 Intake Valve Timing Control

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

What does that mean?
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 P0011 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:
A P0011 DTC 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.

Hope helps (remember rated this).

P0011 - Intake camshaft position timing ( over advance bank 1 )
O0420 - catalyst system efficiency below threshold bank 1. Hope this was helpful.

P0011 (Bank 1)
Intake valve timing control performance, There is a gap between angle of target and
phase-control angle degree.
Causes:
- Harness or connectors (Intake valve timing control solenoid valve circuit is open or shorted.)
- Intake valve timing control solenoid valve
- Crankshaft position sensor (POS)
- Camshaft position sensor (PHASE)
- Accumulation of debris to the signal pick-up portion of the camshaft
