I did change two camshaft sensors the intake and out.
Engine management computer is programmed to expect a signal from the cam sensor(s) at the right time in relation to the crank sensor. It will flag it as a fault if the pulse(s) are too early or too late - in your case the pulse is too early, hence over-advanced.
It could mean the valve timing is wrong and it would be advisable to check...

its not hard to fix.but you going to have to move some things to get to it. you will need a haynes repair manual.it will show you photos and instructions how to replace it.
SOURCE: P0012 Intake camshaft position timing over
Code P0012 - Variable Camshaft Timing Over Retarded - Bank 1
How does a P0012 code trigger the check engine light? This code will trigger the check engine light under the following condition:
* The comprehensive component monitor, referred to as the CCM, monitors the Variable Camshaft Timing (VCT) position for over-retarded cam timing. If the cam timing exceeds a maximum calibrated limit or is stuck in a retarded position, the check engine light will come on and set this trouble code.
Possible Causes:
Incorrect camshaft timing
VCT solenoid valve stuck open or continuous oil flow to piston chamber
Camshaft advance mechanism binding, or faulty VCT unit
Diagnostic Help:
This check engine light code is caused by a mechanical fault of the VCT unit or related components, so there is no need for electrical diagnosis. Possible symptoms may include rough idle, stall or hard start. Refer to manufacturer specific component tests for the VCT unit. You may also use the "Get Help" link if you need specifications or have any other related questions. Remember to refer to an appropriate manual for specific instructions.
Other details mentioned a P0012 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:
The main thing to check is to verify the operation of the VCT solenoid. You're looking for a sticking or stuck VCt solenoid valve caused by contamination. 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 to rate and comment this).
SOURCE: I have a P0011 "Camshaft Position/Bank 1 code.
OK check the CMP sensor connector for cleanliness, sometimes oil can get in and disrupt the signal transmission to the ECU. Check the wire loom continuity all the way back from the CMP to the ECU. If the error code persists remove the cam sensor, clean its tip of any debris and refit.
Testimonial: "Thanks joe2mercs...you had the problem diagnosed correctly. Cleaned and light has not come back on. U saved me a lot of $."

SOURCE: what are the codes P0011 on a 2005 VW passat?
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.
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.

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.

Hope helps.

Observe the scan tool CMP Desired, Actual, and Angle Variance parameters before a DTC sets. This may help to isolate whether a condition is specific to one camshaft, one bank, or caused by a condition with the primary crankshaft timing.

I'm sorry but when dealing with these problems your best bet is to take your vehicle to a qualified repair shop , I have never see a DIY'ER correct the problem with these , an in the end always end up taking it to the dealer .

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 ,
