Error Code ... What now?
P0012
Intake camshaft position timing – over-retarded (bank1)
What does this indicate?
I hope it is the sensor and nothing more than that since it could run you a lot of money.
I also hope you are under warranty.
Specific thread from previous members here:

From the web:
Possible Causes
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 this is just something little. Good luck and let us know!
