Nissan 2005 P0011, P0021, and P0340 Fault Codes: Causes and Solutions

Model: nissan 2005 Fault Code: P0011 Posted: 2017-01-08 17:29

I own a 2005 Nissan vehicle and am currently experiencing engine fault codes P0011, P0021, and P0340. These codes indicate potential issues with sensors or engine timing components. Based on the symptoms, it appears there may be a failure of the Cam Position (CMP) sensor, a stretched timing chain, low oil pressure, or malfunctioning variable valve timing actuators—though simultaneous actuator failures are unlikely. I have already checked the sensors and confirmed the fault codes. My question is: what is the most likely root cause? Should I start by replacing the CMP sensor? If so, how many such sensors exist in this model? After replacement, should I clear the DTCs and attempt to restart the engine to see if the codes reappear? Additionally, could you confirm which engine variant (e.g., 3.0L V6) I am dealing with? Any guidance on diagnostic steps would be greatly appreciated.

I have a 2003 Infiniti I35 with engine code P0021. I'm looking for advice on how to diagnose and fix this issue—any recommendations for troubleshooting steps or potential causes?

Is there only one such sensor in your vehicle? After replacing it, clear the DTCs and attempt to start the engine. Observe if any codes reappear. What specific engine type (e.g., 3.0L V6) do you have?\nMholmes83 wrote:\nI have a 2003 Infiniti I35 with code P0021. Looking for help diagnosing this issue.\nPossibility: a faulty actuator in Bank 2. Can you swap the Bank 2 actuator with Bank 1? After swapping, clear DTCs and see if the P0011 code appears on Bank 1—this would confirm whether the actuator is at fault.
