Nissan P0012 is a diagnostic trouble code (DTC) that indicates an issue with the camshaft position actuator circuit in Bank 1, which refers to the side of the engine that contains cylinder 1.
The camshaft position actuator is responsible for adjusting the camshaft position in relation to the crankshaft position to control valve timing. When the Engine Control Module (ECM) detects that the camshaft position is not within the expected range, it sets the P0012 code and triggers the Check Engine Light to turn on.
There are several potential causes for the P0012 code, including a faulty camshaft position sensor, a malfunctioning camshaft position actuator, or a problem with the timing chain or belt. Other possible causes include issues with the oil pressure or oil control valve, or a problem with the ECM itself.
To diagnose and repair the cause of the P0012 code, it is best to take your vehicle to a qualified mechanic who can use specialized diagnostic equipment to identify the source of the problem. They may need to inspect the camshaft position sensor, actuator, and other related components to determine the cause of the issue and make the necessary repairs.
