How to resolve the P0014 trouble code?

[MacJulia]

P0014 trouble code represents B camshaft position actuator and timing over-advanced or system performance fault. The English definition of P0014 trouble code is b-camshaft-position-timing-over-advanced-or-system-performance(bank1). The solution is to replace the exhaust camshaft position actuator solenoid valve. The following is relevant information: 1. The function and working principle of camshaft: The camshaft controls the opening and closing of valves. In the variable valve timing system, the electronic camshaft adjustment valve (or oil control valve OCV) adjusts the angle of the camshaft by changing the oil pressure to the camshaft adjuster (mechanical) according to the instructions from the engine control module (ECM), to ensure that the valves open and close at the optimal time. 2. Causes of P0014 fault: including B intake/left/front camshaft timing not set correctly, camshaft over-advanced principle mechanically stuck, or the actuator valve stuck in the open position, briefly described as timing too early or system performance.
