P1110 NISSAN: INTAKE VALVE TIMING CONTROL BANK 1
The valve timing system provides continuous hydraulic control of the cam phases. It takes into account the fixed operating angle of the intake valve. The ECM (Engine Control Module) provides signals of the camshaft position, crankshaft position, engine temperature, and speed. Then, it gives the on/off pulse service signals to the intake valve timing control solenoid required by the driving conditions. In this way, the engine torque is increased at different engine speeds by controlling the timing of the intake valve opening and closing.
The intake valve timing control solenoid adjusts the amount of oil and the direction of the synchronization unit. It can decide whether to send or stop the oil flow. The pulse width determines the valve angle. If it is longer, the width is advanced. On the other hand, if it is shorter, the angle is delayed. When the on and off pulse widths are equal, the solenoid stops the flow of oil pressure. Thus, it seeks to set the valve angle to the control position.
The diagnostic code P1110 OBDII is a manufacturer-specific code. In the case of Nissan, it indicates that the ECM detects a wrong operation in the intake valve timing solenoid for bank 1.
