P1136 NISSAN, INFINITI: INTAKE VALVE TIMING CONTROL SOLENOID VALVE CIRCUIT BANK 2
Some engines are equipped with an intake valve timing controller, which continuously adjusts the valve phasing according to driving conditions. This whole process is to improve low-mid range engine torque and high-speed range engine output, which produces low emissions and increases fuel consumption.
The intake valve timing control system has constant cam phasing control under constant valve operating angle conditions and adjusts the operating oil pressure to the controller via a control solenoid. The intake valve timing control solenoid is activated by ON/OFF pulse service signals from the ECM (Engine Control Module). This solenoid changes the amount of oil and the direction of oil flow to be sent through the timing control unit or whether oil flow will be stopped.
When the voltage sent from the control solenoid to the ECM is not within the expected range, the fault code P1136 OBDII will be set.
The P1136 OBD2 diagnostic code is set by one or more of the following factors:
The steps to follow to correct the DTC P1136 OBDII code are as follows:
