P1233 INFINITI, NISSAN: ELECTRIC THROTTLE CONTROL PERFORMANCE BANK 2
The Electric Throttle Control (ETC) is an electrical system used in automobiles, whose function is to electronically connect the accelerator pedal to the accelerator. This system replaces the mechanical coupling used in many applications.
Generally, an ETC system consists of an Accelerator Pedal Module (equipped with two or more independent sensors), a throttle valve that is opened and closed by an electric motor, often referred to as an electric throttle body, and the ECM (Engine Control Module). The ECM through software can determine the required throttle position, using calculations from the data measured by the sensors. The electric motor, on the other hand, is used to open the throttle valve to the desired angle through a closed-loop control algorithm within the ECM.
When the DTC P1233 OBDII code is set on Nissan and Infiniti vehicles, it is due to the electric throttle control function not working properly.
The reasons for the P1233 OBD2 fault code being stored are:
The steps to follow to correct the P1233 OBDII diagnostic code are:
