P1233 INFINITI Meaning

The electronic throttle control actuator consists of a throttle control motor, throttle position sensor, etc. The throttle position (TP) sensor responds to throttle valve movement.
The throttle position sensor has two sensors. These sensors are a type of potentiometer that convert the throttle valve position into an output voltage and send the voltage signal to the Engine Control Module (ECM). Additionally, these sensors detect the opening and closing speed of the throttle valve and transmit voltage signals to the ECM. The ECM determines the current throttle valve opening angle from these signals, and the ECM controls the throttle control motor to properly adjust the throttle valve opening angle in response to driving conditions.
