P1122 2002 NISSAN ALTIMA SEDAN MeaningElectric Throttle Control Actuator consists of throttle control motor, Throttle Position Sensor (TPS), etc. The throttle control motor is operated by the Engine Control Module (ECM) and it opens and closes the throttle valve.
The throttle position sensor detects the throttle valve position, and the opening and closing speed of the throttle valve and feeds the voltage signals to the ECM. The ECM judges the current opening angle of the throttle valve from these signals and the ECM controls the throttle control motor to make the throttle valve opening angle properly in response to driving condition.
