P1122 INFINITI Meaning
The electronic throttle control actuator consists of a 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/closing speed of the throttle valve, and sends voltage signals to the ECM. The ECM determines the current throttle valve opening angle from these signals and controls the throttle control motor to properly adjust the throttle valve opening angle according to driving conditions.
