DTC P0120 THROTTLE POSITION SENSOR; Component Description; CONSULT-II Reference Value
EF & EC-7090spec tableSource table merges 'Condition' rowspan across throttle states; flattened so each row carries its own condition. (a) and (b) are graph-axis labels referenced in the table — preserved verbatim.

Component Description
The throttle position sensor responds to the accelerator pedal movement. This sensor is a kind of potentiometer which transforms the throttle position into output voltage, and emits the voltage signal to the ECM. In addition, the sensor detects the opening and closing speed of the throttle valve and feeds the voltage signal to the ECM. Idle position of the throttle valve is determined by the ECM receiving the signal from the throttle position sensor. This sensor controls engine operation such as fuel cut. On the other hand, the "Wide open and closed throttle position switch", which is built into the throttle position sensor unit, is not used for engine control.
