P1225, P1234 TP SENSOR
Description
Electric throttle control actuator consists of throttle control motor, throttle position (TP) sensor, etc. The throttle position sensor responds to the
throttle valve movement.
The throttle position sensor has two sensors. These sensors are a kind of potentiometers which transform the throttle valve position into output
voltage, and emit the voltage signal to the ECM. In addition, these sensors detect the opening and closing speed of the throttle valve and feed 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.
