1 Answers
The testing method for an automotive electronic throttle pedal: Use a multimeter, and it's necessary to locate the wiring of the electronic throttle pedal. Measuring the electronic throttle pedal is relatively complex, and it's not recommended for car owners to perform this operation themselves, as the electronic throttle pedal has numerous wires. It is advisable to seek professional assistance for measurement. Electronic throttle pedals are equipped with a pedal position sensor, through which the ECU can determine the extent to which the throttle pedal has been depressed. Older vehicles used a cable throttle design, where one end of the steel cable was connected to the throttle pedal and the other end to the throttle body. Modern vehicles employ an electronic throttle design, with the throttle pedal equipped with a position sensor. When the throttle pedal is depressed, the sensor sends a signal to the ECU, which then controls the throttle opening.
