Is 2005 Tucson 2.7 an electronic throttle or a cable throttle?

We know that the flow of combustible mixture can be controlled by controlling the throttle opening, so as to change the speed and power of the engine to meet the needs of automobile driving. The traditional engine throttle control mechanism works through a cable (soft steel wire) or a pull rod. One end of the cable is connected with the accelerator pedal, and the other end is connected with the accelerator linkage plate. However, the application of this traditional throttle valve is limited and lacks accuracy. With the rapid development of automotive electronic technology, Electronic Throttle (EGAS) came into being.

Compared with the traditional throttle, the obvious point of electronic throttle is that it can replace cable or pull rod with wire harness, install a micro motor on the throttle side, and use the motor to drive the throttle opening. That is, the so-called "wire drive" uses wire to replace the original mechanical transmission mechanism. But this is only the surface of electronic throttle, and its essence and function are far from enough to replace analysis with connection.

The electronic accelerator control system is mainly composed of accelerator pedal, pedal displacement sensor, ECU (electronic control unit), data bus, servo motor and accelerator actuator. The displacement sensor is installed in the accelerator pedal to monitor the position of the accelerator pedal at any time. When the height and position of the accelerator pedal are monitored, the information will be sent to ECU immediately, and ECU will calculate and process the information and data information sent by other systems to calculate a control signal. It is sent to the servo motor relay through the line, and the servo motor drives the throttle actuator. The data bus is responsible for the communication between the system ECU and other ECU. Because the electronic throttle system adjusts the throttle through ECU, it can be equipped with various functions to improve driving safety and comfort, among which ASR (traction control system) and speed control system (cruise control system) are the most common.
