The abbreviation of Control translates into electric throttle control system. This is an important controller for controlling engine intake and engine load. When there is a problem, the engine speed and load cannot be controlled. When there is a problem with the electronic throttle control system, the vehicle will enter an emergency state, causing the engine to shake, and in severe cases, it will turn off.

When judging the problem, it is necessary to detect the power supply voltage of the electronic throttle. Generally, the red line is the power supply line, and the power supply voltage detected by multimeter should be 12V. Also, check the grounding wire of the electronic throttle, which is usually black or brown, and the resistance between it and the negative electrode of the battery should be 0.
