How to solve the high voltage of accelerator pedal sensor 2

The voltage of accelerator pedal sensor 2 is high, and the reason for this fault code is that the accelerator pedal position sensor is damaged, the accelerator position sensor is faulty, and the plug is virtually connected. Generally, it is caused by the fault of the accelerator pedal itself, which needs further inspection to determine.

Solution Replace the accelerator pedal. Check whether the accelerator pedal sensor 2, 5V voltage, signal and the three wires above the negative electrode are disconnected from the computer. If the wire is not disconnected, the pedal sensor is disconnected internally.

The electronic throttle can analyze and compare all kinds of data collected by sensors through ECU, give instructions to make the throttle actuator act and adjust the throttle to the best position, so as to achieve the theoretical air-fuel ratio state 14.7: 1 under different loads and working conditions, and make the fuel burn fully.

Extended data:

Electronic throttle structure, electronic throttle control system is mainly composed of accelerator pedal, pedal displacement sensor, electronic control unit, data bus, servo motor and throttle actuator.

The displacement sensor is installed on the accelerator pedal to monitor the position of the accelerator pedal at any time. When it is detected that the height position of the accelerator pedal changes, the information will be immediately sent to the electronic control unit, and the ECU will calculate and process the information and data information from other systems to calculate the control signal.

It is sent to the servo motor relay through the circuit. The servo motor drives the throttle actuator, and the data bus is responsible for the communication between the system ECU and other ECU.
