Working principle of six-wire accelerator pedal, how to measure six-wire accelerator pedal?

The accelerator pedal is mainly used to control the opening of the engine accelerator, thus controlling the power output of the engine. With the continuous development of automotive electronic technology, the application of electronic throttle is more and more extensive. Nowadays, cars are basically electronic accelerator pedals. The accelerator pedal has five lines and six lines, but most of them are six lines. There are two sensors in the six-wire accelerator pedal, and the six wires are two power wires, two signal wires and two ground wires respectively.

Working principle of six-wire accelerator pedal

Electrical principle of electronic accelerator pedal According to the type of pedal position sensor, electronic accelerator pedal can be divided into contact type and non-contact type. At present, the most widely used is the non-contact programmable electronic accelerator pedal based on Hall effect, and its electronic accelerator pedal angular displacement sensor is installed inside the accelerator pedal to monitor the position of the accelerator pedal.

When it detects that the height position of the accelerator pedal changes, it will convert this information into voltage and send it to ECU. ECU will use these information and data information of other systems to calculate the optimal throttle opening, which will be sent to the servo electronic throttle motor relay through the line, and the servo motor will drive the throttle to perform related actions.

How to measure accelerator pedal line 6?

1. Read the data stream through the decoder to see if there is any fault code;

2. Check the voltage of line 6 of the sensor with a multimeter voltage range to see if it will change with the accelerator pedal.
