Relationship between pedal position sensor and throttle opening

The pedal position sensor is located on the pedal. In the cab, the throttle position sensor is located above the throttle.

The throttle position sensor is also called throttle opening sensor or throttle switch. Its main function is to detect whether the engine is in idle or load condition, acceleration or deceleration condition. The accelerator pedal position sensor detects how much the accelerator is depressed, and the computer controls the accelerator motor to rotate at a certain angle according to this signal to meet the air intake under various working conditions.
