What is the reason for the low signal of throttle driving angle sensor?

There are three main reasons for the low signal of the throttle drive angle sensor. The first point is whether the signal of the accelerator drive angle sensor reaches the position of the pedal. If there was no signal in the past, it was a line problem. The second point is that the fault of crankshaft position sensor leads to excessive oil adjustment and inaccurate throttle opening adjustment. The third point is that the high voltage pulse generated by the discharge leakage of the high voltage line signal affects the normal transmission of the signal line.
