Why does the throttle position sensor motor have two ground wires?

Better electrical grounding to ensure system safety.

1, Better electrical grounding: The first grounding wire is the metal shell or fuselage connecting the sensor motor, thus forming a good electrical grounding between the motor and the earth.

2. Ensure the safety of the system: The second grounding wire is used to connect the internal circuit of the sensor motor to ensure the equipotential connection between all parts in the circuit, reduce the grounding impedance in the current loop and improve the stability and accuracy of the circuit.
