Vehicle Speed Sensor

Vehicle speed sensor is a P/M generator and switching transistor located in speedometer head. ECM supplies and monitors a voltage signal to speed sensor. As P/M generator rotates (vehicle moving), switching transistor in speed sensor grounds and ungrounds reference voltage signal from ECM terminal A10. ECM uses this signal to help determine control of the Idle Speed Control (ISC) solenoid.
