4. Inspection of Vehicle Speed Sensor Circuit
No. 4 Inspection of Vehicle Speed Sensor CircuitDESCRIPTION OF OPERATION
The vehicle speed sensor, mounted in the transmission, delivers pulse signals proportional to the rotational speed of the transmission output gear (vehicle speed) to the control unit. (Four pulse signals generated per rotation of the output gear) Since the vehicle speed sensor is of the electronic type, the power is supplied through the ignition switch (1G1).
The vehicle speed sensor is a reed switch type and is mounted in the speedometer. It sends pulse signals proportional to the rotational speed of the transmission output gear (vehicle speed) to the control unit. (For pulse signals generated per rotation of the output gear)
