Vehicle Speed Sensor: Notes
WARNING: This page is about a different car, the 2004 Subaru Forester. However, it is still accessible from the selected car via links, so may be relevant.
The vehicle speed sensor uses a Hall IC pick-up to generate speed signals (MT models).
This sensor is installed on the transmission case and detects rotating speed of the transmission output gear.
The sensor generates 4 pulses per rotation of the speed sensor driven shaft and send them to the speedometer.
