5.9.4.6 Mileage Sensor (Speed Sensor)
This sensor is used to detect the rotating
speed of the engine output shaft and
provide the signal for ECU to determine
the vehicle speed. It belongs to Hall effect
sensor, that varies its output voltage in
response to a magnetic field.
Pin function:
1. Ground
2. Output voltage signal
3. Power+DC12V

Mileage sensor test
●Ground pin 1and connect pin 3 with +12V
power.
●Fix a gear 2.5mm away from a speed
sensor as the right figure illustrates.
●Turn multimeter to DCV range.
●Slowly turn the gear and measure
the voltage between pin 2 and pin 3 to
determine that if the reading varies from
0V, 12V.
●If the reading doesn't vary,that indicates
the sensor is defective and needs to be
replaced.
