Vehicle Speed Sensor: Testing and Inspection

VEHICLE SPEED SENSOR CHECK




1. Remove the vehicle speed sensor and connect a 3-10 kilo ohm resistor as shown in the illustration.
2. Turn the shaft of the vehicle speed sensor and check that there is voltage between terminals 2 - 3. (1 turn = 4 pulses)
3. If within the standard value, the vehicle speed sensor is OK. If not within the standard value, replace the vehicle speed sensor.

Standard value: Voltage alternates between 0 volt and 5 volts four times per turn.
