VEHICLE SPEED SENSOR CHECK
1. Remove the vehicle speed sensor and connect a 3 - 10 kilo ohms 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: 0 or Battery Voltage (1turn = 4pulses)
