Check Vehicle Speed Sensor

VEHICLE SPEED SENSOR

Step Check Yes No
1 CHECK VEHICLE SPEED SENSOR. 
  1. Lift-up the vehicle and support it with safety stands.
  2. Remove the combination meter with harness connector.
  3. Drive the vehicle at a speed greater than 20 km/h(12 MPH).
    WARNING: Be careful not to get caught in the running wheels.
  4. Measure voltage between combination meter connector and chassis ground.

Connector & terminal 
(i10) No. 13 (+) - Chassis ground (-): 		 Is the measured value less than 1 V or more than 5 V? Check speedometer. < Ref. to , REMOVAL , Speedometer. > Go to step 2. 
2 CHECK VEHICLE SPEED SENSOR POWER SUPPLY. 
  1. Turn ignition switch to OFF.
  2. Disconnect vehicle speed sensor harness connector.
  3. Turn ignition switch to ON.
  4. Measure voltage between vehicle speed sensor connector and engine ground.

Connector & terminal 
(B17) No. 3 (+) - Engine ground (-): 		 Is the measured value more than 10 V? Go to step 3.  Check harness for open or short between ignition relay and vehicle speed sensor.
3 CHECK HARNESS BETWEEN VEHICLE SPEED SENSOR AND ENGINE GROUND. 
  1. Turn ignition switch to OFF.
  2. Measure resistance between vehicle speed sensor connector and engine ground.

Connector & terminal 
(B17) No. 2 - Engine ground: 		 Is the measured value less than 10 ohm? Go to step 4.  Repair wiring harness.
4 CHECK HARNESS BETWEEN VEHICLE SPEED SENSOR AND COMBINATION METER. 
  1. Disconnect connector from combination meter.
  2. Measure resistance between vehicle speed sensor harness connector and combination meter harness connector.

Connector & terminal 
(B17) No. 1 - (i10) No. 13: 		 Is the measured value less than 10 ohm? Replace vehicle speed sensor. Repair wiring harness.
