DTC P0500: Vehicle Speed Sensor "A" [12/2013 - 11/2016]: Procedure

1. Drive the vehicle and check whether the operation of the speedometer in the combination meter assembly is normal.

   HINT: 

   • The vehicle speed sensor is operating normally if the speedometer reading is normal.
   • If the speedometer does not operate, check it by following the procedure described for a speedometer malfunction.
2. Connect the Techstream to the DLC3.
3. Turn the ignition switch to ON.
4. Turn the Techstream on.
5. Enter the following menus: Powertrain / ECT / Data List / Vehicle Speed.

   Powertrain > ECT > Data List 

   Tester Display

   1. Move the shift lever to N.
   2. Jack up the vehicle.
   3. Turn the ignition switch to ON.
   4. Measure the voltage between the terminal of the combination meter assembly and the body ground while the wheel is turned slowly.

      Standard Voltage

      Tester Connection	Condition	Specified Condition
      F22-3 (+S) - Body ground	Ignition switch ON	Voltage generated intermittently

      HINT: 

      The output voltage should fluctuate up and down, similarly to the diagram, when the wheel is turned slowly.
