DTC P0500: Vehicle Speed Sensor [09/2013 - ]: Procedure

1. Drive the vehicle and check whether the operation of the speedometer in the combination meter 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 in speedometer malfunction. Refer to Speedometer Malfunction [09/2013 - ] .

OK: Go to next step 

1. Connect the Techstream to the DLC3.
2. Turn the engine switch on (IG).
3. Turn the Techstream on.
4. Enter the following menus: Powertrain / Engine / Data List / Vehicle Speed.
5. Drive the vehicle.
6. Read the value displayed on the tester.

   OK

   Vehicle speeds displayed on tester and speedometer display are equal.

2. Disconnect the A14 ECM connector.
3. Measure the resistance according to the value(s) in the table below.

   Standard resistance (Check for open)

   Tester Connection	Condition	Specified Condition
   L10-10 (+S) - A14-24 (SPD)	Always	Below 1 Ω

   Standard resistance (Check for short)

   Tester Connection	Condition	Specified Condition
   L10-10 (+S) or A14-24 (SPD) - Body ground	Always	10 kΩ or higher

   HINT: 

   If the wire has a short, check the speed signal circuit in other systems related to the vehicle speed signal (e.g. the navigation system, audio system, etc.).

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR (FOR OTHER SYSTEMS RELATED TO SPEED SIGNAL)

2. Jack up the vehicle.
3. Turn the engine switch on (IG).
4. Measure the voltage according to the value(s) in the table below.

   Standard voltage

   Tester Connection	Condition	Specified Condition
   L10-10 (+S) - Body ground	Engine switch on (IG) Wheel turned slowly	Voltage generated intermittently

   HINT: 

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