DTC P0500: Vehicle Speed Sensor "A": Procedure

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

   OK

   The operation of the speedometer 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 toSpeedometer Malfunction .

OK: Go to next step 

1. Connect the Techstream to the DLC3.
2. Turn the ignition switch to ON.
3. Turn the Techstream on.
4. Enter the following menus: Powertrain / Engine and ECT / Data List / Vehicle Speed.
5. Drive the vehicle.
6. Read the value displayed on the Techstream.

   OK

1. Move the shift lever to neutral position.
2. Jack up the vehicle.
3. Turn the ignition switch to ON.
4. Measure the voltage according to the value(s) in the table below.

   Standard Voltage

   Tester Connection	Switch Condition	Specified Condition
   E78-18 (SPD) - B49-12 (E1)	Ignition switch ON (turn wheel slowly)	Voltage generated intermittently

   *1	Component with harness connected (ECM)

   HINT: 

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

NG → See step   8 

OK: Go to next step 

1. Disconnect the combination meter connector.
2. Disconnect the 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
   E13-14 (+S) - E78-18 (SPD)	Always	Below 1 Ω

   Standard Resistance (Check for Open)

   Tester Connection	Condition	Specified Condition
   E13-14 (+S) or E78-18 (SPD) - Body ground	Always	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
