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.

   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.

NG → See step   10 

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 Techstream.

   OK

   Vehicle speeds displayed on the Techstream and speedometer display are equal.

OK → See step   9 

1. Disconnect the combination meter assembly 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
   J34-5 (+S) - A5-30 (SPD)	Always	Below 1 Ω

4. Reconnect the combination meter assembly connector.
5. Reconnect the ECM connector.

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR (COMBINATION METER ASSEMBLY - ECM)

1. Disconnect the combination meter assembly connector.

   HINT: 

   Disconnect the ECU connectors on the other systems related to the speed signal (but the ECM connectors must be connected).

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

   Standard Voltage

   Tester Connection	Condition	Specified Condition
   J34-5 (+S) - Body ground	Engine switch on (IG)	4.5 to 5.5 V

1. Remove the combination meter assembly.
2. Connect the combination meter assembly connector.
3. Move the shift lever to N.
4. Jack up the vehicle.
5. Turn the engine switch on (IG).
6. Check 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
   J34-5 (+S) - Body ground	Engine switch on (IG) (Turn wheel slowly)	Voltage generated intermittently

   HINT: 

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

7. Reinstall the combination meter assembly.

OK → See step   11 

1. Disconnect the combination meter assembly connector.
2. Disconnect the brake actuator connector.
3. Measure the resistance according the value(s) in the table below.

   Standard Resistance (Check for Open)

   Tester Connection	Condition	Specified Condition
   J34-17 (SI) - A58-11 (SP1)	Always	Below 1 Ω

   Standard Resistance (Check for Short)

   Tester Connection	Condition	Specified Condition
