DTC P0500 Vehicle Speed Sensor "A"


DESCRIPTION

The speed sensor detects the wheel speed and sends the appropriate signals to the skid control ECU. The skid control ECU converts these wheel speed signals into a 4-pulse signal and outputs it to the ECM via the combination meter. The ECM determines the vehicle speed based on the frequency of these pulse signals.

DTC Code
DTC Detection Condition
Trouble Area
P0500
While the vehicle is being driven, no vehicle speed sensor signal is transmitted to the ECM (2 trip detection logic).
  1. Open or short in speed signal circuit
  2. Wheel speed sensor
  3. Combination meter
  4. ECM
  5. Skid control ECU

MONITOR DESCRIPTION

The ECM assumes that the vehicle is being driven when the indicated vehicle speed is more than 9 km/h (5.6 mph). If there is no speed signal from the combination meter despite these conditions being met, the ECM interprets this as a malfunction in the speed signal circuit. The ECM then illuminates the MIL and stores the DTC.

INSPECTION PROCEDURE

HINT:
Read freeze frame data using the intelligent tester. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.
1.CHECK OPERATION OF SPEEDOMETER
  1. Drive the vehicle and check whether the operation of the speedometer in the combination meter is normal.

    HINT:
    1. The vehicle speed sensor is operating normally if the speedometer reading is normal.
    2. If the speedometer does not operate, check it by following the procedure described in Speedometer Malfunction (Click here).

2.READ VALUE USING INTELLIGENT TESTER (VEHICLE SPD)
  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch to ON.

  1. Turn the intelligent tester on.

  1. Enter the following menus: Powertrain / ECT / Data List.

  1. Drive the vehicle.

  1. According to the display on the tester, read the Data List.
