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 pulse signal and outputs it to the ECM via the combination meter. The ECM determines the vehicle speed based on the frequency of this pulse signal.

DTC No.
DTC Detection Condition
Trouble Area
P0500
While the vehicle is being driven, no vehicle speed 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 assembly
  4. ECM
  5. Skid control ECU

MONITOR DESCRIPTION

Automatic Transaxle Models:
  1. The ECM assumes that the vehicle is being driven when the vehicle speed signal from the transmission (SP2) indicates a speed of 9 km/h (6 mph) or more.
    If there is no vehicle speed signal from the combination meter (SP1) for 5 seconds when the vehicle is being driven, the ECM determines this to be a malfunction of the vehicle speed sensor. The ECM then illuminates the MIL and stores the DTC.
Manual Transaxle Models:
  1. The ECM assumes that the vehicle is being driven when the idle fuel-cut operation* is being executed. If there is no signal from the vehicle speed sensor despite this condition being met, the ECM interprets this as a malfunction in the speed signal circuit. The ECM then illuminates the MIL and stores the DTC.
    *: Idle fuel-cut is executed when the throttle valve is fully closed and engine speed is over 2500 rpm.

INSPECTION PROCEDURE

HINT:
Read freeze frame data using the GTS. 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.

2.READ VALUE USING GTS (VEHICLE SPEED)

  1. Connect the GTS to the DLC3.

  1. Turn the ignition switch to ON.

  1. Turn the GTS on.

  1. Enter the following menus: Powertrain / Engine and ECT / Data List / All Data / Vehicle Speed.

  1. Drive the vehicle.

  1. Read the value displayed on the GTS.

    OK:
    Vehicle speeds displayed on the GTS and speedometer display are equal.

    Tester Connection
    		Condition
    		Specified Condition
    E7-4 (+S) - A38-13 (SPD)
    		Always
    		Below 1 Ω
    E7-4 (+S) or A38-13 (SPD) - Body ground
    		Always
    		10 kΩ or higher

    		Always
    		Below 1 Ω
    E7-4 (+S) or A52-13 (SPD) - Body ground
    		Always
    		10 kΩ or higher
    HINT:
    If the wire harness has a short, check the speed signal circuit in other systems related to the vehicle speed signal (e.g. tire pressure warning system, audio system, etc.).

  1. Disconnect the combination meter assembly connector.

    HINT:
    Disconnect the ECU connectors of other systems related to the speed signal, but do not disconnect the ECM connectors.

  1. Turn the ignition switch to ON.

  1. Measure the voltage according to the value(s) in the table below.

    Standard Voltage:
    Tester Connection
