DTC P0500 Vehicle Speed Sensor "A"


DESCRIPTION

The vehicle speed sensor outputs a 4 pulse signal for every revolution of the rotor shaft, which is rotated by the transmission output shaft via the driven gear. After this signal is converted into a more precise rectangular waveform by the waveform shaping circuit inside the combination meter, it is then transmitted to the ECM. The ECM determines the vehicle speed based on the frequency of these pulse signals.

DTC No.
DTC Detection Condition
Trouble Area
P0500
While vehicle is being driven, no vehicle speed sensor signal input to ECM
(2 trip detection logic)
  1. Open or short in speed sensor circuit
  2. Vehicle speed sensor
  3. Combination meter
  4. ECM

MONITOR DESCRIPTION

  1. for Automatic Transmission
    The ECM assumes that the vehicle is being driven when the Park/Neutral Position (PNP) switch is OFF while 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.
  1. for Manual Transmission
    The ECM assumes that the vehicle is being driven when the indicated engine speed is 2000 to 5000 rpm and the engine load calculated by the ECM is more than a certain level. If there is no signal from the vehicle speed sensor, 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 conditions when a malfunction is detected. When troubleshooting, freeze frame data can help determine if the vehicle was running or stopped, 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 INTELLIGENT TESTER (VEHICLE SPEED)

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch to ON.

  1. Turn the tester 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 tester.

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

  1. Disconnect the combination meter connector.

  1. Disconnect the ECM connector.

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

    Standard resistance:
    Tester Connection
    		Specified Condition
    C27-6 - E5-17 (SPD)
    		Below 1 Ω
    C27-6 or E5-17 (SPD) - Body ground
    		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. tire pressure warning system, audio system, etc.).

  1. Disconnect the combination meter connector.

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

  1. Turn the ignition switch to ON.

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