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.

INSPECTION PROCEDURE

NOTICE:
  1. Inspect the fuses of circuits related to this system before performing the following inspection procedure.
  2. After replacing the ECM, the new ECM needs registration (HILUX_TGN26 RM0000012XK07EX.html) and initialization (HILUX_TGN26 RM000000TIN056X.html).
  3. After replacing the fuel supply pump assembly, the ECM needs initialization (HILUX_TGN26 RM000000TIN056X.html).
  4. After replacing an injector assembly, the ECM needs registration (HILUX_TGN26 RM0000012XK07EX.html).
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, 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 assembly is normal.

    HINT:
    The vehicle speed sensor is operating normally if the speedometer reading is normal.
    OK:
    The vehicle speed sensor is operating normally.


NG
Go to step 7
OK


2.READ VALUE USING INTELLIGENT TESTER (VEHICLE SPEED)

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch to ON and start the engine.

  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 speed displayed on tester and speedometer display are equal.


OK
Go to step 10

NG
Go to step 3

3.CHECK HARNESS AND CONNECTOR

  1. Disconnect the combination meter assembly connector.

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

    Standard Voltage:
    Tester Connection
    		Switch Condition
    		Specified Condition
    G19-6 (+S) - Body ground
    		Ignition switch ON
    		4.5 to 5.5 V

  1. Move the shift lever to neutral.

  1. Jack up the vehicle.

  1. Check the voltage between the terminal of the combination meter assembly and the body ground while a wheel is turned slowly.

    Standard Voltage:
    Tester Connection
    		Switch Condition
    		Specified Condition
    G19-6 (+S) - Body ground
    		Ignition switch ON
    		Voltage generated intermittently

    		Component with harness connected
    (Combination Meter Assembly)
    HINT:
    The output voltage should fluctuate up and down, similarly to the diagram, when the wheel is turned slowly.


OK
Go to step 6

NG
Go to step 8

5.CHECK HARNESS AND CONNECTOR (COMBINATION METER ASSEMBLY - ECM)

  1. Disconnect the combination meter assembly connector.

  1. Disconnect the ECM connector.

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

    Standard Resistance:

    Tester Connection
    		Condition
    		Specified Condition
    G19-6 (+S) - G148-30 (SPD)
    		Always
    		Below 1 Ω
    G19-6 (+S) or G148-30 (SPD) - Body ground
    		Always
    		10 kΩ or higher

  1. Reconnect the combination meter assembly connector.

  1. Reconnect the ECM connector.

Go to step 9
OK


6.REPLACE ECM

  1. Replace the ECM (HILUX_TGN26 RM0000013Z001IX.html).



NEXT
Go to step 10

7.CHECK SPEEDOMETER CIRCUIT

  1. Check the speedometer circuit (HILUX_TGN26 RM0000011IY01VX.html).
