DTC P0500 Vehicle Speed Sensor "A"


DESCRIPTION

The vehicle speed sensor outputs 4 pulses 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 this pulse signal.

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.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 intelligent tester on.

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

  1. Drive the vehicle.

  1. Read the value displayed on the intelligent tester.

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

Go to step 2
OK

2.CHECK COMBINATION METER SYSTEM

  1. Inspect the circuits that send vehicle speed signals to this system in the meter system (HILUX_TGN26 RM000002UD705SX.html).

  1. During inspection for the meter section, if there is an instruction that indicates to go back to inspections for each system, proceed to the next step.

3.CHECK HARNESS AND CONNECTOR (ECM - COMBINATION METER)

  1. Disconnect the ECM connector.

  1. Disconnect the combination meter connector.

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

    Standard Resistance:

    Tester Connection
    		Condition
    		Specified Condition
    G19-6 (+S) - G146-16 (SPD)
    		Always
    		Below 1 Ω


NG
Go to step 4
OK

REPLACE ECM (HILUX_TGN26 RM000000VW2023X.html)

4.CHECK HARNESS AND CONNECTOR (ECM - JUNCTION CONNECTOR)

  1. Disconnect the ECM connector.

  1. Disconnect the junction connector.

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

    Standard Resistance:

    Tester Connection
    		Condition
    		Specified Condition
    2P-26 - G146-16 (SPD)
    		Always
    		Below 1 Ω
