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.

INSPECTION PROCEDURE

HINT:
Read freeze frame data using the intelligent tester or the OBD II scan tool. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air-fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction (CAMRY_ACV40 RM000000PDS01FX.html).
1.READ VALUE USING INTELLIGENT TESTER (VEHICLE SPEED)

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch to the ON position.

  1. Turn the tester on.

  1. Select the following menu items: Powertrain / Engine / Date List / 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.

2.CHECK COMBINATION METER SYSTEM

  1. The circuits that send vehicle speed signals to this system are inspected in the meter system (CAMRY_ACV40 RM000002UD701TX.html).

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

  1. Disconnect the A24 or A55 ECM connector.

  1. Disconnect the F2 combination meter connector.

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

    Standard resistance (Check for open):
    RHD:
    Tester Connection
    		Specified Condition
    +S (F2-12) - SPD (A24-8)
    		Below 1 Ω
    LHD:
    Tester Connection
    		Specified Condition
    +S (F2-12) - SPD (A55-8)
    		Below 1 Ω

    Standard resistance (Check for short):
    RHD:
    Tester Connection
    		Specified Condition
    +S (F2-12) or SPD (A24-8) - Body ground
    		10 kΩ or higher
    LHD:
    Tester Connection
    		Specified Condition
    +S (F2-12) or SPD (A55-8) - Body ground
    		10 kΩ or higher

  1. Reconnect the ECM connector.

  1. Reconnect the combination meter connector.

  1. Disconnect the 3B No. 3 junction block connector.

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

    Standard resistance (Check for open):
    RHD:
    Tester Connection
    		Specified Condition
    3B-10 - SPD (A24-8)
    		Below 1 Ω
    LHD:
    Tester Connection
    		Specified Condition
    3B-10 - SPD (A55-8)
    		Below 1 Ω

  1. Reconnect the ECM connector.

  1. Reconnect the No. 3 junction block connector.
