DTC P0500 Vehicle Speed Sensor "A"


​

DESCRIPTION

The wheel speed sensor monitors the wheel rotation speed and sends a signal to the skid control ECU. The skid control ECU converts the wheel speed signal into a 4-pulse signal and transmits it to the ECM via the combination meter. The ECM determines the vehicle speed based on the frequency of the pulse signal.

Connect the intelligent tester to the DLC3. Camry


INSPECTION PROCEDURE

HINT:
Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. 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 the ON position.

  1. Turn the tester on.

  1. Select the following menu items: Powertrain / Engine and ECT / 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 (Click here).

  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.

3.CHECK HARNESS AND CONNECTOR (COMBINATION METER ASSEMBLY - ECM)
  1. Disconnect the A24 ECM connector. Camry

  2. Disconnect the A24 ECM connector.

  1. Disconnect the F2 combination meter connector.

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

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

  1. Reconnect the ECM connector.

  1. Reconnect the combination meter connector.

4.CHECK HARNESS AND CONNECTOR (ECM - NO. 3 JUNCTION BLOCK)

  1. Disconnect the A24 ECM connector.


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

  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):
    Tester Connection
    		Condition
    		Specified Condition
    3B-10 - SPD (A24-8)
    		Always
    		Below 1 Ω

  1. Reconnect the ECM connector.

  1. Reconnect the No. 3 junction block connector.
