Vehicle Speed Sensor

DESCRIPTION

  • w/ Smart Key System
    • Vehicles, which are equipped with ABS (Anti-lock Brake System), detect the vehicle speed using the skid control ECU (brake actuator assembly) and speed sensor. The speed sensor monitors the wheel rotation speed and sends a signal to the skid control ECU. The skid control ECU detects the wheel speed of all 4 wheels and outputs a 4-pulse signal to the ECM via the certification ECU (smart key ECU assembly) and combination meter assembly. The ECM determines the vehicle speed based on the frequency of the pulse signal.
  • w/o Smart Key System:
    • Vehicles, which are equipped with ABS (Anti-lock Brake System), detect the vehicle speed using the skid control ECU (brake actuator assembly) and speed sensor. The 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 assembly. The ECM determines the vehicle speed based on the frequency of the pulse signal.

HINT:

  • Various systems use the vehicle speed signal distributed from the combination meter assembly. Check all the components possibly related to the speed signal.
  • A voltage of 12 V or 5 V is output from each ECU and then input to the combination meter assembly.

    The signal is changed to a pulse signal at the transistor in the combination meter assembly. Each ECU controls the respective system based on the pulse signal.

  • If a short occurs in any of the ECUs or in the wire harness connected to an ECU, all systems using the speed signal will not operate normally.

DTC No.

Vehicle Speed Sensor

While vehicle is being driven, no vehicle speed sensor signal is sent to the ECM.

(1 trip detection logic: for CVT models)

(2 trip detection logic: for Manual Transaxle models)
  • Open or short in speed signal circuit
  • Combination meter assembly
  • ECM

DTC stored

MONITOR DESCRIPTION

If there is no speed signal from the combination meter assembly even though the ECM determines that the vehicle is being driven, the ECM interprets this as a malfunction in the speed signal circuit. The ECM then illuminates the MIL and stores this DTC.

  6. Turn the ignition switch to ON [A].
  7. Turn the Techstream on.
  8. Start the engine.
  9. Drive the vehicle at 75 km/h (47 mph) or more for a total of 10 seconds or more [B].

    CAUTION:

    When performing the confirmation driving pattern, obey all speed limits and traffic laws.

  10. Stop the vehicle.
  11. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes [C].
  12. Read the pending DTCs.

    HINT:

    • If a pending DTC is output, the system is malfunctioning.
    • If a pending DTC is not output, perform the following procedure.
  13. Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
  14. Input the DTC: P0500.

Read Freeze Frame Data using the Techstream. 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.
