Title: 2GR-FE (ENGINE CONTROL): SFI SYSTEM: P0500; Vehicle Speed Sensor; 2016 MY Sienna [12/2015 - 08/2016]

DTC

P0500

Vehicle Speed Sensor

DESCRIPTION

The wheel speed sensors monitor the wheel rotation speed and send signals 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 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 in the wiring diagram below will not operate normally.

DTC No.

DTC Detection Condition

Trouble Area

P0500

While vehicle being driven, no vehicle speed sensor signal transmitted to ECM (1 trip detection logic).
  • Open or short in speed signal circuit
  • Combination meter assembly
  • ECM

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 the DTC.

CONFIRMATION DRIVING PATTERN

  1. Connect the Techstream to the DLC3.
  2. Turn the ignition switch to ON and turn the Techstream on.
  3. Clear DTCs (even if no DTCs are stored, perform the clear DTC procedure) (See page 2016 MY Sienna [12/2015 - 08/2016]; 2GR-FE (ENGINE CONTROL): SFI SYSTEM: DTC CHECK / CLEAR ).
  4. Turn the ignition switch off.
  5. Turn the ignition switch to ON and turn the Techstream on [A].
  6. Start the engine.
  7. Drive the vehicle at 24 km/h (15 mph) or more for a total of 30 seconds or more [B].

    CAUTION:

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

  8. Stop the vehicle.
  9. Enter the following menus: Powertrain / Engine / Utility / All Readiness.
  10. Input the DTC: P0500.
  11. Check the DTC judgment result [C].

    Techstream Display

    Description

    NORMAL
    • DTC judgment completed
    • System normal

    ABNORMAL
    • DTC judgment completed
    • System abnormal

    INCOMPLETE
    • DTC judgment not completed
    • Perform driving pattern after confirming DTC enabling conditions

    N/A
    • Unable to perform DTC judgment
    • Number of DTCs which do not fulfill DTC preconditions has reached ECU's memory limit

    HINT:

    If the judgment result shows ABNORMAL, the system has a malfunction.

  12. If the test result is N/A, enter the following menus: Powertrain / Engine / Trouble Codes.
  13. Read Pending DTCs.

    HINT:

    If a pending DTC is output, the system is malfunctioning.

  14. If the test result is INCOMPLETE or N/A and no pending DTC is output, perform a universal trip and check for permanent DTCs (See page 2016 MY Sienna [12/2015 - 08/2016]; 2GR-FE (ENGINE CONTROL): SFI SYSTEM: DTC CHECK / CLEAR ).

    HINT:

    • If a permanent DTC is output, the system is malfunctioning.
    • If no permanent DTC is output, the system is normal.

WIRING DIAGRAM

CAUTION / NOTICE / HINT

HINT:

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.

PROCEDURE

1.

READ VALUE USING TECHSTREAM (VEHICLE SPEED)

(a) 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.
  • If the speedometer does not operate, check it by following the procedure described for a speedometer malfunction.

(b) Connect the Techstream to the DLC3.

(c) Turn the ignition switch to ON.

(d) Turn the Techstream on.

(e) Enter the following menus: Powertrain / Engine / Data List / Vehicle Speed.

(f) Drive the vehicle.

(g) Read the value displayed on the Techstream.

2.

CHECK COMBINATION METER SYSTEM (SPEED SIGNAL CIRCUIT)

(a) Inspect the circuits that send vehicle speed signals to this system in the meter system (See page 2016 MY Sienna [12/2015 - 08/2016]; METER / GAUGE / DISPLAY: METER / GAUGE SYSTEM: Speed Signal Circuit ).
