P0500 | Vehicle Speed Sensor "A" |
DESCRIPTION
Vehicles, which are equipped with the VSC (Vehicle Stability Control) system, detect the vehicle speed using the skid control ECU and wheel speed sensor. 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 TCM via the combination meter. The TCM determines the vehicle speed based on the frequency of the pulse signal.

When DTC P0500 is output, a ground short in the wiring of terminal SPD or an internal ground short in the relevant ECU is suspected.
PROCEDURE
READ VALUE USING GTS (VEHICLE SPEED)
Connect the GTS to the DLC3.
Turn the ignition switch to ON.
Turn the GTS on.
Enter the following menus: Powertrain / Multi-Mode M/T / Data List / Vehicle Speed.
Drive the vehicle.
According to the display on the GTS, read the Data List.

Component with harness connected (Combination Meter Assembly) |
Remove the combination meter assembly with the connector still connected.
Connect an oscilloscope to terminals E46-6 (+S) and body ground.
Turn the ignition switch to ON.
Turn the wheel slowly.
Check the signal waveform according to the condition in the table below.
Item | Condition |
---|---|
Tool setting | 5 V/DIV., 20 ms/DIV. |
Vehicle condition | Driving at approx. 20 km/h (12 mph) |
OK |
