DTC P0500 VEHICLE SPEED SENSOR MALFUNCTION
CIRCUIT DESCRIPTION
The speed sensor for skid control ECU detects the wheel speed and sends the appropriate signals to the
skid control ECU.
The skid control ECU converts these signals into a 4±pulse signal and outputs it to the combination meter.
After this signal is converted into a more precise rectangular waveform by the waveform shaping circuit in-
side the combination meter, it is then transmitted to the ECM. The ECM determines the vehicle speed based
on the frequency of these pulse signals.

INSPECTION PROCEDURE
HINT:
Read freeze frame data using \f \b\f\f
 Freeze frame data records the engine conditions when
a malfunction is detected. When troubleshooting, it is useful for determi\
ning whether the vehicle was running
or stopped, the engine was warmed up or not, the air±fuel ratio was lea\
n or rich, etc. at the time of the mal-
function.
1CHECK OPERATION OF SPEEDOMETER(SPEEDOMETER OPERATION)
(a)Drive the vehicle and check that the operation of the speedometer in the\
combination meter is normal.
HINT:
The vehicle speed sensor is operating normally if the speedometer display i\
s normal.
NGCHECK SPEEDOMETER CIRCUIT
OK
2INSPECT ECM(CHECK VOLTAGE)
(a)Shift the lever to the neutral position.
(b)Jack up the vehicle.
(c)Turn the ignition switch ON.
