DTC P0500 VEHICLE SPEED SENSOR ºAº
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.

DTC P0443 EVAPORATIVE EMISSION CONTROL
SYSTEM PURGE CONTROL VALVE CIRCUIT
CIRCUIT DESCRIPTION
To reduce HC emissions, evaporated fuel from the fuel tank is routed through the charcoal canister to the
intake manifold for combustion in the cylinders.
The ECM changes the duty signal to the VSV for the EVAP so that the intake quantity of HC emissions is
appropriate for the driving conditions (engine load, engine speed, vehicle speed, etc.) after the engine is
warmed up.

ECM POWER SOURCE CIRCUIT
CIRCUIT DESCRIPTION
When the ignition switch is turned ON, battery positive voltage is applied to terminal IGSW of the ECM and
the EFI relay (Marking: EFI) control circuit in the ECM sends a signal to terminal MREL of the ECM switching
on the EFI relay.
This signal causes current to flow to the coil, closing the contacts of the EFI relay and supplying power to
terminals +B and +B2 of the ECM.
If the ignition switch is turned off, the ECM continues to switch on the EFI relay for maximum 2 seconds for
the initial setting of the throttle valve.

HINT:
Read freeze frame data using the hand±held tester. Freeze frame data records the engine conditions when
a malfunction is detected. When troubleshooting, it is useful for determining whether the vehicle was running
or stopped, the engine was warmed up or not, the air±fuel ratio was lean or rich, etc. at the time of the mal-

DTCP2119THROTTLE ACTUATOR CONTROL THROTTLE BODY RANGE/PERFORMANCE
CIRCUIT DESCRIPTION
The Electric Throttle Control System (ETCS) is composed of the throttle m\
otor that operates the throttle
valve, the throttle position sensor that detects the opening angle of the throttle valve, the accelerator pedal
position sensor that detects the accelerator pedal position, the ECM that contro\
ls the ETCS, and the one
valve type throttle body.
The ECM controls the throttle motor to provide the proper throttle valve\
opening angle in response to the
driving condition.
The throttle position sensor which is mounted on the throttle body detects \
the opening angle of the throttle
valve, and it provides feedback to the ECM to control the throttle motor.
If the ETCS has a malfunction, the ECM shuts down the power for the throttle motor, and the throttle valve
is closed by the return spring. And the throttle valve is locked at a ce\
rtain opening angle. Also, the whole
electronically controlled throttle operation is cancelled until the system returns to normal and the ignition
switch is turned OFF.
