5.CHECK FOR INTERMITTENT PROBLEMS
Hand±held tester only:
By putting the vehicle's ECM in the check mode, the 1 trip detection logic is possible instead \
of the 2 trip
detection logic, and the sensitivity to detect faults is increased. This\
makes it easier to detect intermittent
problems.
(a)Clear the DTCs (See step 2).
(b)Set the check mode (See step 3).
(c)Perform a simulation test (See page 01±22).
(d)Check the connector and terminal (See page 01±32).
(e)Wiggle the harness and the connector (See page 01±32).
6. DATA LIST
HINT:
Using the DATA LIST displayed by the hand±held tester, you can read the value of the switches, sensors,
actuators and so on without parts removal. Reading the DATA LIST as a first step of troubleshooting is one
method to shorten diagnostic time.
NOTICE:
The values given below for ºNormal Conditionº are representative valu\
es. A vehicle may still be nor-
mal even if its value differs from those listed here. So, do not solely dep\
end on the ºNormal Condi-
tionº here when deciding whether a part is faulty or not.
(a) Warm up the engine.
(b) Turn the ignition switch OFF.
(c) Connect the hand±held tester to the DLC3.
(d) Turn the ignition switch ON.
(e) Push the ºONº button of the hand±held tester.
(f) Select the item ºDIAGNOSIS / OBD/MOBD / DATA LISTº.
(g) According to the display on tester, read the ºDATA LISTº.

CIRCUIT DESCRIPTION
HINT:

This electrical throttle system is no used throttle cable.

This throttle position sensor is non±contact type.
The throttle position sensor is mounted on the throttle body to detect the opening angle of the throttle valve.
Since this sensor is electronically controlled with hall elements, accurate control and reliability can be ob-
tained. It has 2 sensors to detect the throttle opening angle and a malfunction of the throttle position sensor.
The voltage is applied to the terminals VTA1 and VTA2 of the ECM changes between 0 V and 5 V in propor-
tion to the opening angle of the throttle valve. The VTA1 is a signal to indicate the actual throttle valve open-
ing angle which is used for the engine control, and the VTA2 is a signal to indicate the information about the
opening angle which is used for detecting a malfunction.
The ECM judges the current opening angle of the throttle valve from these signals input from terminals VTA1
and VTA2, and the ECM controls the throttle motor to make the throttle valve angle properly in response to
the driving condition.

CIRCUIT DESCRIPTION
HINT:
This electrical throttle system is no used throttle cable.
The accelerator pedal position sensor is mounted on the accelerator pedal bracket and it have the 2 sensors
to detect the accelerator position and a malfunction of the accelerator position sensor.
In the accelerator pedal position sensor, the voltage applied to VPA1 and VPA2 of the ECM changes be-
tween 0 V and 5 V in proportion to the opening angle of the accelerator pedal. The VPA1 is a signal to indicate
the actual accelerator pedal opening angle which is used for the engine control, and the VPA2 is a signal
to indicate the information about VPA1 which is used for detecting a malfunction in VPA1.
The ECM monitors the current opening angle of the accelerator pedal from these signals input from VPA1
and VPA2, and controls the throttle motor based on these signals.

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.

INSPECTION PROCEDURE
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 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.
