Component Description
INFOID:0000000005273852
Electric throttle control actuator consists of throttle control motor,
throttle position sensor, etc. The throttle position sensor responds to
the throttle valve movement.
The throttle position sensor has the two sensors. These sensors are
a kind of potentiometers which transform the throttle valve position
into output voltage, and emit the voltage signal to the ECM. In addi-
tion, these sensors detect the opening and closing speed of the
throttle valve and feed the voltage signals to the ECM. The ECM
judges the current opening angle of the throttle valve from these sig-
nals and the ECM controls the throttle control motor to make the
throttle valve opening angle properly in response to driving condi-
tion.
On Board Diagnosis Logic
INFOID:0000000005273853
This self-diagnosis has the one trip detection logic.
FAIL-SAFE MODE
When the malfunction is detected, the ECM enters fail-safe mode and the MIL illuminates.
DTC Confirmation Procedure
INFOID:0000000005273854
NOTE:
If DTC Confirmation Procedure has been previously conducted, always perform the following before conduct-
ing the next step.
1.
Turn ignition switch OFF and wait at least 10 seconds.
2.
Turn ignition switch ON.
3.
Turn ignition switch OFF and wait at least 10 seconds.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10V at idle.
1.
Start engine and let it idle for 1 second.
2.
Check DTC.
3.
If DTC is detected, go to
.
Diagnosis Procedure
INFOID:0000000005273855
1.
CHECK GROUND CONNECTIONS
1.
Turn ignition switch OFF.
2.
Loosen and retighten three ground screws on the body.

Throttle position sensor
circuit range/perfor-
mance
Rationally incorrect voltage is sent to ECM
compared with the signals from TP sensor 1
and TP sensor 2.
• Harness or connector
(The TP sensor 1 or 2 circuit is open or
shorted.)
(The APP sensor 2 circuit is shorted).
• Electric throttle control actuator
(TP sensor 1 or 2)
• Accelerator pedal position sensor
(APP sensor 2)
Engine operation condition in fail-safe mode
The ECM controls the electric throttle control actuator in regulating the throttle opening in order for the idle position to be within +10
degrees.
The ECM regulates the opening speed of the throttle valve to be slower than the normal condition.
So, the acceleration will be poor.
