Component Description
EBS00R0P
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
EBS00R0Q
The MI will not light up for this diagnosis.
DTC Confirmation Procedure
EBS00R0R
NOTE:
If “DTC Confirmation Procedure” has been previously conducted, always turn ignition switch “OFF” and wait at
least 10 seconds before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10V at idle.
WITH CONSULT-II
1.
Turn ignition switch “ON”.
2.
Select “DATA MONITOR” mode with CONSULT-II.
3.
Turn ignition switch “OFF”, wait at least 10 seconds.
4.
Turn ignition switch “ON”.
5.
Repeat steps 3 and 4 for 32 times.
6.
If 1st trip DTC is detected, go to
EC-800, "Diagnostic Procedure"
.
WITHOUT CONSULT-II
1.
Turn ignition switch “ON”.
2.
Turn ignition switch “OFF”, wait at least 10 seconds and then turn “ON”.
3.
Repeat step 2 for 32 times.
4.
Perform “Diagnostic Test Mode II (Self-diagnostic results)” with ECM.
5.
If 1st trip DTC is detected, go to
EC-800, "Diagnostic Procedure"
.

DTC P1227, P1228 APP SENSOR
PFP:18002
Component Description
EBS00R0U
The accelerator pedal position sensor is installed on the upper end
of the accelerator pedal assembly. The sensor detects the accelera-
tor position and sends a signal to the ECM.
Accelerator pedal position sensor has two sensors. These sensors
are a kind of potentiometers which transform the accelerator pedal
position into output voltage, and emit the voltage signal to the ECM.
In addition, these sensors detect the opening and closing speed of
the accelerator pedal and feed the voltage signals to the ECM. The
ECM judges the current opening angle of the accelerator pedal from
these signals and controls the throttle control motor based on these
signals.
Idle position of the accelerator pedal is determined by the ECM
receiving the signal from the accelerator pedal position sensor. The ECM uses this signal for the engine oper-
ation such as fuel cut.
CONSULT-II Reference Value in Data Monitor Mode
EBS00R0V
Specification data are reference values.
*: Accelerator pedal position sensor 2 signal is converted by ECM internally. Thus, it differ from ECM terminal voltage signal.
On Board Diagnosis Logic
EBS00R0W
These self-diagnoses have the one trip detection logic.
FAIL-SAFE MODE
When the malfunction is detected, the ECM enters fail-safe mode and the MI lights up.
DTC Confirmation Procedure
EBS00R0X
NOTE:
If “DTC Confirmation Procedure” has been previously conducted, always turn ignition switch “OFF” and wait at
least 10 seconds before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10V at idle.

Possible cause

Accelerator pedal position
sensor 2 circuit low input
An excessively low voltage from the APP sensor 2
is sent to ECM.
●
Harness or connectors
(The APP sensor 2 circuit is open or
shorted.)
●
Accelerator pedal position sensor
(Accelerator pedal position sensor 2)
P1228
1228
Accelerator pedal position
sensor 2 circuit high input
An excessively high voltage from the APP sensor 2
is sent to ECM.
Engine operating 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 throttle valve to be slower than the normal condition.
So, the acceleration will be poor.
