DTC P0122, P0123 TP SENSOR
DTC P0122, P0123 TP SENSOR PFP:16119
Component Description EBS010NN
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.
CONSULT-II Reference Value in Data Monitor Mode EBS010NO
Specification data are reference values.
*: Throttle position sensor 2 signal is converted by ECM internally. Thus, it differs from ECM terminal voltage signal.
On Board Diagnosis Logic EBS010NP
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 EBS010NQ
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.

MONITOR ITEM CONDITION SPECIFICATION
THRTL SEN1
THRTL SEN2*
● Ignition switch: ON
(Engine stopped)
Accelerator pedal: Fully released More than 0.36V
● Shift lever: D (A/T), 1st (M/T) Accelerator pedal: Fully depressed Less than 4.75V
DTC No. Trouble diagnosis name DTC detecting condition Possible cause
P0122
0122
Throttle position sensor 2
circuit low input
An excessively low voltage from the TP sensor 2
is sent to ECM.
● Harness or connectors
(TP sensor 2 circuit is open or
shorted.)
(APP sensor 2 circuit is shorted.)
● Electric throttle control actuator
(TP sensor 2)
● Accelerator pedal position sensor
P0123
0123
Throttle position sensor 2
circuit high input
An excessively high voltage from the TP sensor 2
is sent to ECM.
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.
