DTC P0122, P0123 TP SENSOR PFP:16119
Component Description
BBS004MD
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
BBS004ME
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
BBS004MF
These self-diagnoses have the one trip detection logic.
NOTE:
If DTC P0122 or P0123 is displayed with DTC P1229, first perform the trouble diagnosis for DTC P1229.
Refer to EC-1471, "
DTC P1229 SENSOR POWER SUPPLY" .
FAIL-SAFE MODE
When the malfunction is detected, ECM enters fail-safe mode and the MI lights up.

MONITOR ITEM CONDITION SPECIFICATION
THRTL SEN 1
THRTL SEN 2*
Ignition switch: ON
(Engine stopped)
Shift lever: D (A/T), 1st (M/T)
Accelerator pedal: Fully released More than 0.36V

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.)
Electric throttle control actuator
(TP sensor 2)
P0123
0123
Throttle position sensor
2 circuit high input
An excessively high voltage from the TP sen-
sor 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.
