DTC P1223, P1224 TP SENSOR

PFP:16119

Component Description

EBS00QRZ

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

EBS00QS0

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

EBS00QS1

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

EBS00QS2

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

P1223
1223

Throttle position sensor 2
circuit low input

An excessively low voltage from the TP sensor 2
is sent to ECM.

●

Harness or connectors
(The TP sensor 2 circuit is open or
shorted.)

●

Electric throttle control actuator
(TP sensor 2)

P1224
1224

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.
