Component Description

INFOID:0000000005273177

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:0000000005273178

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 MIL lights up.

DTC Confirmation Procedure

INFOID:0000000005273179

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 8V at idle.

 WITH CONSULT-III

1.

Start engine and let it idle for 1 second.

2.

Check DTC.

3.

If DTC is detected, go to 

EC-184, "Diagnosis Procedure"

.

 WITH GST

Follow the procedure “WITH CONSULT-III” above.

Diagnosis Procedure

INFOID:0000000005273180

1.

CHECK GROUND CONNECTIONS

1.

Turn ignition switch OFF.

PBIB0145E

DTC No.

Trouble diagnosis name

DTC detecting condition

Possible cause

P0222
0222

Throttle position sensor 1 
circuit low input

An excessively low voltage from the TP 
sensor 1 is sent to ECM.

• Harness or connectors

(The TP sensor 1 circuit is open or shorted.)
(APP sensor 2 circuit is shorted.)

• Electric throttle control actuator

(TP sensor 1)

• Accelerator pedal position sensor

(APP sensor 2)

P0223
0223

Throttle position sensor 1 
circuit high input

An excessively high voltage from the TP 
sensor 1 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.
