DTC P0222, P0223 TP SENSOR

PFP:16119

Component Description

NBS000RJ

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

NBS000RK

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

NBS000RL

These self-diagnoses have the one trip detection logic.

FAIL-SAFE MODE

When the malfunction is detected, ECM enters fail-safe mode and the MIL lights up.

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.)
(The 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 sen-
sor 1 is sent to ECM.

Engine operation condition in fail-safe mode

ECM controls the electric throttle control actuator in regulating the throttle opening in order for the idle position to be within +10
degrees.
ECM regulates the opening speed of the throttle valve to be slower than the normal condition.
So, the acceleration will be poor.

DTC Confirmation Procedure

NBS000RM

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-II

1.

Turn ignition switch ON.

2.

Select “DATA MONITOR” mode with CONSULT-II.

3.

Start engine and let it idle for 1 second.

4.

If DTC is detected, go to

EC-356, "Diagnostic Procedure"

.

WITH GST

Follow the procedure “WITH CONSULT-II” above.

DTC P0222, P0223 TP SENSOR

Specification data are reference values and are measured between each terminal and ground.

CAUTION:

Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

Diagnostic Procedure

NBS000RO

1.

CHECK GROUND CONNECTIONS

1.

Turn ignition switch OFF.

2.

Loosen and retighten two ground screws on the body. Refer to

EC-159, "Ground Inspection"

.

OK or NG

OK

>> GO TO 2.

NG

>> Repair or replace ground connections.
