DTC P0222, P0223 APP SENSOR

DTC P0222, P0223 APP SENSORPFP:18002
DescriptionEBS011A6
The accelerator pedal position sensor is installed on the upper end
of the accelerator pedal assembly. The sensors detect the accelera-
tor pedal position and sends a signal to the ECM. The ECM uses the
signal to determine the amount of fuel to be injected.
CONSULT-II Reference Value in Data Monitor ModeEBS011A7
Specification data are reference values.
*: These signals are converted by ECM internally. Thus, these differ from ECM terminals voltage.
On Board Diagnosis LogicEBS011A9
These self-diagnoses have the one trip detection logic.
MI will not light up for these self-diagnoses.
NOTE:

If DTC P0222 or P0223 is displayed with DTC P0652 or P0653, first perform trouble diagnosis for
DTC P0652 or P0653. Refer to EC-1240, "
DTC P0652, P0653 SENSOR POWER SUPPLY" .
DTC Confirmation ProcedureEBS011AA
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.
WITH CONSULT-II
1. Turn ignition switch ON.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Wait at least 5 seconds.
4. If DTC is detected, go to EC-1142, "
Diagnostic Procedure" .

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.

DTC P0234 TC SYSTEMPFP:14411
DescriptionEBS011AF
The load from the turbocharger boost control solenoid valve controls
the actuator. By changing the variable nozzle vane opening through
the rods, the intake air volume is adjusted.
The turbocharger boost control solenoid valve is moved by ON/OFF
pulse from the ECM. The longer the ON pulse, the charge air pres-
sure rises.
On Board Diagnosis LogicEBS011AI
These self-diagnoses have the one trip detection logic.
The MI will not light up for these self-diagnoses.
NOTE:

If DTC P0234 is displayed with DTC P0652 or P0653, first perform trouble diagnosis for DTC P0652
or P0653. Refer to EC-1240, "
DTC P0652, P0653 SENSOR POWER SUPPLY" .
Overall Function CheckEBS011AJ
Use this procedure to check the overall function of the turbocharger. During this check, a DTC might not be
confirmed.
1. Start engine and let it idle.
2. Make sure that turbocharger control actuator rod moves slightly
when engine is started.
3. If NG, go to EC-1147, "
Diagnostic Procedure" .
