DTC P0122, P0123 APP SENSORPFP:18002
DescriptionEBS0118W
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 ModeEBS0118X
Specification data are reference values.
*: These signals are converted by ECM internally. Thus, these differ from ECM terminals voltage.
On Board Diagnosis LogicEBS0118Z
These self-diagnoses have the one trip detection logic.
MI will not light up for these self-diagnoses.
NOTE:

If DTC P0122 or P0123 is displayed with DTC P0642 or P0643, first perform trouble diagnosis for
DTC P0642 or P0643. Refer to EC-1236, "
DTC P0642, P0643 SENSOR POWER SUPPLY" .
DTC Confirmation ProcedureEBS01190
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-1103, "

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.
