TROUBLE DIAGNOSIS

Basic InspectionEBS011XF
Precaution:
Perform Basic Inspection without electrical or mechanical loads applied;

Headlamp switch is OFF.

On vehicles equipped with daytime light systems, set lighting switch to the 1st position to light
only small lamps.

Air conditioner switch is OFF.

Rear defogger switch is OFF.

Steering wheel is in the straight-ahead position, etc.

DTC P0122, P0123 APP SENSORPFP:18002
DescriptionEBS011Z3
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 ModeEBS011Z4
Specification data are reference values.
*: These signals are converted by ECM internally. Thus, these differ from ECM terminals voltage.
On Board Diagnosis LogicEBS011Z6
The 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-1575, "
DTC P0642, P0643 SENSOR POWER SUPPLY" .
DTC Confirmation ProcedureEBS011Z7
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-1459, "
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.
