DTC P0122, P0123 APP SENSOR
DTC P0122, P0123 APP SENSOR
PFP:18002
Description
EBS013AE
The accelerator pedal position sensor is installed on the upper end
of the accelerator pedal assembly. The ECM uses the signal to
determine the amount of fuel to be injected.
CONSULT-II Reference Value in Data Monitor Mode
EBS013AF
Specification data are reference values.
*: This signal is converted by ECM internally. Thus, it differs from ECM terminal voltage.
ECM Terminals and Reference Value
EBS013AG
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.

On Board Diagnosis Logic
EBS013AH
These self-diagnoses have the one trip detection logic.
The MI will not light up for these self-diagnoses.
DTC Confirmation Procedure
EBS013AI
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-1053, "Diagnostic Procedure"
.
WITH GST
Follow the procedure “WITH CONSULT-II” above.

connector.
2.
Turn ignition switch ON.
3.
Check voltage between APP sensor terminal 2 and ground with
CONSULT-II or tester.
OK or NG
OK
>> GO TO 3.
NG
>> Repair open circuit or short to ground or short to power
in harness or connectors.
3.
CHECK APP SENSOR 1 GROUND CIRCUIT FOR OPEN AND SHORT
1.
Turn ignition switch OFF.
2.
Disconnect ECM harness connector.
3.
Check harness continuity between APP sensor terminal 4 and ECM terminal 84.
Refer to Wiring Diagram.
4.
