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.

Possible cause

P0122

Accelerator pedal position
sensor 1 circuit low input

An excessively low voltage from the APP sensor
1 is sent to ECM.

●

Harness or connectors
(The APP sensor 1 circuit is open or
shorted.)

●

Accelerator pedal position sensor
(Accelerator pedal position sensor 1)

P0123

Accelerator pedal position
sensor 1 circuit high input

An excessively high voltage from the APP sensor
1 is sent to ECM.

Diagnostic Procedure

EBS013AK

1.

CHECK GROUND CONNECTIONS

1.

Turn ignition switch OFF.

2.

Loosen and retighten body ground screw. Refer to

EC-1010,

"Ground Inspection"

.

OK or NG

OK

>> GO TO 2.

NG

>> Repair or replace ground connection.

2.

CHECK APP SENSOR 1 POWER SUPPLY CIRCUIT

1.

Disconnect accelerator pedal position (APP) sensor harness
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.

Also check harness for short to ground and short to power.
