P0225 APP SENSOR

P0225 APP SENSOR

Description

INFOID:0000000001162604

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.

DTC Logic

INFOID:0000000001162605

DTC DETECTION LOGIC

NOTE:
• If DTC P0225 is displayed with DTC P0641, first perform trouble diagnosis for DTC P0641. Refer to

EC-1180, "DTC Logic"

.

• If DTC P0225 is displayed with DTC P0651, first perform trouble diagnosis for DTC P0651. Refer to

EC-1182, "DTC Logic"

.

• If DTC P2120 is present at the same time, check that the APP sensor connector is connected cor-

rectly.

• Conditions for applying the diagnostic procedure to the stored DTCs: 
- The DTC is declared present after a series of full load/no load action on the accelerator.
• If the DTC is present:
Malfunction indicator (Red) lights up.

Diagnosis Procedure

INFOID:0000000001162606

1.

CHECK GROUND CONNECTIONS

1.

Turn ignition switch OFF.

2.

 Check ground connection E15. Refer to Ground inspection in 

GI-58, "Circuit Inspection"

.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair or replace ground connection.

2.

CHECK ACCELERATOR PEDAL POSITION SENSOR POWER SUPPLY CIRCUIT

1.

Disconnect accelerator pedal position sensor harness connector.

2.

Turn ignition switch ON.

3.

Check the voltage between accelerator pedal position sensor connector and ground.
