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 DETECTION LOGIC
NOTE:
• If DTC P0225 is displayed with DTC P0641, first perform trouble diagnosis for DTC P0641. Refer to
.
• If DTC P0225 is displayed with DTC P0651, first perform trouble diagnosis for DTC P0651. Refer to
.
• 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
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.
