DTC DETECTION LOGIC
NOTE:
If DTC P0222 or P0223 is displayed with DTC P0643, first perform the trouble diagnosis for DTC P0643.
Refer to EC-353, "DTC Logic".
DTC No. | CONSULT screen terms (Trouble diagnosis content) | DTC detecting condition | Possible cause |
P0222 | TP SEN 1/CIRC-B1 (Throttle/Pedal position sensor/switch “B” circuit low) | An excessively low voltage from the TP sensor 1 is sent to ECM. |
|
P0223 | TP SEN 1/CIRC-B1 (Throttle/Pedal position sensor/switch “B” circuit high) | An excessively high voltage from the TP sensor 1 is sent to ECM. |
DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 8 V at idle.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE
Is 1st trip DTC detected? YES >> Proceed to EC-266, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK THROTTLE POSITION SENSOR 1 POWER SUPPLY
Is the inspection result normal? YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK THROTTLE POSITION SENSOR 1 POWER SUPPLY CIRCUIT
Is the inspection result normal? YES >> Perform the trouble diagnosis for power supply circuit.
NO >> Repair or replace error-detected parts.
3.CHECK THROTTLE POSITION SENSOR 1 GROUND CIRCUIT
Is the inspection result normal? YES >> GO TO 4.
NO >> Repair or replace error-detected parts.
4.CHECK THROTTLE POSITION SENSOR 1 INPUT SIGNAL CIRCUIT
Is the inspection result normal? YES >> GO TO 5.
NO >> Repair or replace error-detected parts.
5.CHECK THROTTLE POSITION SENSOR
Check throttle position sensor. Refer to EC-268, "Component Inspection (TP Sensor)".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Replace electric throttle control actuator. Refer to EM-27, "Removal and Installation".
Component Inspection (TP Sensor)
1.CHECK THROTTLE POSITION SENSOR
Is the inspection result normal? YES >> INSPECTION END
NO >> Replace electric throttle control actuator. Refer to EM-27, "Removal and Installation".
