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, "DTC Logic".
DTC No. | Trouble diagnosis name | DTC detecting condition | Possible cause |
P0222 | Throttle position sensor 1 circuit low input | An excessively low voltage from the TP sensor 1 is sent to ECM. |
|
P0223 | Throttle position sensor 1 circuit high input | 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 turn ignition switch OFF and wait at least 10 seconds before conducting the next test.
TESTING CONDITION: Before performing the following procedure, confirm that battery voltage is more than 10 V at idle.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE
Is DTC detected?
YES >> Go to EC, "Diagnosis Procedure".
NO >> INSPECTION END
1.CHECK GROUND CONNECTION
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair or replace ground connection.
2.CHECK THROTTLE POSITION SENSOR 1 POWER SUPPLY CIRCUIT
Is the inspection result normal?
YES >> GO TO 3.
NO >> Repair open circuit or short to ground or short to power in harness or connectors.
3.CHECK THROTTLE POSITION SENSOR 1 GROUND CIRCUIT FOR OPEN AND SHORT
4. Also check harness for short to ground and short to power.
Is the inspection result normal?
YES >> GO TO 4.
NO >> Repair open circuit or short to ground or short to power in harness or connectors.
4.CHECK THROTTLE POSITION SENSOR 1 INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1. Check the continuity between electric
throttle control actuator harness connector and ECM harness connector.
2. Also check harness for short to ground and short to power.
Is the inspection result normal?
YES >> GO TO 5.
NO >> Repair open circuit or short to ground or short to power in harness or connectors.
5.CHECK THROTTLE POSITION SENSOR
Refer to EC, "Component Inspection".
Is the inspection result normal?
YES >> GO TO 7.
NO >> GO TO 6.
6.REPLACE ELECTRIC THROTTLE CONTROL ACTUATOR
Replace electric throttle control actuator. Refer to EM, "Removal and Installation".
>> INSPECTION END
7.CHECK INTERMITTENT INCIDENT
Refer to GI, "Intermittent Incident".
>> INSPECTION END
Component Inspection
1.CHECK THROTTLE POSITION SENSOR
Is the inspection result normal?
YES >> INSPECTION END
NO >> GO TO 2.
2.REPLACE ELECTRIC THROTTLE CONTROL ACTUATOR
Replace electric throttle control actuator. Refer to EM, "Removal and Installation".
