2. Turn ignition switch ON.
3. Turn ignition switch OFF and wait at least 10 seconds.
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
1. Start engine and let it idle for 1 second.
2. Check DTC.
Is DTC detected? YES >> Proceed to EC-202, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK THROTTLE POSITION SENSOR 2 POWER SUPPLY
1. Turn ignition switch OFF.

3. Turn ignition switch ON.
4. Check the voltage between electric throttle control actuator harness connector and ground.
Is the inspection result normal? YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK THROTTLE POSITION SENSOR 2 GROUND CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Check the continuity between electric throttle control actuator harness connector and ECM harness connector.
4. Also check harness for short to power.
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 2 GROUND CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Check the continuity between electric throttle control actuator harness connector and ECM harness connector.
Is the inspection result normal? YES >> GO TO 4.
NO >> Repair or replace error-detected parts.
4.CHECK THROTTLE POSITION SENSOR 2 INPUT SIGNAL CIRCUIT
1. Check the continuity between electric throttle control actuator harness connector and ECM harness connector.
2. Also check harness for short to ground and to power.
Is the inspection result normal? YES >> GO TO 5.
NO >> Repair or replace error-detected parts.
5.CHECK THROTTLE POSITION SENSOR
Check the throttle position sensor. Refer to EC-203, "Component Inspection".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-42, "Intermittent Incident".
NO >> Replace electric throttle control actuator. Refer to EM-28, "Exploded View".
Component Inspection
1.CHECK THROTTLE POSITION SENSOR
1. Turn ignition switch OFF.
2. Reconnect all harness connectors disconnected.
3. Perform “ Throttle Valve Closed Position Learning”. Refer to EC-135, "Work Procedure".
4. Turn ignition switch ON.
5. Set selector lever to D (CVT) or 1st (M/T) position.
6. Check the voltage between ECM harness connector terminals as per the following conditions.
Is the inspection result normal? YES >> INSPECTION END
NO >> Replace electric throttle control actuator. Refer to EM-28, "Exploded View".
