1. Turn ignition switch OFF.

2. Disconnect ECM harness connector.

3. Check the continuity between ECT sensor harness connector and ECM harness connector.

4. Also check harness for short to ground.
Is the inspection result normal?

YES

>> Perform the trouble diagnosis for power supply circuit.

NO

>> Repair or replace error-detected parts.

3.

CHECK ENGINE COOLANT TEMPERATURE SENSOR GROUND CIRCUIT

1. Turn ignition switch OFF.

2. Disconnect ECM harness connector.

3. Check the continuity between ECT sensor harness connector and ECM harness connector.

4. Also check harness for short to ground to power.
Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Repair or replace error-detected parts.

4.

CHECK ENGINE COOLANT TEMPERATURE SENSOR

Check the engine coolant temperature sensor. Refer to 

EC-215, "Component Inspection"

.

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> Replace engine coolant temperature sensor. Refer to 

CO-23, "Exploded View"

DTC Description

INFOID:0000000011277967

DTC DETECTION LOGIC

POSSIBLE CAUSE

• Harness or connectors (TP sensor 2 circuit is open or shorted.)

• Electric throttle control actuator (TP sensor 2)

FAIL-SAFE

• The ECM controls the electric throttle control actuator in regulating the throttle opening in order for the idle

position to be within +10 degrees.

• The ECM regulates the opening speed of the throttle valve to be slower than the normal condition. So, the

acceleration will be poor.

DTC CONFIRMATION PROCEDURE

1.

CHECK DTC PRIORITY

If DTC P0122 or P0123 is displayed with DTC P0643, first perform the trouble diagnosis for DTC P0643.
Is applicable DTC detected?

YES

>> Perform diagnosis of applicable. Refer to 

EC-382, "DTC Description"

.

NO

>> GO TO 2.

2.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure

before conducting the next test.

1. Turn ignition switch OFF and wait at least 10 seconds.

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 3.

3.

PERFORM DTC CONFIRMATION PROCEDURE

1. Start engine and let it idle for 1 second.

2. Check DTC.
Is DTC detected?

YES

>> Proceed to 

EC-219, "Diagnosis Procedure"

.

NO
