DTC DETECTION LOGIC

NOTE:

• If DTC P0125 is displayed with P0116, first perform the trouble diagnosis for DTC P0116. Refer to 

EC-

858, "DTC Logic"

.

• If DTC P0125 is displayed with P0117 or P0118, first perform the trouble diagnosis for DTC P0117,

P0118. Refer to 

EC-860, "DTC Logic"

.

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following before conduct-

ing 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.

>> GO TO 2.

2.

CHECK ENGINE COOLANT TEMPERATURE SENSOR 1 FUNCTION

With CONSULT

1. Turn ignition switch ON.

2. Select “DATA MONITOR” mode with CONSULT.

3. Check that “COOLANT TEMP/S” is above 10

°C (50°F).

Is the temperature above 10

°C (50°F)?

YES

>> INSPECTION END

NO

>> GO TO 3.

3.

PERFORM DTC CONFIRMATION PROCEDURE

With CONSULT

1. Start engine and run it for 65 minutes at idle speed.

If “COOLANT TEMP/S” increases to more than 

−7°C (19.4°F) within 65 minutes, stop engine

because the test result will be OK.

CAUTION:

Never overheat engine.

2. Check 1st trip DTC.
Is 1st trip DTC detected?

YES

>>

EC-867, "Diagnosis Procedure"

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000012198378

1.

CHECK ENGINE COOLANT TEMPERATURE SENSOR 1

Check engine coolant temperature sensor 1. Refer to 

EC-868, "Component Inspection"

.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Replace engine coolant temperature sensor 1.

DTC No.

ECT SENSOR
(Insufficient coolant tempera-
ture for closed loop fuel control)

• Voltage sent to ECM from the sensor is not 

practical, even when some time has passed 
after starting the engine.

• Engine coolant temperature is insufficient for 

closed loop fuel control.

• Harness or connectors

(High resistance in the circuit)

• Engine coolant temperature sensor

2.

CHECK MULTI-WAY CONTROL VALVE OPERATION

When the engine is cold [lower than 64

°C (147°F)] condition, grasp lower radiator hose and confirm that the

engine coolant does not flow.
Is the inspection result normal?

YES

>> Check intermittent incident. Refer to 

GI-45, "Intermittent Incident"

.

NO

>> Repair or replace water outlet (MCV). Refer to 

CO-54, "Exploded View"

.
