P0125 ECT SENSOR

P0125 ECT SENSOR

DTC Description

INFOID:0000000011277970

DTC DETECTION LOGIC

POSSIBLE CAUSE

• Harness or connectors (High resistance in the circuit)

• Engine coolant temperature sensor

• Thermostat

FAIL-SAFE

Not applicable

DTC CONFIRMATION PROCEDURE

1.

CHECK DTC PRIORITY

If DTC P0125 is displayed with DTC P0116 or P0117, first perform the trouble diagnosis for DTC P0116 or

P0117.
Is applicable DTC detected?

YES

>> Perform diagnosis of applicable. Refer to 

EC-96, "DTC Index"

.

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.

>> GO TO 3.

3.

CHECK ENGINE COOLANT TEMPERATURE SENSOR FUNCTION

With CONSULT

1. Turn ignition switch ON.

2. Select “DATA MONITOR” mode of “ENGINE” using CONSULT.

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

°C (50°F).

With GST

Follow the procedure “With CONSULT” above.
Is it above 5

°C (41°F)?

YES

>> INSPECTION END

NO

>> GO TO 4.

4.

PERFORM DTC CONFIRMATION PROCEDURE

With CONSULT

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

2. Check 1st tip DTC.

If “COOLAN TEMP/S” indication increases to more than 10

°C (50°F) within 65 minutes, stop engine

because the test result will be OK.

CAUTION:

Be careful not to overheat engine.

With GST

Follow the procedure “With CONSULT” above.

DTC No.
