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
.
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.
