Details On DTCs

DESCRIPTION

ECT sensor circuit range/performance problem
DETECTION CONDITION
Determination conditions
•  During the 5 min after the engine is started, the engine coolant temperature does not increase above 6 °C {11 °F} (Type A VIN)/0.7 °C {1 °F} (Type B VIN/Type C VIN).
Preconditions
•  Before starting the engine, leave the vehicle with the engine turned off for 6 hours or more.
•  The following DTCs are not detected:
?  ECT sensor: P0117:00, P0118:00
Drive cycle
•  1
Self test type
•  CMDTC self test
Sensor used
•  ECT sensor
FAIL-SAFE FUNCTION
•  Not applicable
VEHICLE STATUS WHEN DTCs ARE OUTPUT
•  The check engine light may be illuminated depending on the condition.
POSSIBLE CAUSE
•  ECT sensor connector or terminals malfunction
•  PCM connector or terminals malfunction
•  ECT sensor loose
•  ECT sensor malfunction
•  Poor assembly of engine coolant hose (engine coolant passage malfunction)
•  Poor engine coolant, leakage, or freezing
•  Use of unspecified engine coolant
•  Thermostat malfunction
•  PCM malfunction

System Wiring Diagram

•  Not applicable

Function Explanation (DTC Detection Outline)

•  If the engine coolant temperature detected by the ECT sensor is not rising 6 °C {11 °F} (Type A VIN)/0.7 °C {1 °F} (Type B VIN/Type C VIN) or more during a 5 min period after the engine is started, the PCM determines an ECT sensor malfunction and stores a DTC.

Repeatability Verification Procedure

1.  Start the engine and leave it idling for 10 s.
2.  Switch the ignition off.
3.  Leave the vehicle for 6 hours or more.
4.  Start the engine and leave it idling for 6 min.

STEP

INSPECTION

RESULTS

ACTION
1
PURPOSE: VERIFY RELATED SERVICE INFORMATION AVAILABILITY
•  Verify related Service Information availability.
•  Is any related Service Information available?
Yes
Perform repair or diagnosis according to the available Service Information.
•  If the vehicle is not repaired, go to the next step.
No
Go to the next step.
2
PURPOSE: RECORD VEHICLE STATUS AT TIME OF DTC DETECTION TO UTILIZE WITH REPEATABILITY VERIFICATION
Note
•  Recording can be facilitated using the screen capture function of the PC.
•  Record the FREEZE FRAME DATA/snapshot data on the repair order.
—
Go to the next step.
3
PURPOSE: VERIFY CONNECTOR CONNECTIONS
•  Start the engine.
•  Access the ECT PID using the M-MDS.
•  Does the PID value fluctuate when the PCM and ECT sensor connectors are shaken?
Yes
Repair or replace the applicable connector parts.
Go to the troubleshooting procedure to perform the procedure from Step 7.
No
Go to the next step.
4
PURPOSE: VERIFY ECT SENSOR INPUT SIGNAL
•  Access the ECT PID using the M-MDS.
•  Is the PID value within specification?
Yes
Go to the troubleshooting procedure to perform the procedure from Step 3.
No
Go to the troubleshooting procedure to perform the procedure from Step 1.

Troubleshooting Diagnostic Procedure

Intention of troubleshooting procedure
•  Step 1—2
?  Perform an ECT sensor-related inspection.
•  Step 3—5
?  Perform an engine coolant-related inspection.
•  Step 6
?  Perform a unit inspection of the thermostat.
•  Step 7—8
?  Verify that the primary malfunction is resolved and there are no other malfunctions.

STEP

INSPECTION

RESULTS

ACTION
1
PURPOSE: INSPECT INSTALLATION OF ECT SENSOR
•  Inspect installation of ECT sensor.
•  Is the ECT sensor installed securely?
Yes
Go to the next step.
No
Retighten the ECT sensor, then go to Step 7.
(See ENGINE COOLANT TEMPERATURE (ECT) SENSOR REMOVAL/INSTALLATION [SKYACTIV-G 2.5T].)
2
PURPOSE: DETERMINE INTEGRITY OF ECT SENSOR
•  Inspect the ECT sensor.
•  Is there any malfunction?
Yes
Replace the ECT sensor, then go to Step 7.
(See ENGINE COOLANT TEMPERATURE (ECT) SENSOR REMOVAL/INSTALLATION [SKYACTIV-G 2.5T].)
No
Go to the next step.
3
PURPOSE: VERIFY IF MALFUNCTION CAUSED BY POOR ENGINE COOLANT PASSAGE ASSEMBLY
•  Verify the connection condition of the engine coolant passage (such as hoses).
•  Is there any malfunction?
Yes
Reconnect the engine coolant passage correctly.
Replace the engine coolant, then go to Step 7.
(See ENGINE COOLANT REPLACEMENT [SKYACTIV-G 2.5T].)
No
Go to the next step.
4
PURPOSE: VERIFY IF MALFUNCTION RELATED TO ENGINE COOLANT AFFECTS DIAGNOSTIC RESULTS
•  Inspect the following:
?  Is the system filled with the specified engine coolant?
?  Is there the possibility of freezing (low engine coolant concentration)?
?  Has foreign matter penetrated the engine coolant?
•  Are all items normal?
Yes
Go to the next step.
No
Replace the engine coolant, then go to Step 7. (Advise the customer to use specified engine coolant used.)
(See ENGINE COOLANT REPLACEMENT [SKYACTIV-G 2.5T].)
5
PURPOSE: VERIFY IF MALFUNCTION RELATED TO ENGINE COOLANT LEAKAGE FROM ENGINE COOLANT PASSAGE AFFECTS DIAGNOSTIC RESULTS
•  Perform the “ENGINE COOLANT LEAKAGE INSPECTION”.
•  Is there engine coolant leaking from the engine coolant passage?
Yes
Repair or replace the malfunctioning location and refill the system with engine coolant.
(See ENGINE COOLANT REPLACEMENT [SKYACTIV-G 2.5T].)
Go to Step 7.
No
Go to the next step.
6
PURPOSE: DETERMINE INTEGRITY OF THERMOSTAT
•  Inspect the thermostat.
•  Is there any malfunction?
Yes
Replace the thermostat, then go to the next step.
(See THERMOSTAT REMOVAL/INSTALLATION [SKYACTIV-G 2.5T].)
No
Go to the next step.
7
PURPOSE: VERIFICATION OF VEHICLE REPAIR COMPLETION
•  Always reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Implement the repeatability verification procedure.
•  Perform the DTC Reading Procedure.
•  Is the same DTC present?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the PCM.
Go to the next step.
No
Go to the next step.
8
PURPOSE: VERIFY IF THERE IS ANY OTHER MALFUNCTION
•  Is any other DTC or pending code stored?
Yes
Go to the applicable DTC inspection.
