|
• Not applicable
|
|
|
Vehicle status when DTCs are output
|
• Not applicable
|
|
|
Possible cause
|
• ECT sensor No.1 connector or terminals malfunction
• PCM connector or terminals malfunction
• ECT sensor No.1 incorrect installation
• ECT sensor No.1 malfunction
• Poor assembly of engine coolant hose (engine coolant passage malfunction)
• Poor engine coolant, leakage, or freezing

|
System Wiring Diagram
• Not applicable
Function Explanation (DTC Detection Outline)
• If the engine coolant temperature detected by the ECT sensor No.1 is not rising 3 °C {5 °F} or more during a 7 min period after the engine is started, the PCM determines an ECT sensor No.1 malfunction and stores a DTC.

1
|
PURPOSE: VERIFY IF ECT SENSOR No.1 IS INSTALLED CORRECTLY
• Verify the ECT sensor No.1 installation condition. (See ENGINE COOLANT TEMPERATURE (ECT) SENSOR REMOVAL/INSTALLATION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].) (See ENGINE COOLANT TEMPERATURE (ECT) SENSOR REMOVAL/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
• Is the installation condition normal?
|
Yes
|
Go to the next step.
|
|
No
|
Correctly install the ECT sensor No.1 and perform the repair completion verification.
|
||
|
2
|
PURPOSE: INSPECT ECT SENSOR No.1 FOR MALFUNCTION
• Inspect the applicable part. (See ENGINE COOLANT TEMPERATURE (ECT) SENSOR INSPECTION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].) (See ENGINE COOLANT TEMPERATURE (ECT) SENSOR INSPECTION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
• Is the part normal?
|
Yes
|
Go to the next step.
|
|
No
|
Repair or replace the malfunctioning location and perform the repair completion verification.
|
||
|
3
|
PURPOSE: VERIFY IF MALFUNCTION CAUSED BY POOR ENGINE COOLANT PASSAGE ASSEMBLY
• Verify the connection condition of the engine coolant passage (such as hoses). (See COOLING SYSTEM LOCATION INDEX [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].) (See COOLING SYSTEM LOCATION INDEX [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)

Repair completion verification 1
|
PURPOSE: VERIFY THAT VEHICLE IS REPAIRED
• Install/connect the part removed/disconnected during the troubleshooting procedure.
• Clear the DTC recorded in the memory. (See CLEARING DTC.)

• Is the same Pending DTC present?
|
Yes
|
Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error.
If the CAN communication is normal, perform the diagnosis from Step 1.
• If the malfunction recurs, replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].) (See PCM REMOVAL/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
