P0217 ENGINE OVER TEMPERATURE

DTC Description

INFOID:0000000010935695

DTC DETECTION LOGIC

If the cooling fan or other component in the cooling system malfunctions, engine coolant temperature will rise.
When the engine coolant temperature reaches an abnormally high temperature condition, a malfunction is
indicated.

CAUTION:

When a malfunction is indicated, be sure to replace the coolant. Also, replace the engine oil. 
1.

Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure to
use coolant with the proper mixture ratio.

2.

After refilling coolant, run engine to ensure that no water-flow noise is emitted.

POSSIBLE CAUSE

• Cooling fan
• Radiator hose
• Radiator
• Radiator cap
• Water pump
• Thermostat
• Engine coolant bypass valve control solenoid valve
• Engine coolant temperature sensor

FAIL-SAFE

• Cooling FAN Activated
• Controlled shutters opening (if present)
• Warning overheating lamp activated
• Opening of the engine coolant thermostat (request of ineffective opening in that case) (if present)
• Prohibit stop/start system
• EGR control cut off (if present)
• A/C compressor cut-off (if present)

DTC CONFIRMATION PROCEDURE

1.

PERFORM COMPONENT FUNCTION CHECK-1

WARNING:

Never remove the reservoir tank cap when the engine is hot. Serious burns could be caused by high
pressure fluid escaping from the radiator.
Wrap a thick cloth around cap. Carefully remove the cap by turning it a quarter turn to allow built-up
pressure to escape. Then turn the cap all the way off.
Check the coolant level in the reservoir tank and radiator.
Allow engine to cool before checking coolant level.
NOTE:
Use component function check to check the overall function of the
cooling fan. During this check, a DTC might not be confirmed.
Is the coolant level in the reservoir tank and/or radiator below the
proper range?

YES

>> Proceed to 

EC-1022, "Diagnosis Procedure"

.

NO

>> GO TO 2.

DTC No.

PERFORM COMPONENT FUNCTION CHECK-2

Confirm whether customer filled the coolant or not.
Did customer fill the coolant?

YES

>> Proceed to 

EC-1022, "Diagnosis Procedure"

.

NO

>> GO TO 3.

3.

PERFORM COMPONENT FUNCTION CHECK-3

1.

Start engine and let it idle.

2.

Turn air conditioner switch and blower fan switch ON.

3.

Make sure that cooling fan operates at low speed.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Proceed to 

EC-1022, "Diagnosis Procedure"

.

4.

PERFORM COMPONENT FUNCTION CHECK-4

1.

Turn ignition switch OFF.

2.

Turn air conditioner switch and blower fan switch OFF.

3.

Disconnect engine coolant temperature sensor harness connector.

4.

Connect 150

Ω

 resistor to engine coolant temperature sensor harness connector.

5.

Restart engine and make sure that cooling fan operates at higher speed than low speed.

Is the inspection result normal?

YES-1 >> To check malfunction symptom before repair: Refer to 

GI-44, "Intermittent Incident"

.

YES-2 >> Confirmation after repair: INSPECTION END
NO

>> Proceed to 

EC-1022, "Diagnosis Procedure"

Diagnosis Procedure

INFOID:0000000010935697

1.

CHECK COOLING FAN OPERATION

Check cooling fan operation.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair or replace malfunctioning part.

2.

CHECK COOLING SYSTEM FOR LEAK-1

Check cooling system for leak.

Is leakage detected?

YES

>> GO TO 3.

NO

>> GO TO 4.

3.

CHECK COOLING SYSTEM FOR LEAK-2

Check the following for leak.
• Hose
• Radiator
• Radiator cap
• Water pump
• Reservoir tank

>> Repair or replace malfunctioning part.

4.

CHECK RADIATOR CAP

Check radiator cap.
Is the inspection result normal?

YES

>> GO TO 5.

NO

>> Replace radiator cap.

5.
