P0217 ENGINE OVER TEMPERATURE

DTC Logic

INFOID:0000000010379082

DTC DETECTION LOGIC

If the cooling fan or another 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.
NOTE:
If DTC P0217 is display with DTC P0115 or P0597, first perform the trouble diagnosis for DTC P0115 or
P0597. Refer to 

ECH-71, "DTC Index"

.

CAUTION:

When a malfunction is indicated, be sure to replace the coolant. Refer to 

CO-11, "Draining"

 and 

CO-11,

"Refilling"

. Also, replace the engine oil. Refer to 

LU-9, "Draining"

 and 

LU-9, "Refilling"

.

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. Refer to 

MA-61, "Engine Coolant Mixture Ratio"

.

2.

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

DTC CONFIRMATION PROCEDURE

1.

PERFORM COMPONENT FUNCTION CHECK

Perform component function check. Refer to 

ECH-191, "Component Function Check"

.

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 inspection result normal?

YES

>> INSPECTION END

NO

>> Go to 

ECH-192, "Diagnosis Procedure"

.

Component Function Check

INFOID:0000000010379083

1.

PERFORM COMPONENT FUNCTION CHECK-1

WARNING:

Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pres-
sure 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.

DTC No.

P0217 ENGINE OVER TEMPERATURE

Check the coolant level in the reservoir tank and radiator.
Allow engine to cool before checking coolant level.
Is the coolant level in the reservoir tank and/or radiator below the
proper range?

YES

>> Proceed to 

ECH-192, "Diagnosis Procedure"

.

NO

>> GO TO 2

2.

PERFORM COMPONENT FUNCTION CHECK-2

Confirm whether customer filled the coolant or not.

Did customer fill the coolant?

YES

>> Proceed to 

ECH-192, "Diagnosis Procedure"

.

NO

>> GO TO 3.

3.

PERFORM COMPONENT FUNCTION CHECK-3

Without CONSULT

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 

ECH-192, "Diagnosis Procedure"

.

4.

PERFORM COMPONENT FUNCTION CHECK-4

Without CONSULT

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

>> INSPECTION END

NO

>> Proceed to 

ECH-192, "Diagnosis Procedure"
