P1675 ENGINE COOLANT TEMPERATURE
DTC Description
INFOID:0000000010935873
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
Stop closed-loop control
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-1170, "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
EC-1170, "Diagnosis Procedure"
NO
>> GO TO 3.
3.
PERFORM COMPONENT FUNCTION CHECK-3
1.
Start engine and let it idle.
DTC No.
