NTK EF0018 coolant temperature sensor for the 2008-2019 Hyundai Sonata 4-cylinder 2.4L, the 2011-2019 Sonata 4-cylinder 2.0L and other vehicles reads the temperature of the engine coolant and sends an analog signal to the ECM. That signal supports a proper air/fuel ratio and the operation of the cooling fan and temperature gauge.
- Brass housing with thermal conductive grease for faster sensor response time
- Thermal conductive grease carries heat to the thermistor for accurate temperature readings
- Thermistor placement inside the housing is set for proper output
Quick facts
- Part: NTK EF0018 coolant temperature sensor
- Also called: engine coolant temperature sensor
- Fits: the 2008-2019 Hyundai Sonata 4-cylinder 2.4L, the 2011-2019 Sonata 4-cylinder 2.0L and other vehicles
- Condition: New
A check engine light, a temperature gauge that reads erratically or not at all, or a cooling fan that runs erratically or not at all can mean the sensor has failed. Those signs alone do not prove it, because a wiring fault is another common cause of the same complaints.
Fits
This sensor is a direct-fit replacement for the 2008-2019 Hyundai Sonata 4-cylinder 2.4L and the 2011-2019 Sonata 4-cylinder 2.0L. It also works as a coolant temperature sensor for the 2009-2020 Kia Optima 4-cylinder 2.4L, the 2011-2020 Optima 4-cylinder 2.0L and the 2019 Optima 4-cylinder 1.6L, and it fits the 2012-2020 Kia Sorento 4-cylinder 2.4L, the 2016-2018 Sorento 4-cylinder 2.0L and the 2019-2020 Sorento V6 3.3L. If your car is not named here, look up its year, model and engine in the "Vehicles it fits" section before you order.

Frequently Asked Questions
Is this the right coolant temperature sensor for the 2008-2019 Hyundai Sonata 4-cylinder 2.4L?
Yes. NTK EF0018 fits the 2008-2019 Hyundai Sonata 4-cylinder 2.4L and the 2011-2019 Sonata 4-cylinder 2.0L. For another car, look it up in the "Vehicles it fits" section.
Is EF0018 the coolant temperature sensor for the 2019-2020 Kia Sorento V6 3.3L?
Yes. NTK EF0018 fits the 2019-2020 Kia Sorento V6 3.3L, and that engine takes one sensor.
What is inside the housing of this NTK coolant temperature sensor?
Thermal conductive grease sits inside a brass housing. It increases sensor response time and carries temperature accurately to the thermistor.
Where is the engine coolant temperature sensor usually located?
It may be located on the cylinder head, engine block, thermostat housing or intake manifold.
Does NTK EF0018 come with an o-ring or mounting clips?
Thread sealant or an o-ring is pre-installed where applicable, and mounting clips are included where applicable. The listing is one sensor.
