2015 Hyundai Sonata Temperature Sensor Location

There are two temperature sensors in a 2015 Hyundai Sonata: the engine coolant temperature sensor (ECT) and the intake air temperature sensor (IAT).

  • The ECT is located in the cylinder head, near the thermostat.
  • The IAT is located in the intake manifold, near the throttle body.

The ECT measures the temperature of the coolant in the engine and sends this information to the engine control module (ECM). The ECM uses this information to control the cooling system and to prevent the engine from overheating.

The IAT measures the temperature of the air entering the engine and sends this information to the ECM. The ECM uses this information to calculate the correct air-fuel mixture.

If either of the sensors fails, the ECM will not be able to measure the temperature of the coolant or air accurately. This can cause the engine to overheat or run inefficiently.

To replace the ECT on a 2015 Hyundai Sonata, you will need to remove the thermostat housing. This relatively complex procedure should only be performed by a qualified mechanic.

To replace the IAT on a 2015 Hyundai Sonata, you will need to remove the intake manifold. This relatively complex procedure should only be performed by a qualified mechanic.

Here are some of the signs that your temperature sensor may be failing:

  • Engine overheating
  • Engine running rough
  • Check engine light

If you are experiencing any of these problems, it is important to have your temperature sensor checked by a qualified mechanic.

Here are some tips to prevent your temperature sensor from failing:

  • Keep your coolant clean and changed regularly.
  • Do not overwork the engine.
  • Do not use engine cleaners or other harsh chemicals.
