Air Temp Sensor Resistance

Take a look at the symptoms and understand why such a problem occurs.

Air temp sensor resistance.

Allow the sensor to cool before further testing. Use a multimeter and verify the manufacturer s specifications 220 240 ohms at 70 80 f to test this sensor for proper resistance. Different names for the iat sensor. The in car temperature sensor icts is an ntc.

An iat sensor is an important component that is needed while starting up a vehicle s engine. Two types of iat sensors. The resistance of the temperature sensor changes depending on the intake air temperature. Testing the iat sensor.

The intake air temperature sensor or iat sensor has the core function of monitoring the temperature of the air that is entering the engine of your vehicle. The control unit evaluates these voltage values since they are directly related to the intake air temperature low temperatures result in high voltage values. Automotive air conditioning systems use ntc sensors to monitor air temperature. As the temperature increases the resistance is reduced which reduces the voltage at the sensor.

Temperature and resistance values of an iat sensor. A faulty sensor can decrease the life of the engine and reduce the efficiency of fuel consumption. Verify any suspicions with a visual inspection of the sensor and its connector. Let the engine cool before doing this as you can be severely burned.

Intake air temperature sensor location. This information is very useful for the engine control unit or ecu for many functions and calculations such as calculating the air density for effective ignition timing and fuel efficiency. Testing the iat sensor off the vehicle. Remove the air intake temperature sensor after first removing the air intake housing.

A checking iat sensor resistance. Never use this to test.
