How does the IAT sensor work on a car?
How does the IAT sensor work on a car?
The IAT sensor (a sensor in the area of the MAF sensor) measures the temperature of the incoming air and transmits a corresponding electrical signal. Another temperature sensor (the ECT sensor) inserted in the engine coolant tells if the engine is cold or warmed up.
What is the purpose of an intake air temperature sensor?
This tricks the ECU into thinking that the incoming air is cooler than it actually is, making it pump more fuel into the engine. The result is enhanced engine power. The Intake Air Temperature sensor is commonly integrated with the Mass Air Flow (MAF) sensor, and is found in the air intake passage below the hood.
What does the code p0112 mean on the IAT sensor?
The P0112 code indicates that the IAT sensor is operating at a low voltage and reports a temperature of about 300 °F (149 °C). The P0113 code is caused by a high circuit voltage and means that the IAT sensor reports a temperature of about -38 °F (-39 °C). What is an Intake Air Temperature Sensor?
How does the MAF sensor work in a car?
The MAF sensor (a potentiometer) senses the quantity of airflow in the engine’s air induction system and generates a voltage signal that varies with the amount of air drawn into the engine. The IAT sensor (a sensor in the area of the MAF sensor) measures the temperature of the incoming air and transmits a corresponding electrical signal.

Where is the Idle Air Control Sensor located?
IAC – Idle Air Control Sensor – FreeAutoMechanic The Idle Air Control (IAC) valve controls the engine idle speed and dashpot functions. The valve is located on the side of the throttle body. IAC – Idle Air Control Sensor Idle Air Control (IAC) OPERATION The Idle Air Control (IAC) valve controls the engine idle speed and dashpot functions.
How can I change the resistance of the IAC valve?
Disengage the wiring harness connector from the IAC valve . Using an ohmmeter, measure the resistance between the terminals of the valve. NOTE: Due to the diode in the solenoid, place the ohmmeter positive lead on the VPWRterminal and the negative lead on the ISC terminal. If the resistance is not 7–13 ohms, replace the IAC valve.
