Intake air temperature sensor location

Proper functioning of you car's air intake temperature sensor can help you avoid costly repairs to your engine and other components. Sensors are simple to test at home to ensure they are working correctly. Understand the purpose of the air intake temperature sensor.

The sensor keeps tabs on the temperature of the air circulating through the exhaust system. It is located in the air cleaner housing or duct and helps the car's computer regulate the exhaust-gas recirculation. Know when to test the sensor. The "check engine" or "service engine" light will come on as is your first indicator that something is wrong.

At this point, it could be an actual problem or a malfunctioning sensor. Remove the air intake temperature sensor after first removing the air intake housing. Let the engine cool before doing this, as you can be severely burned. Allow the sensor to cool before further testing. You will need a hair drier and ohmmeter for the testing portion of this process. Test the MAT's resistance when it is cold, by holding the probe on the ohmmeter.

Note what it registers. Then warm it up with the hair drier and test it again.

This connector is located on your air intake track as well. The location of the IAT is under the air intake manifold, the big black plastic with tubes going through it coming from the intake to the engine.

It could also be on the throttle body area. It is not the HFM after the air box which measures how may air flow is going to your engine. The IAT sensor Intake Air Temperature will usually be located on the intake hose between the filter box and the throttle body, or possibly in the filter box itself.

The IAT sensor then varies its internal resistance according to air temperature and sends a return signal back to the PCM. The PCM then uses this formation to determine fuel injector control and other outputs. A bad IAT sensor can cause all kinds of drivability problems including a rough idle, surging, stalling, and poor fuel economy.

To replace this part, you can follow the step-by-step guide below. In order to safely and efficiently replace your IAT sensor, you will need a couple of basic tools. Step 1: Locate the sensor. The IAT sensor is usually located in the air intake boot, but it may also be located in the air cleaner housing or intake manifold. Step 2: Disconnect the negative battery cable.

Safety glasses Step 1: Locate the sensor.But what does this IAT sensor actually do? WheelZine answers this question, along with telling you about the location, working, and problems of an IAT 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. This is a resistance-based sensor, which correlates the temperature of the incoming air with the magnitude of resistance, and relays this information to the car computer.

The car ECU then decides the rate at which sparking and fuel injection takes place in the engine, to get the most out of it. This helps the engine start well on a cold day, and maintains fuel economy in warm weather.

Would you like to write for us? Well, we're looking for good writers who want to spread the word. Get in touch with us and we'll talk Generally, there are three IAT sensors in a vehicle. One is used for measuring the temperature of the air entering the engine; another is used for the climate control system of the vehicle; and the third measures the ambient air temperature, i.

When the IAT sensor gets damaged, this is indicated by a variety of driveability symptoms, such as poor idling, backfiring, and unexplained surging. Since the sensor is in a solid state, no adjustments can be made to it, but it can be cleaned, or if necessary, be replaced to solve the issue. The purpose, location, working, and problems of the IAT sensor are explained here. The IAT sensor measures the temperature of air that enters the engine. This helps the Electronic Control Unit ECU of the vehicle to modify the air-fuel ratio that is injected into the combustion chamber of the engine, for its proper functioning.

This is because, the change in temperature of the air changes its density, affecting the concentration of oxygen molecules per square inch. Cold air is denser than warmer air. Thus, cold air requires more fuel to be injected into the combustion chamber to maintain the air-fuel ratio. This information is then used by the ECU to modify the rate of fuel and spark delivery.

An IAT sensor is also used by automatic climate control systems in vehicles. One sensor is used to monitor the temperature of air inside the passenger compartment, while another measures the outside air temperature.

A standalone IAT sensor is located between the air intake box and the throttle body in the air intake passage of most vehicles. The sensor may be threaded onto the inlet manifold, in which case, it is called a Manifold Air Temperature MAT sensor. This can be identified by the presence of four pins, as the MAP sensor requires only three.

The fourth pin is shared by the IAT sensor to complete its earth connection. The IAT sensor is a thermistor, which is a type of resistor that changes its resistance value with the change in temperature.The intake air temperature IAT sensor on a Dodge Ram is used by the engine computer to measure the ambient temperature of the intake air.

The computer uses this measurement to calculate the correct amount of ignition timing. When this sensor fails, it provides the computer with inaccurate temperature information, causing a number of symptoms such as lack of power, engine sputtering and rough idle. This sensor is located inside the number two intake runner.

Follow the air-intake tube from the air filter until it meets the intake manifold. Look on top left side of the intake manifold. The second intake runner begins 3 inches from the front left side of the intake manifold. The IAT sensor is located inside the number two intake runner and is a two-wire sensor.

Step 3 Follow the air-intake tube from the air filter until it meets the intake manifold. About the Author This article was written by the It Still Works team, copy edited and fact checked through a multi-point auditing system, in efforts to ensure our readers only receive the best information.The air intake temperature sensor, also known as an intake air temperature IAT sensor, air charge temperature ACT sensor, or manifold air temperature MAT sensor, measures the temperature of the outside air entering into the engine.

The colder the air is, the denser it is. The computer uses this information to adjust fuel injection and achieve the correct air to fuel ratio. Depending on your vehicle, the sensor may be mounted into the air intake box, the intake hose, or the intake manifold.

The end of it will be exposed to the air headed towards the engines combustion chamber. The sensor receives a voltage from the computer.

The output voltage is changed by a thermistor, a resistor whose resistance changes with the temperature. The computer uses that output voltage to determine the air temperature. The air intake temperature sensor can be damaged, over time, by heat or get coated with fine dirt or carbon deposits. That will make the sensor give less accurate readings to the computer.

That can make the engine run too lean or too rich, which can lead to a rough idle, knocking, misfires, or reduced gas mileage. An intake temperature sensor that reads too warm might also make it harder to start the engine in cold weather, since the engine needs more gas than normal to start in the cold.

The computer might recognize that the sensor is giving faulty readings and cause the check engine light to come on.

A diagnostic scan tool will show a code between P and P or between P and P, as shown below. Often, though, when the check engine light has come on the IAT sensor has already been faulty for some time.

Removing the intake air temperature sensor is a fairly easy task. If the sensor is located on the intake manifold, you may have to remove the intake hose or other nearby parts.

Reverse the above steps to install the new air charge temperature sensor. Air charge temperature sensors are vital to the proper operation of any automobile.
