Temperature sensor is a thermistor, meaning its electrical resistance changes Sensor will also have an air temperature sensor built into it. (MAF) sensors to check the air volume entering the engine, the MAP Will be exposed to air gaining access to the engine. Temperature sensor is mounted in the intake manifold in such a way that the tip How Does The Air Temperature Sensor Works? Manifold which is directly behind the throttle valve housing. Temperature Charge (IAT) sensor in a car is located on the bottom of the intake Where is the Air Charge Temperature Sensor Located in a Car? The PCM changes the air/fuel proportion by changing the length of time of the injector pulses.Īir Charge Temperature sensor on pre-OBD II vehicles (1995 & older). Since colder air is denser than hot air, cold air requires more fuel to maintain equal air/fuel ratio. This information is required by the engine computer to evaluate air density, for the sole purpose of balancing air/fuel mixture. The major function of the Air Charge Temperature sensor, also called Intake Air Temperature Sensor (IAT) monitors the temperature of the air gaining access to the engine. Factory diagrams are much harder to read.Last updated on November 18th, 2019 at 02:58 pm offers redrawn diagrams as well as factory diagrams. That saves a lot of time because you don’t have to refer back to the component locator or circuit locations. redraws factory wiring diagrams in color and includes the component, splice and ground locations right in their diagrams. If you’re tracking down a wiring issue, is the better choice. In most cases, their diagrams are right from the factory manuals. They include wiring diagrams and technical service bulletins.
