Where is the air intake sensor?
The intake air temperature sensor (IAT) is located in the air pipe at the back of the main entrance. The intake air temperature sensor (IAT) is located at the bottom of the intake collector, directly behind the acceleration valve box.
What happens if IAT sensor is bad?
A malfunctioning IAT sensor may cause your vehicle to take longer to start on cold mornings. The faulty IAT sensor tells the car’s computer that the air in the intake is a different temperature than it actually is and may cause the vehicle to not deliver the proper fuel mixture to the engine.
What will a bad IAT sensor cause?
What does the MAF sensor on a Toyota do?
The MAF sensor’s job is to measure the amount of air entering the engine (when the engine is running) and transmit this info to your Toyota’s fuel injection computer. The computer then uses this air flow measurement, along with other sensor inputs, to inject the correct amount of fuel into the engine.
What happens when the IAT sensor goes bad on a Toyota?
When the intake air temperature (IAT) sensor on your Toyota goes bad, the check engine light (CEL) will immediately illuminate to let you know that there’s a problem and that a diagnostic trouble code has set to indicate a problem. Here are some of the specific symptoms you’ll see/have:
How does the intake air temperature sensor work?
The intake air temperature sensor’s job is to take a measurement of the temperature of the incoming air (that the engine is breathing) and then send this info to the PCM. Once the PCM gets it, it uses this info to better calculate the mass of the air entering the engine.
What should intake air temp be in Toyota sesnor?
When your scan tool reports this DTC, the IAT sensor is reporting a temperature of 284 °F (140 °C) or hotter. P0113: Intake Air Temperature (IAT) Sensor Circuit High Voltage. When your scan tool reports this DTC, the IAT sensor is reporting a temperature of -40 °F (-40 °C) or colder. Bad gas mileage. Black smoke coming out of the tailpipe.
