Intake Air Temperature Sensor – Repairs & Replacement in Hamilton

What does the air temperature sensor do?IAT Sensor Repairs Hamilton NZ

Air is essential to the operation of your car’s engine. Inside the engine, it is mixed with fuel and ignited. This provides your engine with the necessary power to operate. The intake air temperature sensor (or IAT sensor) monitors the temperature of air entering your engine and helps to create an optimum ratio of air and fuel inside your car’s engine. This improves your engine’s running condition, performance and fuel economy.

The air temperature sensor is a thermistor, which means that its electrical resistance changes in relation to air temperature. The electrical signal is sent to your car’s onboard computer, which uses the information to determine air density and alter fuel injection accordingly. Cold air is denser than hot air, meaning that more fuel needs to be injected into the engine to create an ideal air/fuel ratio.

Problems with the air temperature sensor can affect the levels of air and fuel in your car’s engine. This can affect your engine’s performance by hindering its ability to correctly burn fuel.

Symptoms of a faulty air temperature sensor:

  • Check engine light is on – If the air temperature sensor fails or the wiring to air temperature sensor fails then this will most often make the Check Engine Light turn on your dash board. Also any significant changes in your engine’s air/fuel ratio will trigger the check engine light on your car’s dashboard. Plugging a scan tool into your car will allow you to learn more information about the fault, such as whether the air/fuel mixture is too lean or rich.

  • Increased misfires  A misfire occurs when your engine doesn’t burn fuel properly, resulting in increased exhaust emissions. An incorrect air/fuel ratio will increase how often misfires occur.
  • Increased fuel consumption – A failing air temperature sensor will cause the wrong amount of fuel to enter your engine, resulting in it not burning correctly and going to waste.
  • Rough idle – A faulty air temperature sensor will also cause your engine to idle roughly. This means it will idle loudly, with vibrations, shaking and inconsistent RPM.
