Air temperature sensors measure the temperature of the air being received by the engine through its intake(s) and relay that information to the ECU. Armed with this information, the ECU can calculate how oxygen-rich the intake air is and decide how much fuel to inject into the cylinders with the goal of balancing performance and fuel economy. Air temperature sensors are sometimes known as intake air temperature sensors (IATs). The ECU will add more fuel to cold, dense air and less to hot air because the oxygen molecules are further apart. It achieves this by altering the timing of the injector pulses. Engines with their cylinders arranged in a V-configuration can have two separate sensors to go with their separate intake manifolds.

Air temperature sensors can run into problems thanks to backfiring into the intake manifold, poor electrical connections somewhere in their circuits, or the simple passage of time putting strain on them and causing them to fail. When an air temperature sensor goes bad it can start sending inaccurate readings to the ECU which then injects the wrong amount of fuel into the cylinders. This can cause the engine to run rich or lean and can lead to all the undesirable side effects that those to unwelcome states can bring. Luckily, Automotive Superstore carries an extensive range of Fuelmiser air temperature sensors at very competitive prices so you needn’t drive around with your car or truck running rough for long.
