This air temperature sensor measures the intake air temperature in the electrical system of the host tractor. It provides a signal to the engine control unit, which uses the reading to adjust fuel delivery and injection timing for optimal combustion. A failed sensor can cause incorrect air-fuel mixture, leading to reduced power, increased exhaust temperature, or erratic idle. The sensor is manufactured to match the original component's electrical resistance curve and connector interface, ensuring the control unit receives the correct voltage signal without additional wiring modification.
