What are the symptoms of an intake air temperature sensor failure?

[StellaMarie]

Intake air temperature sensor failure symptoms: 1. The engine malfunction indicator light stays on in the ON position; 2. A small amount of black smoke appears when gently pressing the throttle in neutral, and a large amount of black smoke during rapid acceleration; 3. The engine lacks power; 4. Fault code: P01D6. The intake air temperature sensor primarily corrects the engine's fuel injection quantity and plays a crucial role in the automotive engine system. Except for the Karman vortex air flow sensor, all other engines are equipped with an intake air temperature sensor. The intake air temperature sensor can be installed inside the air flow sensor or the intake pressure sensor, or at a certain location on the intake manifold. When the engine intake air temperature is high, the control unit reduces the fuel injection pulse width, and vice versa.
