Yes, the ambient air temperature sensor can significantly affect the engine. This sensor plays an essential role in how the engine functions and performs. The sensor provides information to the Engine Control Unit (ECU) about the temperature of the air outside. The ECU then uses this information to make vital adjustments to the engine’s air-fuel mixture, ignition timing, and other factors. 1. Air Density: Cold air is denser than warm air. Therefore, more oxygen is present in a specific volume of cold air than the same volume of warm air. More oxygen means that more fuel can be burned and thus, more power can be produced. So by sensing the cold air, the ECU increases the amount of fuel injected into the engine to generate more power. 2. Fuel Injection: If the air temperature is warm, less fuel will be injected into the engine and if the air temperature is cold, more fuel will be injected. This happens because warmer air leads to better fuel atomization which in turn makes the fue...
