Engine Speed Sensor: Monitors the rotational speed of the engine's crankshaft or camshaft. The ECU uses this information to control fuel injection quantity, ignition timing (if applicable), and other engine functions based on the engine's speed. The input range for the engine speed sensor is typically from 0 to [X] RPM, with a high level of accuracy to ensure precise control.
Temperature Sensors:
Coolant Temperature Sensor: Measures the temperature of the engine coolant. The ECU uses this data to adjust the fuel injection and ignition timing (if applicable) to optimize engine performance under different temperature conditions. The sensor has a measurement range of approximately -40°C to 130°C.
Intake Air Temperature Sensor: Monitors the temperature of the incoming air. This information helps the ECU calculate the density of the air and adjust the fuel injection accordingly to maintain the correct air-fuel ratio. The measurement range is usually from -40°C to 120°C.
