What are the common engine sensors?
1 Answers
There are 6 common engine sensors. Here are the detailed introductions: 1. Crankshaft Position Sensor: The crankshaft position sensor is used to detect engine speed and provide crankshaft rotation angle. It is installed near the flywheel. 2. Coolant Temperature Sensor: Used to detect the temperature of the cooling system to ensure the engine operates at an appropriate temperature. It is installed on the engine water passage. 3. Intake Air Temperature Sensor: Used to detect the temperature of air entering the engine, mainly to adjust fuel injection volume. When the external temperature is too low, it increases fuel injection; when too high, it reduces fuel injection. It is installed on the intake bellows. 4. Intake Pressure Sensor: Used to determine the fuel injection pulse width and ignition advance angle of the engine. It is generally installed on the intake manifold. 5. Camshaft Position Sensor: Also known as the phase sensor, it is installed near the camshaft. 6. Oxygen Sensor: To control vehicle emissions, the ECU monitors the concentration of exhaust gases to adjust fuel injection, bringing the actual air-fuel ratio closer to the theoretical air-fuel ratio. The oxygen sensor serves this function and is usually installed on the exhaust manifold.
