📌 Here are the Different Types of Sensors used in Vehicles:
1. Mass Air Flow Sensor:
A mass (air) flow sensor (MAF) is a sensor used to determine the mass flow rate of air entering a fuel-injected internal combustion engine.
2. Throttle Position Sensor:
A throttle position sensor is a sensor used to monitor the throttle body valve position for the ECU of an engine. The sensor is usually located on the butterfly spindle/shaft so that it can directly monitor the position of the throttle.
3. Oxygen Sensor:
An oxygen sensor, also known as an O2 sensor or lambda sensor, is a device that measures the amount of oxygen in a car's exhaust gas and helps the engine run efficiently.
4. Engine Knock Sensor:
The knock sensor is located on the outside of the engine block. It is intended to record knocking noise in all engine operating states to prevent engine damage.
5. Camshaft Position Sensor:
A camshaft position sensor is a vital component of a car's engine that measures the camshaft's position and rotation and sends this information to the engine control module (ECM).
6. Coolant Temperature Sensor:
A coolant temperature sensor (CTS) (also known as an ECT sensor or ECTS (engine coolant temperature sensor) is used to measure the temperature of the coolant/antifreeze mix in the cooling system, giving an indication of how much heat the engine is giving off.
7. NOx Sensor:
NOx sensors monitor the level of nitrogen oxide emitted by a diesel vehicle to ensure compliance with emissions regulations.
8. Manifold Absolute Pressure Sensor:
A manifold absolute pressure (MAP) sensor measures the pressure or vacuum in a car's intake manifold and provides information to the engine's electronic control unit (ECU).
