Complete Guide to Automotive Sensors: Temperature, Pressure, Position, and Oxygen Sensors

Modern vehicles are no longer just mechanical systems—they are intelligent machines that rely on a network of electronic sensors working together. These sensors manage everything from engine performance and emissions control to driving comfort and safety features. In this post, we’ll explore the major automotive sensors, categorized by function.     1. Temperature Sensors ECT Sensor (Engine Coolant Temperature) : Measures coolant temperature and sends data to the ECU for fuel injection and ignition timing control. IAT Sensor (Intake Air Temperature) : Measures air temperature entering the intake manifold to calculate air density. Thermistor Switch : Acts as an ON/OFF switch at a specific temperature to control radiator fans, heaters, or compressors. 2. Pressure Sensors MAP Sensor (Manifold Absolute Pressure) : Monitors pressure in the intake manifold for fuel and timing adjustments. TPMS (Tire Pressure Monitoring System) : Detects real-tim...
