About Sensors

Find and browse Sensors on Buy & Sell Car Online, a global automotive marketplace connecting buyers with professional suppliers and private sellers offering electronic components essential for engine monitoring and control. This category includes engine sensors used in passenger cars, SUVs, vans, and light commercial vehicles to measure and report critical operating parameters to the engine control unit. Typical listings cover crankshaft and camshaft position sensors, oxygen sensors, mass air flow sensors, manifold absolute pressure sensors, throttle position sensors, coolant temperature sensors, knock sensors, and other model-specific sensing devices. Engine sensors provide real-time data that allows the ECU to adjust fuel injection, ignition timing, air–fuel mixture, and emissions control for efficient and reliable engine performance. Faulty or inaccurate sensors can lead to warning lights, poor drivability, increased fuel consumption, rough idling, or emission system issues. Buyers can review specifications, signal types, connector designs, and compatibility information to ensure correct fitment. Compare offers and use filters by vehicle make and model to find suitable sensors for diagnostics, maintenance, or engine electronics repair needs.
