Temperature sensors provide critical thermal data to the Engine Control Unit (ECU) from various points, including coolant, intake air, and oil. This information is vital for regulating fuel mixture, ignition timing, cooling fan operation, and engine protection strategies. A faulty sensor can cause poor running, overheating, or false warning lights. ECT AutoCore Trading supplies a full range of precision temperature sensors. Engineered for fast response and accurate readings in harsh environments, our sensors ensure the ECU receives reliable data to optimize engine performance, efficiency, and thermal management for both petrol and diesel applications.
