The coolant temperature sensor (CTS) is a critical engine management component that measures the temperature of the engine coolant. The Engine Control Unit (ECU) uses this data to adjust fuel injection timing, ignition timing, and operate the electric cooling fans. A faulty sensor can lead to poor fuel economy, rough idling, hard starting, and overheating. This category provides exact-fit OE-specification replacement sensors featuring high-quality thermistors and corrosion-resistant brass housings for rapid, accurate temperature readings. Select your vehicle to find the reliable sensor required to restore perfect engine performance and efficiency.
It provides the ECU with precise data, which is essential for correct fuel injection and timely activation of the cooling fan.
