Coolant Temperature Sensor
A coolant temperature sensor is a component that measures the temperature of the engine coolant and sends this information to a gauge or the vehicle's engine control module. The coolant temperature sensor is typically located on the engine block or cylinder head and operates using a thermistor or thermocouple to measure the temperature of the coolant as it flows through the engine. The coolant temperature sensor functions by providing the engine control module with information about the engine's operating temperature, which allows the module to adjust engine performance and optimize fuel efficiency. For example, the engine control module may adjust the air/fuel ratio, ignition timing, or idle speed based on the temperature reading from the coolant temperature sensor. A malfunctioning coolant temperature sensor can cause a range of problems, including inaccurate temperature readings, engine overheating, or reduced engine performance.

When choosing a replacement coolant temperature sensor, first confirm the year, make, model, and engine size of your vehicle. For custom setups, such as aftermarket fuel injection kits or gauges, confirm the readings on the sensor match the requirements of the EFI system or gauge. From the remaining compatible options, choose the sensor that best fits your application needs.
