It threads into the engine oil system with a 1/2-14 NPT fitting and sends temperature readings to the gauge or engine control module, helping prevent overheating and maintain proper oil viscosity. The sensor is a direct replacement for Kenworth OEM part number 17-04184 and is commonly replaced when the oil temperature gauge becomes erratic or the sensor fails, causing inaccurate temperature readings. Although the inventory listing describes it as a differential temperature sensor, all verified cross-references and manufacturer data identify it as an oil temperature sensor.
