Temperature sensor, early Cherokee XJ 4.0L
Coolant temperature sensor (CTS) for early Cherokee XJ 4.0L
Thermistor performance is key to proper coolant temperature sensor operation. But on some OE-style temp sensors, the thermistor is encased in plastic and the life of the component can be shortened during the manufacturing process when excessively-hot material is injected into the housing.
WVE engineers solved the reliability issue by encasing the thermistor in thermal transfer paste formulated to transfer heat. The thermistor is attached to the connector housing using resistance welding, placed into a brass housing, and then the full assembly is crimp sealed to avoid thermal damage.
