Many coolant sensors have been replaced on 1980 to 1984 vehicles as a result of a "Check Engine" Light and Code 15. In many cases, the sensor was not defective, and the real cause was a poor connection between the sensor and the wire harness connector.
An improved coolant sensor and connector kit, P/N 10045847, containing all necessary parts, has been released for all 1980-84 cars and 1982-84 Light Duty Trucks using Computer Command Control. This sensor is used to provide coolant temperature information to the Electronic Control Module (ECM). Separate sensors are used for gage or warning light operation, or to activate the electric cooling fan, and are not affected.
