SUBJECT: COOLANT SENSOR KIT
MODELS: 1980-84 LIGHT DUTY MODELS EQUIPPED WITH COMPUTER COMMAND CONTROL
All 1980-84 Caballeros and all 1980-84 vehicles equipped with NB2 California emissions were built with engines incorporating computer command control. Many coolant sensors have been replaced on these vehicles as a result of a "Check Engine" light and Code 15. In many cases, the sensor was 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 GM vehicles 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.
