Circuit/System Description

WARNING: This page is about a different car, the 2018 Buick Encore. However, it is still accessible from the selected car via links, so may be relevant.

For an overview of the component/system, refer to:Cooling System Description and Operation (LUV, LE2)Cooling System Description and Operation (2HO)

Circuit Description
Signal The control module input circuit has an internal resistance connected to 5 V.
Low Reference Grounded through the control module.
Component Description
B34 Engine Coolant Temperature Sensor The sensor is a negative temperature coefficient thermistor. As the temperature of the fluid/metal increases, the resistance of the sensor decreases, varying the voltage on the signal circuit.
K20 Engine Control Module The control module contains a microprocessor used to process input data to control outputs.
The control module controls a series of actuators to ensure optimal engine performance. The control module does this by reading values from a variety of sensors, interprets the data and adjusts the engine actuators accordingly.
