Circuit/System Description

WARNING: This page is about a different car, the 2022 Cadillac CT4. However, it is still accessible from the selected car via links, so may be relevant.
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
B13M Manual Transmission Fluid Temperature Sensor The temperature sensor is a negative temperature coefficient thermistor, a resistor which changes based on temperature.
  • Low temperature produces a high resistance: 101 kohms @-40°C (-40°F)
  • High temperature produces a low resistance: 47.5 ohms @ 150°C (302°F)
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.
