| 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. |
The control module consists of 4 internal 5 V reference circuits. The 5 V reference circuit provides 5 V for one or more sensors. All sensors will be affected when a short to ground or voltage is on a shared 5 V reference circuit.
