| 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 |
|---|---|
| B131 Exhaust Temperature Sensor | The temperature sensor is a positive temperature coefficient thermistor, a resistor which changes based on temperature. |
| 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. |
