| Circuit |
Description |
| 5 V Reference |
Regulated voltage supplied by the control module. |
| Terminal 2 @ B287 Shift Fork Position Sensor |
The control module input circuit has an internal resistance connected to 5 V. The sensor produces a PWM signal. |
| Terminal 3 @ B287 Shift Fork Position Sensor |
The control module input circuit has an internal resistance connected to 5 V. The sensor produces a PWM signal. |
| Low Reference |
Grounded through the control module. |
| Component |
Description |
| B287 Shift Fork Position Sensor |
The sensor contains a hall-effect sensor and additional electronics. It detects the strength of the magnetic field caused by a magnet that is mounted on the shift shaft in the transmission. |
| 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. |
