Powertrain Control Module - Operation

OPERATION

The PCM supplies two regulated 5 volts supplies - a 5V primary and a 5V secondary (auxiliary) to the following sensors:

- Camshaft Position Sensor (5V secondary)

- Crankshaft Position Sensor (5V primary)

- EGR Position feedback sensor (5V secondary) (if equipped)

- Engine coolant temperature sensor (connected to 5V internal via a pullup resistor)

- Inlet Air Temperature Sensor (connected to 5V internal via a pullup resistor)

- Knock sensor (connected to 5V internal via a pullup resistor)

- Manifold absolute pressure sensor (5V secondary)

- Oil Pressure Switch (connected to 5V internal via pullup resistor)

- Pedal Value Sensor #1 (5V Primary)

- Pedal Value Sensor #2 (5V Secondary)

- SRV Position Feedback Sensor (5V Secondary)

- Throttle Position Sensors (5V Primary)

- Variable Line Pressure Sensor (5V Secondary)
