MODULE, Powertrain Control: Operation: Operation: Overview

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

• Camshaft Position Sensor (5 V secondary)
• Crankshaft Position Sensor (5 V primary)
• EGR Position feedback sensor (5 V secondary) (if equipped)
• Engine coolant temperature sensor (connected to 5 V internal via a pull up resistor)
• Inlet Air Temperature Sensor (connected to 5 V internal via a pull up resistor)
• Knock sensor (connected to 5 V internal via a pull up resistor)
• Manifold absolute pressure sensor (5 V secondary)
• Oil Pressure Switch (connected to 5 V internal via pull up resistor)
• Pedal Value Sensor #1 (5 V Primary)
• Pedal Value Sensor #2 (5 V Secondary)
• SRV Position Feedback Sensor (5 V Secondary)
• Throttle Position Sensors (5 V Primary)
• Variable Line Pressure Sensor (5 V Secondary)
