Module, Powertrain Control (Pcm): 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)
