The primary 5-Volt Supply circuit originates in the Powertrain Control Module (PCM) and is split into two outputs. One output supplies the Crankshaft Position Sensor (CKP), Throttle Body Assembly and Power Distribution Center (PDC). The second output supplies the Accelerator Pedal Position Sensor (APPS). The PDC distributes this primary 5-Volt Supply to the Oil Pressure Sensor (OPS) and A/C Pressure Transducer.
