Circuit Description
PCM sensor power A (XDRP1) supplies 5 volts to the sensors identified on the preceding diagram. On DTS models, the purple
and yellow wire from pin F1 of PCM connector C connects to splice S101, which feeds all five identified sensors.
PCM sensor ground A (XDRG1) connects all ten sensors to ground through the PCM (pin E1 of connector C). The black and
orange ground circuit incorporates three splices (100A, 100B, and 100C).
