Circuit Description

The PCS is a PCM-controlled device used to regulate transmission line pressure. The PCM compares TPS voltage, engine RPM, and other inputs to determine the line pressure appropriate for a given load. The PCM will regulate the pressure by applying a varying amperage to the PCS. The applied amperage can vary from 70 to 1060 milliampere (mA), and is monitored by the PCM.

This DTC detects a continuous open or short to ground in the PCS circuit or the PCS. This is a type "C" DTC.
