The Powertrain Control Module (PCM) continuously monitors Actual Line Pressure. If the Actual Line Pressure reading is greater than the maximum desired line pressure ever used in the current gear, while the Pressure Control Solenoid duty cycle is at or near its maximum value (which should result in minimum line pressure) for 3.5 seconds continuously, the DTC will set.
