P0972 MeaningA/T clutch pressure control solenoid valve C is used for clutch pressure control. A spool in A/T clutch pressure control solenoid valve C pushes the valve according to the duty cycle that is controlled by the Powertrain Control Module (PCM) (The hydraulic pressure is proportional to the current). The PCM measures the current flowing through A/T clutch pressure control solenoid valve C and uses feedback control to compensate for the difference between the actual current and the commanded one. If the measured current for the PCM output duty cycle is not within a specified range (circuit short or open), the PCM detects a malfunction and stores a Diagnostic Trouble Code (DTC).
