P27C6Pressure Control Solenoid P Control Circuit Range/Performance

P27C6 indicates that the transmission control module (TCM) has detected an out-of-range or performance fault in the electrical circuit for pressure control solenoid 'P', which is one of the solenoids that regulates hydraulic pressure inside the automatic transmission. The computer compares the solenoid's commanded current or duty cycle against the actual pressure response and sets this code when the circuit's behavior falls outside the expected range.
