P235ECylinder 11 Pressure Sensor Circuit Low

P235E indicates that the powertrain control module (PCM) has detected a low voltage signal from the cylinder 11 pressure sensor circuit, which is used to monitor combustion pressure for that specific cylinder. The PCM expects a voltage within a calibrated range, and a sustained low reading triggers this code, often affecting fuel delivery and ignition timing for that cylinder.
