Q: What does code P235C mean?

Cylinder 11 Pressure Sensor Circuit. P235C indicates that the powertrain control module has detected an implausible signal from the cylinder 11 pressure sensor circuit, which is used on some engines to monitor combustion pressure for precise fuel and ignition control. The computer compares the sensor's voltage or signal pattern against expected values and sets this code when the reading falls outside the normal range or behaves erratically.
