What does code P2355 mean?

Q: What does code P2355 mean?

Cylinder 10 Pressure Sensor Circuit High. P2355 means the powertrain control module (PCM) has detected an abnormally high voltage on the signal circuit of the cylinder 10 pressure sensor, which is used to monitor combustion pressure for that specific cylinder. The sensor's output is outside the expected range, so the PCM cannot trust the cylinder 10 pressure data for fuel and ignition control.
