Q: What does code P2348 mean?

Cylinder 9 Pressure Sensor Circuit. P2348 indicates that the powertrain control module (PCM) has detected an abnormal signal from the cylinder 9 pressure sensor circuit, which is used on engines with in-cylinder pressure monitoring to fine-tune combustion. The PCM compares the sensor voltage to expected values and sets this code when the signal falls outside the valid range or is implausible.
