What does code P2349 mean?

Q: What does code P2349 mean?

Cylinder 9 Pressure Sensor Circuit Range/Performance. P2349 indicates that the powertrain control module (PCM) has detected an out-of-range signal from the cylinder 9 pressure sensor, which is typically a fuel pressure or combustion pressure sensor used for precise fuel injection timing and quantity control. The PCM compares the sensor's voltage or signal against expected values for the current operating conditions and sets this code when the signal falls outside the acceptable range or does not correlate with other sensor inputs.
