Q: What does code P2366 mean?

Cylinder 12 Pressure Sensor Circuit. P2366 indicates that the powertrain control module (PCM) has detected an abnormal signal from the cylinder 12 pressure sensor, which is used to monitor combustion pressure for that specific cylinder. The PCM compares the sensor's voltage or signal pattern against expected values and sets this code when the reading falls outside the acceptable range or is erratic.
