Q: What does code P235D mean?

Cylinder 11 Pressure Sensor Circuit Range/Performance. P235D indicates that the powertrain control module (PCM) has detected an out-of-range or performance fault in the cylinder 11 pressure sensor circuit, which is typically used on engines with cylinder pressure sensors for precise combustion monitoring. The PCM compares the sensor signal against expected values and flags the code when the signal is too high, too low, or erratic for the current operating conditions.
