DTC codes / P23xx · Ignition system and misfire / P235F
P235F indicates that the powertrain control module (PCM) has detected an abnormally high voltage signal from the cylinder 11 pressure sensor circuit. This sensor, used on engines with cylinder pressure monitoring for combustion feedback, reports a voltage above the expected range, which the PCM interprets as a circuit fault rather than a valid pressure reading.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
