DTC codes / P23xx · Ignition system and misfire / P233E
P233E indicates that the powertrain control module (PCM) has detected a low voltage condition on the supply control circuit for the fuel pressure regulator B solenoid, which is typically the solenoid responsible for controlling fuel pressure in a specific circuit or bank. The PCM monitors the voltage on the control side of the solenoid and sets this code when the voltage falls below the expected threshold, indicating a short to ground, an open circuit, or a faulty solenoid.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
