P233DFuel Pressure Regulator B Solenoid Supply Voltage Control Circuit Open

P233D indicates that the powertrain control module (PCM) has detected an open circuit in the supply voltage control circuit for the fuel pressure regulator B solenoid. This means the electrical path that powers the solenoid is broken, so the PCM cannot command the solenoid to adjust fuel pressure, which may affect engine performance and emissions.
