Q: What does code P1250 mean?

Pressure Regulator Control Solenoid Circuit. P1250 on a Mazda indicates that the powertrain control module (PCM) has detected an electrical fault in the pressure regulator control solenoid circuit, which manages fuel pressure in the high-pressure fuel system. The PCM monitors the solenoid's command signal and feedback circuit, and when the voltage or current falls outside the expected range, it stores this code and may illuminate the check engine light.
