What does code P2372 mean?

Q: What does code P2372 mean?

Fuel Volume Regulator B Control Circuit Low. P2372 indicates that the powertrain control module (PCM) has detected a low-voltage condition on the control circuit for Fuel Volume Regulator B, which is typically a solenoid on the high-pressure fuel pump that meters fuel delivery. The PCM commands a duty cycle to the regulator and monitors the circuit for expected voltage; when the feedback voltage stays below the calibrated threshold, the code is stored and the PCM may limit fuel pressure or engine power.
