What does code P2371 mean?

Q: What does code P2371 mean?

Fuel Volume Regulator B Control Circuit Performance. P2371 indicates that the powertrain control module (PCM) has detected an out-of-range performance condition in the control circuit for Fuel Volume Regulator B, which is a solenoid valve that meters fuel pressure or flow on the high-pressure side of the fuel system. The PCM commands a specific current or duty cycle to the regulator and monitors the circuit for expected voltage or current feedback; when the feedback does not match the command within a calibrated window, the code is stored.
