What does code P2294 mean?

Q: What does code P2294 mean?

Fuel Pressure Regulator 2 Control Circuit. P2294 indicates that the powertrain control module (PCM) has detected an electrical fault in the control circuit for fuel pressure regulator 2, which is typically the high-pressure fuel regulator on the engine's high-pressure fuel rail. The PCM monitors the circuit for expected voltage or current behavior and sets this code when the signal falls outside the normal range, often indicating an open circuit, short to ground, or short to power.
