Code P2296 GMC Description

The Engine Control Module (ECM) controls a series of actuators to ensure optimal engine performance. The control module does this by reading values from a variety of sensors, interprets the data, and adjusts the engine actuators accordingly. The fuel pressure regulator is the solenoid valve that controls the pressure in the fuel rail. The Diagnostic Trouble Code (DTC) will be set when the control circuit is short to voltage for greater than 0.275 s.
