Fuel Pressure Regulator 2 Control Circuit
What does P2294 mean?
The P2294 code means the vehicle's onboard diagnostic system has detected: Fuel Pressure Regulator 2 Control Circuit. This is a moderate severity code.
Common Symptoms
- Check Engine Light illuminated
- Engine running rough at idle
- Poor fuel economy
- Hesitation during acceleration
- Hard starting after the vehicle sits
Probable Causes (Ranked by Likelihood)
- Failed fuel pressure regulator solenoid Very High
- Damaged wiring to fuel pressure regulator High
- Corroded connector at regulator solenoid Moderate
- ECM driver circuit fault for regulator Low
Step-by-Step Diagnostic Procedure
-
Check the fuel pressure regulator solenoid connector for corrosion
-
Measure resistance of the regulator solenoid coil
-
Inspect wiring from ECM to fuel pressure regulator
-
Verify ECM is commanding the regulator correctly with scan tool
-
Check for voltage at the regulator connector with key on
Frequently Asked Questions
Can I drive with code P2294?
Short distances only. The fuel pressure may not be regulated correctly, causing drivability issues and potential engine damage over time.
What causes P2294?
Usually a failed fuel pressure regulator solenoid or damaged wiring. Direct injection vehicles are more prone to this code due to higher fuel pressures.
Is P2294 expensive to fix?
Typically $150 to $600. The solenoid is often replaceable separately from the entire regulator assembly, which keeps costs lower.
