Summary
  • Diagnostic trouble code (DTC) P2294 has the definition of “Fuel Pressure Regulator 2 Control Circuit/Open.” If the powertrain control module (PCM) detects a problem with the fuel pressure regulator (designated #2) or its circuit, then it might trigger code P2294.
  • The P2294 code can be caused by a faulty fuel pressure regulator, faulty fuel pump, wiring issues, or a failed PCM.
  • When a P2294 is triggered, your vehicle can show symptoms like poor engine performance, increased fuel consumption, and a stalling engine.

The fuel pressure regulator works with the fuel pump to maintain the ideal pressure drop at the injector tips. It is a spring-loaded and diaphragm-operated valve in a metal housing that’s controlled by the powertrain control module (PCM). If the fuel pressure regulator is unable to send a voltage signal to the PCM, on-board diagnostics (OBD) will log a P2294 code.

What Does the P2294 Code Mean?

Diagnostic trouble code (DTC) P2294 stands for “Fuel Pressure Regulator 2 Control Circuit/Open.”

The fuel pressure regulator controls the pressure delivered to the fuel injectors in the engine. On older vehicles, the fuel pressure regulator is controlled by an engine vacuum. In most newer vehicles, however, the pressure regulator is managed by the PCM.

If the PCM detects a problem with the fuel pressure regulator (designated #2) or its circuit, the module might set code P2294.

Note: The definition of code P2294 might be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.

How to Diagnose the P2294 Code

DTC P2294 is a generic powertrain code that can be logged in vehicles with an OBD-II system. However, keep in mind that vehicle specifications can alter the steps for diagnosis and repair.

If you’re not familiar with the diagnostic process, you might want to have a certified mechanic do the job for you to ensure that all steps and protocols are followed correctly. Otherwise, you can go ahead and do it yourself.

How to Fix the P2294 Code

Attempting to fix a P2294 code can be tricky without the right tools and technical knowledge. It can even lead to further complications if done incorrectly. Under these circumstances, it might be best to take your vehicle to the nearest repair shop and have a trained professional perform the necessary repairs.

But if you think you’ll do fine on your own, keep in mind that there’s no umbrella fix that will work for all makes and models, which is why it’s important to consult vehicle-specific manuals. Guides like those from Chilton or an ALLDATA subscription contain instructions that are tailor-fit for makes and models, so you might want to check those out before you begin.
