Summary
  • The diagnostic trouble code (DTC) P2293 indicates “Fuel Pressure Regulator 2 Performance.”
  • The powertrain control module (PCM) will set this code when it detects the wrong pressure in fuel pressure regulator 2.
  • Common causes of the P2293 code are a faulty fuel pressure regulator, fuel pump failure, and clogged fuel filter.
  • A vehicle that sets a P2293 code can show symptoms like an illuminated check engine light, poor engine performance, and the engine stalling or failing to start.

On-board diagnostic (OBD) codes help mechanics and vehicle owners identify possible issues in a vehicle. To troubleshoot and resolve these problems, it’s important to know what these codes mean.

Code P2293 is one of many trouble codes that can be logged and retrieved from the OBD system. Here is some helpful information that can help you understand what getting this code can mean for your vehicle.

What Does the P2293 Code Mean?

Diagnostic trouble code (DTC) P2293 stands for “Fuel Pressure Regulator 2 Performance.” This code is logged when the powertrain control module (PCM) detects that the fuel pressure regulator is not operating properly.

On this kind of system there is one fuel pressure regulator in the high pressure pump and a second regulator in the end of the fuel rail. The regulator in the pressure pump is operated with a duty cycle carefully timed to control pump volume based on the pump’s piston strokes. Fuel Pressure Regulator 2 is an actuator that precisely controls fuel rail pressure based on feedback from the fuel rail pressure sensor.

P2293 code is logged when the powertrain control module (PCM) detects that the fuel pressure regulator is not operating properly.

Typically a “Performance” code like this one indicates that the ECM/PCM sent a command and determined that the commanded target wasn’t met.

The fuel pressure regulator keeps the fuel pressure steady and lets the fuel system release excessive fuel in the fuel rail back to the fuel tank. It can be found built into the fuel rail assembly in some vehicles. If the vehicle has a returnless fuel supply, the regulator is a part of the fuel pump module inside of the tank.

The PCM controls returnless fuel systems. Once the PCM has detected that the fuel pressure commanded is not within specifications on fuel pressure regulator designated 2, it will set error code P2293.

Depending on the severity of the problem, related error codes might also be stored with this DTC. Code P2293 is similar to error codes P2294, P2295, and P2296.

Note: The definition of code P2293 might be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.
