Description of DTC code P2293

The fuel pressure regulator maintains appropriate and constant fuel pressure. It allows the fuel system to release excess fuel to be sent to the tank.

The diagnostic code P2293 OBDII indicates that the Powertrain Control Module (PCM) detects the fuel pressure regulator voltage is out of the range specified by the pressures stored in the memory. In other words, the commanded fuel pressure is not the actual pressure detected by the regulator.

Symptoms of fault code P2293

  • Check Engine Lamp illuminated.
  • Problems when accelerating.
  • Higher fuel consumption.
  • Other fault codes were

Causes of OBD2 P2293

Reason to set the P2293 OBD2 trouble code :

  • Incorrect fuel pump output.
  • There may be blockages in the fuel filter.
  • Fuel lines may be damaged.
  • The fuel pressure regulator may be faulty.
  • Possibly, the Fuel Rail Pressure Sensor (FRP) is in bad condition.

Possible solutions of the DTC code P2293

To resolve the faults associated with the P2293 OBDII error code, try this:

  • Use a pressure gauge to check the fuel pressure. If the result is within the manufacturer's specifications, the Fuel Rail Pressure Sensor may be sending an incorrect reading to the PCM.
  • Check the fuel filter and make sure it is not clogged. Replace it if necessary.
  • Check the voltage battery at the positive terminal of the fuel pump. If you find low power, check the cables and connectors. Also, check the ground signal. Repair as necessary.
  • Check the fuel lines for damage such as clogs or damage from knocks. Repair or replace.
  • Check the fuel pressure regulator, and verify that it is not leaking.
  • Test that the FRP Sensor has the resistance level indicated by the manufacturer in the specifications. Also, check the reference voltage. Replace it if the results do not match with those specified.
