P2293 code definition

Fuel Pressure Regulator 2 Performance

What the P2293 code means

P2293 is an OBD-II generic code for the Engine Control Module (ECM), detecting the injector fuel pressure regulator is not within specification voltages all the time for what the commanded pressures are supposed to be at. There is a difference of commanded fuel pressure and actual pressure sensed by the regulator.

What causes the P2293 code?

  • The ECM controls and monitors the fuel injectors fuel pressure and if the commanded fuel pressure is lower or higher than is commanded then the code is set.

  • The fuel pressure regulator is internally out of specifications.

  • The fuel filter is clogged or the fuel pump is failing.

What are the symptoms of the P2293 code?

  • The Check Engine Light will be illuminated and the code is set in ECM memory as a fault.

  • The engine may run low on power or not have a limited RPM, depending on how low the fuel pressure is and the failure reason.

  • The engine may run good, but lack top end speeds.

How does a mechanic diagnose the P2293 code?

  • Scan for codes and document the codes in the ECM, and look at the freeze frame data for failure.

  • Check if the fuel filter is not clogged.

  • Check fuel pressures with a gauge attached and compare this to the fuel pressure regulator readings.

  • Check if the fuel pressure regulator resistance is within specifications.

  • Check the fuel pump inlet in the tank to see if it is clogged or restricted.

Common mistakes when diagnosing the P2293 code?

  • Clearing ECM memory codes before checking the freeze frame data for the main failure problem, so the failure may be duplicated and repaired.

  • Replacing the high pressure fuel pump when the filter is clogged.

How serious is the P2293 code?

Code P2293 is a code indicating that the fuel pressure is different than commanded to the injectors by the ECM. The problem may cause various problems due to the fuel pressure being too low or high, if the sensor is failing or failed.

What repairs can fix the P2293 code?

Additional comments for consideration regarding the P2293 code

Code P2293 is caused most commonly from erratic fuel pressure from the filter being clogged or the fuel pump failing intermittently. If an engine has been replaced on some vehicles, then verify that the new fuel pressure regulator sensor part numbers are the same or it will set a code.
