CM850 Electronic Control System – FAULT CODE 2292

Fuel Inlet Meter Device – Data Valid but Above Normal Operational Range – Moderately Severe Level


Fault Code: 2292
FMI: 16
LAMP: Amber

Fuel Inlet Meter Device – Data Valid but Above Normal Operational Range – Moderately Severe Level. The flow demand is higher than expected.

Possibly hard to start; low power; possible engine smoke. Engine power is derated.

Fuel System

Circuit Description

The fuel pressure control loop relies on fuel pressure supplied to the high-pressure pump by the electric lift pump and low-pressure pump. The electronic control module (ECM) monitors rail fuel pressure and engine operating conditions and changes the flow command to maintain the proper rail fuel pressure. Changes to the flow command result in opening (or closing) of the electric fuel control actuator to supply more (or less) fuel to the high-pressure pump.

The fuel flow circuit includes, in the following order of fuel flow:

  • Fuel tank
  • OEM fuel supply line
  • OEM 300 micron filter
  • ECM cooling plate
  • Electric lift pump
  • Fuel filter
  • Gear pump
  • Electronic fuel control actuator
  • High-pressure fuel pump
  • Fuel rail (includes rail pressure relief valve and pressure sensor)
  • High-pressure fuel lines
  • High-pressure fuel connectors (HPCs)
  • Injectors
  • Return to tank.

Component Location

The electronic fuel control actuator is located on the fuel pump. 100-002 (Engine Diagrams) in Section E for a detailed component location view.

Shop Talk

Causes of this fault code include the following: High inlet restriction, plugged fuel filter, low lift pump pressure, low resistance to the electronic fuel control actuator, stuck or restricted electronic fuel control actuator, system return (excessive return flow from the injectors, high-pressure pump, or rail pressure relief valve), or tampering.

Fault Code 2292 sets when the ECM commands the electronic fuel control actuator to open more than expected to maintain rail pressure. Fault Code 2215 sets when the ECM opens the electronic fuel control actuator to fully open and rail pressure is still lower than commanded.

Once the repair has been made, this fault code will require approximately 15-20 minutes of road test or dynamometer run to be set inactive.
