94-18 Cummins Fault code 2215 is Fuel Pump Delivery Pressure - Data Valid But Below Normal Operating Range - Moderately Severe Level

Reason

Fuel Pump Delivery Pressure Low - Data Valid but Below Normal Operational Range - Moderately Severe Level. The ECM has detected that fuel pressure is lower than commanded pressure.

Effect

Possibly hard to start, low power, or engine smoke.

Component Location

The high-pressure fuel pump is mounted to the gear housing on the intake side of the engine. Refer to Procedure 100-002 in Section E.

Circuit Description

The pressure control loop relies on fuel pressure supplied to the high-pressure pump by the fuel gear 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 fuel pump actuator to supply more (or less) fuel to the high-pressure pump. The fuel flow circuit includes, in the following order: OEM fuel tank OEM fuel supply line Water stripping fuel filter (10 micron, water stripping, suction side fuel filter) Engine mounted OEM fuel connection Fuel supply tube to ECM cooling plate ECM cooling plate Fuel supply tube to the low-pressure gear pump Fuel supply tube to the pressure-side fuel filter Primary fuel filter (3 micron pressure-side fuel filter) Fuel supply tube to the high-pressure pump High-pressure pump High-pressure system (including fuel rail and fuel rail pressure relief valve), injectors, and high-pressure lines.

Fault Code 2215 sets when the engine is running and measured rail fuel rail pressure remains at least 10 Mpa [1450 psi] less than commanded pressure. Once detected, Fault Code 2215 will remain active until the engine is turned off or until the measured fuel rail pressure matches the commanded fuel rail pressure. When a condition exists that causes Fault Code 2215 to become active, it is typical for the fault code to become active when the engine is heavily loaded and become inactive when the engine is lightly loaded.

When Fault Code 2215 occurs, the fuel system has lost its ability to maintain fuel rail pressure. Causes of this fault include:

  • Excessive fuel inlet restriction
  • Fuel filter plugging
  • Air in the fuel system
  • Fuel gear pump output low
  • Fuel gear pump pressure regulator sticking or leaking
  • High-pressure pump capacity decay (high leakage to drain from the high-pressure pump)
  • Fuel rail pressure relief valve leaks to drain
  • Fuel rail pressure relief valve opens at too low a pressure
  • Injector fuel circuit leaks to drain
  • Pressure sensor reads more than 10 Mpa [1450 psi] lower than actual pressure.
