Title : SPN 3055 FMI 17 FRP above maximum with minimum command Troubleshooting
Applies To : EPA 2010 MaxxForce 11 / 13

SPN 3055 FMI 17 - FRP Above Maximum with Minimum Command
Condition / Description

Setting Criteria

Enable Conditions / Values

Time
Required

FRP governor deviation below
minimum limit

FRP governor error less than 725 PSI at 600750 RPM

Key ON

10 seconds

ECM Not in limp-home mode
Metering unit flow < 327670 mm3/sec
Engine speed > 0 rpm OR Fuel Rail Pressure > 90000 kpa for more than 20
engine revolutions
Fuel injector quantity command > 5 mg/stroke
ECT1 > ­40°F (­40°C) Engine Not overrunning
Fault Overview
Fault code sets when the Engine Control Module
(ECM) detects Fuel Rail Pressure (FRP) exceeds
13053 psi (90000 kPa) when the Fuel Pressure
Control Valve is commanded to minimum pressure.
Malfunction Indicator Lamp (MIL) Reaction
MIL will illuminate when this fault is detected during two consecutive drive cycles.
Associated Faults
SPN 94 FMI 0 (FDP); SPN 157 FMI 3, 4, 20, 21 (FRP);
and SPN 633 FMI 3, 4, and 5 (FPCV)
Drive Cycle to Determine Fault Status
Drive Cycle 2 in 2013 HD-OBD Diagnostic Reference
Manual.
Possible Causes
• Restricted high-pressure pump fuel return line
• Fuel Pressure Control Valve (FPCV) or circuit fault

StepAction
1

Check fuel level. Read fuel level using the vehicle instrument panel gauge and perform a
Yes: Go to step 2.
visual inspection of fluid level in the fuel tank.
Is sufficient fuel in the fuel tank and not leaking?

StepAction

Decision

No: Add fuel or repair leaks, and prime engine.

Decision

Using Electronic Service Tool (EST) with ServiceMaxx™ software, check Diagnostic
Yes: Go to step 3.
Trouble Code (DTC) list for SPN 94 FMI 0 (FDP); SPN 157 FMI 3, 4, 20; and 21 (FRP) or
SPN 633 FMI 3, 4, and 5 (FPCV).
No: Repair SPN 94 FMI 0; SPN 157 FMI 3, 4, 20, and 21; and SPN 633 FMI 3, 4, and 5.
See health report for link to diagnostics.
Is the EST DTC list free of SPN 94 FMI 0; SPN 157 FMI 3, 4, 20, and 21; and SPN 633
FMI 3, 4, and 5?

3

Check for restricted fuel return line. Perform HP Pump Fuel Return Pressure Test (page
174).

Yes: Go to step 4.
No: Repair restriction in fuel return line between high-pressure fuel pump and fuel tank.

Is pressure < 13 psi?

StepAction

Decision

4

Yes: Verify each step was completed correctly and if SPN 3055 FMI 17 remains notify
supervisor.
No: Replace Fuel Pressure Control Valve.

Check for a failed FPCV. Using EST, perform the High Pressure Pump Test (see page
180).
Does the pressure differential maintain < 80 bar or 1160 PSI throughout the test?

NOTE: After performing all diagnostic steps, if SPN 3055 FMI 17 remains, verify each step was completed correctly and the proper decision was made. Notify supervisor for
further action.
