SPN 5357 FMI 31 Code: Fuel System Problem Detected - Freightliner Q&A.

SPN 521052/FMI 31

Description This Code Sets When SPN 521050/FMI 31 has been Present for One Hour of Idle Time, the Vehicle has been Restarted or Six Gallons of Fuel has been Used.

SPN 521049/FMI 31

Description This Code Sets When There is a Code Present for the Diesel Exhaust Fluid (DEF) Tank Level, DEF Dosing Unit, DEF Pump, NOx Sensors, Blocked DEF Line, DEF Quality, NOx Efficiency, Selective Catalyst Reduction (SCR) Harness and/or SCR Sensor.

The 521031-16 fault is the "pressure deviation" fault.

Malfunctioning of high voltage system is referred to as drive motor 'B' position sensor circuit low. The position of internal component of hybrid motor is found by hybrid control module by using sensors. If any fault is found in the position sensor by high voltage system, ECM module will store the P0A47 error code.

The P0750 code indicates that the shift solenoid, which is one of the devices that controls the flow of transmission fluid within the unit, has malfunctioned in some way.

SPN stands for Suspected Parameter Number which tells you the circuit where the fault occurred. For example, if you had a SPN 1791 code, it would point to a fault detected in the EGR Valve Control Circuit. FMI stands for Failure Mode Indicator which tells you the reason the fault code was set.

Suspect Parameter Number (SPN): SPN is a diagnostic fault code assigned by the SAE to a specific part or electric subsystem.

SPN stands for Suspect Parameter Number. It's a diagnostic trouble code that provides detailed information about specific faults detected by the vehicle's ECU, making it easier to identify and address issues within the vehicle's electronic systems.

For example, you can get an FMI 31 code for having an empty DEF tank, or it may even be a code that informs you that the truck is in derate.

What is the code SPN 3719 FMI 31? ›

SPN 3719/FMI 31 - Silent Code that Logs when the Diesel Particulate Filter Regeneration Lamp is Flashing in "Regen Zone 2." NOTE: This code is informational only and used by service to help understand which dash lights illuminated during normal service.

The SPN 563 FMI 14 fault code is originating in the ABS system. The SPN 807 FMI 9 ABS code is a short to ground on the modulator valve. it's mounted to the frame near the rear axles. Repair the ABS fault first and more than likely you will see the transmission code go away.

SPN 1077/FMI 14 - GHG17

The Motor Control Module (MCM) monitors rail pressure during engine shut down and compares it to a stored learned value. If the bleed-down rate has changed due to leakage and it is below the learned value, this code will set.

SPN 3216/FMI 21 - EPA10

This diagnostic is typically Selective Catalyst Reduction (SCR) Inlet NOx Sensor - Drift (Low Box). This fault code may be set by an inlet NOx sensor drifted out of range with the engine at a low speed, low load (low box) situation.

This diagnostic is typically Diesel Particulate Filter (DPF) Pressure Out of Range Very High. This fault code sets when the DPF outlet pressure is greater than 35 kPa (5 psi) for more than 10 seconds.

The Diesel Intake Air Flow Position Sensor (DIAFPS) is typically located on the throttle body, which is mounted to the intake manifold or in a tube within the intake air stream. This sensor converts the incoming airflow volume into an electrical signal for the Powertrain Control Module (PCM).

A P0758 OBD-II error code is specifically associated with an electrical problem with the transmission shift solenoid “B” circuit.

Diagnostic trouble code (DTC) P2285 stands for “Injector Control Pressure Sensor Circuit Low.” This code can be logged when the powertrain control module (PCM) detects voltage or resistance that is lower than the appropriate range within the injector control pressure (ICP) sensor circuit.

The P0200 code is defined as “injector circuit malfunction.” In practice, this usually means that one or more of your fuel injectors have failed, causing their values to breach the range that the ECU, or PCM is familiar with.
