The SPN 3250 FMI 31 fault code indicates an abnormal temperature rise in the Diesel Oxidation Catalyst (DOC) of a diesel engine. This diagnostic trouble code is triggered when the Engine Control Module (ECM) detects a temperature reading from the DOC that exceeds expected parameters, suggesting potential issues with the aftertreatment system.What SPN 3250 FMI 31 MeansThe SPN 3250 FMI 31 fault code

The SPN 3250 FMI 20 fault code indicates a temperature drift issue within the Diesel Oxidation Catalyst (DOC) system, specifically when the inlet temperature is too low or the outlet temperature is too high. This diesel engine fault code is triggered when the Engine Control Module (ECM) detects a discrepancy in the expected temperature readings from the DOC temperature sensors, suggesting potentia

The SPN 3250 FMI 15 fault code is a diesel engine diagnostic trouble code indicating a high temperature at the Diesel Oxidation Catalyst (DOC) outlet. This code is triggered when the Engine Control Module (ECM) detects that the temperature at the DOC outlet exceeds the expected threshold, potentially due to excessive fuel dosing or sensor issues.

The SPN 3250 FMI 7 fault code is a diesel engine diagnostic trouble code indicating a DOC Outlet Temperature Response Error. This code suggests that the Engine Control Module (ECM) has detected an abnormal response from the Diesel Oxidation Catalyst (DOC) outlet temperature sensor. The ECM relies on this sensor to monitor exhaust temperatures and ensure proper aftertreatment system operation.

The SPN 3250 FMI 0 fault code indicates that the Diesel Oxidation Catalyst (DOC) outlet temperature is very high. This diesel engine fault code is triggered when the Engine Control Module (ECM) detects a temperature reading from the DOC outlet that exceeds the expected threshold. The ECM uses this diagnostic trouble code to alert technicians to potential issues within the aftertreatment system.
