FAQs

SPN 3238 fmi 2. This falls code leans towards commonly a faulty SCR outlet NOx sensor. Thoroughly inspect the wiring and if the wiring checks out OK, replace the sensor.

The FMI may indicate that a problem with an electronic circuit or an electronic component has been detected. The FMI may also indicate that an abnormal operating condition has been detected. The codes are displayed in the form “SPN – FMI”.

SPN is short for suspect parameter number. It identifies which electrical circuit, part or component of your truck isn't working properly. FMI stands for failure mode identifier—this part of the fault code tells you what type of problem your truck has.

It's important to repair or replace a faulty NOx sensor quickly to protect your engine and aftertreatment system. You can drive for a short time with a faulty one, with the engine running rich and over-using DEF, but the ECU will eventually send your truck into limp mode and engine derate.

Can I drive with a bad/faulty NOx sensor? No. A faulty NOx sensor may prevent the engine from maintaining its emission standards at an acceptable level, or in more extreme circ*mstances prevent the engine from starting at all.

Of course, you can reset the NOx sensor by yourself. Use a special obd2 scanner, follow the steps according to the prompts, and you can realize NOx sensor reset.

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.

FAILURE MODE IDENTIFIERS (FMI) Now that we have defined MID (The component) and PID (types of data), we can talk about Failure Mode Identifiers (FMI). Every diagnostic trouble code (DTC) that you find will have an FMI.

SPN 1592/FMI 9

Description This Fault Code Indicates a Missing Message from the Antilock Brake System (ABS) Module. Check as follows: 1. Check for multiple codes. Are there any SPN 168 (battery voltage) fault codes present?

SPN: 251

This fault indicates that the real-time clock in the ECM lost power. Possible causes for this fault are weak or damaged real-time clock battery, damaged wiring or connectors between the battery and ECM, Or the vehicle battery power to the ECM is lost.
