SPN 2791 FMI 18 – Smart Remote Actuator 3 (EGR), Learn Span too Small Fault Code (Symptoms, Causes & Fix)

The SPN 2791 FMI 18 fault code is a diesel engine diagnostic trouble code indicating that the Smart Remote Actuator 3, specifically related to the Exhaust Gas Recirculation (EGR) system, has a learn span that is too small. This means the Engine Control Module (ECM) has detected an issue with the EGR actuator's ability to properly calibrate its range of motion, which can affect engine performance a read more

SPN 2791 FMI 16 – Smart Remote Actuator 3 (EGR), Learn Cycle too Large Fault Code (Symptoms, Causes & Fix)

The SPN 2791 FMI 16 fault code indicates a problem with the Smart Remote Actuator 3, specifically related to the Exhaust Gas Recirculation (EGR) system. This diesel engine fault code suggests that the learn cycle of the EGR actuator is too large, meaning the actuator is not operating within expected parameters. The ECM detects this issue when the actuator's movement deviates significantly from the read more
