What is SPN and FMI?
Suspect Parameter Number (SPN) Represents the SPN with error. Every defined SPN can be used in a DTC. Failure Mode Identifier (FMI) Represents the nature and type of error that occurred, e.g., value range violation (high or low), sensor short-circuits, incorrect update rate, calibration error.
What is an SPN code?
The Suspect Parameter Number (SPN) is diagnostic fault code terminology found on some of our equipment using a J1939 CAN data link.
What is EGR position sensor?
