How Do Freightliner Fault Codes Affect Truck Performance?

Fault codes signal that the truck’s control modules are detecting abnormal readings or component failures. Some codes trigger reduced power or speed limits to protect the engine and emissions systems. Addressing these early helps prevent compounding damage and unplanned downtime.

What Makes Freightliner Aftertreatment Systems So Sensitive?

Freightliner aftertreatment systems rely on sensors, temperature thresholds, and proper exhaust flow to function correctly. Short trips, excessive idling, or failed components can interrupt regeneration cycles. When that happens, warning lights and performance issues usually follow until repairs are made.
