Volvo Trucks North America produces the D13 engine, one of the bestselling diesel engines in the world. The D13 is known for its highly efficient SCR aftertreatment system — but this efficiency comes with a complex fault code system that can be frustrating to diagnose without the right tools. Volvo codes often cascade: a DEF quality fault (SPN 3031) can trigger a dosing fault (SPN 4334) that escalates to SCR inducement (SPN 4364) limiting vehicle speed to 5 mph.
