Got a engine light and when I checked the codes I came up with a 3361 . Said engine catalyst dosing unit ? Hope this makes sense ? This bus has a cummins engine

On QSOL code 3361 is Fault Code: 3361 Intake Manifold 1 Pressure - Abnormal Rate of Change I used a 2015 ESN for an ISB Check for primary fault codes **Plugged EGR differential pressure sensor supply ports** Intake manifold pressure sensor stuck in-range Leaks in the intake air system Charge air cooler system leak Aftertreatment Diesel Particulate Filter Regeneration Analyzer Test EGR system leak or restriction
the EGR delta p ports is what i would clean out then retest
