Hi my name is***** is the complete model number from the engine ID tag so I can gove you the correct troubleshooting for your engine for these codes?
This fault code becomes active when the aftertreatment diesel oxidation catalyst inlet and aftertreatment diesel particulate filter inlet temperature sensors do not detect the presence of a catalyst in the aftertreatment system. This can be caused by tampering with the catalyst system, the catalyst has been removed from the vehicle, or a damaged catalyst
Fault Code: 1664PID: S380SPN: 3050FMI: 11LAMP: AmberSRT:
Catalyst Missing - Condition Exists. The aftertreatment catalyst in the exhaust system is not present.
Active aftertreatment diesel particulate filter regeneration will be disabled
Fault Code: 1922PID: S324SPN: 3251FMI: 0/0LAMP: RedSRT:
Aftertreatment Diesel Particulate Filter Differential Pressure - Data Valid but Above Normal Operational Range - Most Severe Level. The soot load of the aftertreatment diesel particulate filter has exceeded the recommended limits.
The stop engine light will illuminate. Severe engine derate.
This is an indication of a soot plugged DPF system. You will need to service and clean the DPF system as well as replace the DPF filter. Then try a succesful regen to reset the system. Let me know
