PROBLEM
Certain C4.4 Industrial Engines may have a problem with the DEF injector 459-7216.
The internal seals within the DEF Injector may fail and allow DEF to leak into the injectors electrical connector housing. Once DEF enters the electrical housing and contacts the electrical pins a DEF Dosing current fault is triggered. This is usually accompanied by an external DEF leak being seen in and around the injectors electrical connector. DEF Dosing Unit/Actuator Diagnostic Trouble Codes (3361/3821) can be triggered which can lead to a system inducement.
