TECH TIP

NOTE: For JL MIL On - P0456: Before replacing this part due to fault code P0456, check for terminal/connection issues
on XY465A connector. XY465 connector is part of a jumper that runs between the ESIM assembly and the vehicle
harness. Vehicle Harness Connector is clipped onto the right rear upper shock mount bracket. For JK MIL On – P0441:
Before replacing this part due to fault code P0441, check for restriction due to plastic over-flash in the Purge Hose Port of
the Intake Manifold. If there is flash in the Purge Hose Port of the Intake Manifold and the vehicle is 2016 MY then replace
the Intake Manifold and send to QEC. Otherwise, remove the flash with a 5/32” drill bit and clean the Intake Manifold of any
flash debris. For RT MIL On – P0456: If ESIM needs to be replaced for fault code P0456, check the Vapor Line, Fresh Air
Filter and the Black Frame Rail Blocker for water ingestion. If water ingestion is found, replace the ESIM and the Jumper,
Vent Recirculation Tube.
