MIL ON - DTC 13 Manifold Vacuum Sensing Hose Set
18-40Engine Management DTC 13 - Manifold Vacuum Sensing Hose Crimped - Check Vacuum Hose Routing
MODEL: 94 MY XJ12
DATE: 3/94
ISSUE:
The CHECK ENGINE light on and diagnostic trouble code (DTC) 13 flagged.
ACTION:
on vehicles up to VIN 692643, remove the passenger side underscuttle panel and check the routing of the manifold vacuum sensing hose to the fuel injection ECM. The vacuum hose must be routed so that, when the underscuttle panel is reinstalled, the hose cannot become trapped between the climate control system aspirator and the rear edge of the engine management ECM mounting plate.
Beginning with VIN 692643, the vacuum hose has been re-routed, avoiding the possibility of it becoming trapped.
