1998 JAGUAR X308 dtc code

With EM024 disconnected measure the insulation resistance
between sensor pin 001 and sensor body. 1
Repeat for pin 002 and sensor body. 2
Is the resistance > 10 MOHM?
Yes GO to G11
No Renew the O2 sensor and reconnect all plugs.
GO to G10
G10: STOP
Perform appropriate service drive cycle and check for the
presence of DTC. 1
Has the fault code cleared?
Yes STOP
No Contact Jaguar Service
G11: SIGNAL GROUND 1 CONTINUITY

With EM010 and EM014 disconnected, measure the
resistance between EM014/004 and chassis ground EM008L. 1
Is the resistance < 0.5 OHM?
Yes GO to G14
No Inspect connector EM014 for co rrosion, damage, or pushed
back pin.
Inspect ground stud EM008L for corrosion or damage.
Inspect harness / spli ce EMS36 for damage.
Repair as required an d reconnect plug(s).
