ISSUE:

VIN Range: 188105-221234
^ 1994 Model Year XJ12 Vehicles

Some XJS 6.0LV12 and XJ12 series vehicles within the above VIN ranges may experience customer concerns of the 'check engine' malfunction indicator light illuminating with diagnostic trouble codes (DTCs) FF44 and/or FF45 stored. These DTCs show an inconsistent reading from the Heated Oxygen Sensors (H025). The H025 are giving a faulty reading due to a slight degradation of the engine to body ground straps.
In order to prevent this issue occurring again, two supplementary ground straps need to be added to all vehicles within the above VIN range.
